I have a new 7mm-08 with a new Bushnell 3x10 3200 scope. i have tried multiple handloads. it will not group at MOA. average about 1.5 inches. used several powders--best groups with 47 gr H380 and 48gr IMR4350. used 139 Hornady BTSP interlock, CCI 200 primers and new rem cases.all screws in mount and bases tight. I shoot off of sandbags on concrete bench, i let rifle cool after 3 shot groups. triggger is crisp. have scope on 10x.

is there something i am missing or not doing correctly.

is this rifle a reject or is there something i could do to get it to MOA at 100yds?

I would contact TC, though I might not tell them right away that you used handloads. I have heard that some gun companies regard handloading in their firearms as an act that voids the warranty (in their eyes). How does it do with factory ammo?

It could be your rifle just isn't too fond of the SSTs. Try a few different bullets.

Does it come with test target?

Maybe buy a box of factory match ammo and take it for a spin?

Do that and then you have some recourse with the company. IE hey, i sandbagged it and ran federal gold match and it would NOT group less than XX.

IF you say handloads, it makes lawyers nervous : ) I would not say it lol.

Normally T/C gives brand of ammo used for test target if so purchase that ammo. My T/C Icon shot same as test target with Hornady vmax ammo.

Different bullets give different results. Try various manufacturers, bullet weights, etc., etc.

I want to know the outcome of this. I've been thinking about one.

The Venture is not guaranteed to shoot MOA with all ammo. Every brand of rifle will have a sweet load that it shoots well, you just haven't found it yet.
Another brand of bullet or powder combo, may halve the group size that you are getting right now.
As others have mentioned, for your own satisfaction, find out what ammo was used to verify your rifle's accuracy.

"...as guaranteed..." Hi. Guarantees like that usually have specific ammo mentioned in the 'small print'. No company can guarantee MOA accuracy with all ammo.
Your rifle should have come with a target and what ammo TC used.
"...voids the warranty..." SA Inc., for one.

I remember a company by the name of Kleingunther that guaranteed 1/2 groups and they would provide the target and the load that the rifle liked. Thy also had a very effective muzzle brake. Sadly I think they are out of business

hoghunting btsp interlocks aren't sst's but your are right that it may not like them.

paul yakupzack Do try some factory ammo first and what the factory used if you can. Still may not shoot it's best till you break in that barrel. Just a box of ammo can take a good part of the day.

i have tried multiple handloads. it will not group at MOA. average about 1.5 inches.

Are you sure it's the rifle? How well do you do with other guns?

I thought my first handguns wouldn't group worth a hoot until I let someone else try it. After a few pointer I was doing better, but still not as good as him. :(

Dont panic..! starting with a good solid rest (no gun movment). Adjust the trigger so it is right for u.Make sure u are using proper form.Do all things needed to produce an MOA or better group they can be easily overlooked.U will just have to find the right load.U might want to try playing with the distance to the lands on the load u have now could make a huge improvment.

TC advertized themselves pretty well in outdoor channel with prominent hunting personalities like Jim SHockey and many others. They should be good.
Try calling them and ask what factory load they used .

after repeatedly tried 4 different powders,3031,4350,H380 and 4064 with the Hornardy 139g BTSP interlock, best i could do was 1.5in at 100yds an occasioanal 1 in group. A month or so a go i bought a box of REM 140 PSP flat base bullets. I had narrowed my powders to H380 at 47 grains and 4064 with 39 or 42 gr with the 139s so i loaded the Rem 140 up and shot multiple 4 shot groups at 100 yds. shot one group with the Rems next group with the Horn 139s. the rems shot 1inch and Horn 139 varied for1.5 to 3in. that flat base on the Rem 140 bullets must make a difference? i did have an occasional flyer witht he REMS usually on the 4th shot of a group??

I also started using a led sled to really steady my aim off of a concrete bench. I shot a 3in group with 42 gr of 4064 with the Rem 140 at 200Yards this am. I also let the rifle cool 15 minutes or more between 4 shot groups.

Has anyone else noticed that flat base bullets will shoot more accurately in some rifles?

Thanks to the poster who suggested i try flat base bullets, i think it was on another forum though!

Sierra Pro-Hunter may be another option you can try

First thing first- If this is a gripe about the rifle not meeting the guarantee, contact TC, give them a chance to fix the problem, then post about it.

If this is simply trying to figure out how to get the rifle to shoot better, edit your original post to reflect that intent.

Second, go through and the rifle a check up. I am not familiar with the details of a TC Venture, but there are some items to check common to all bolt actions.

Inspect the condition of the bore and crown.

Remove the stock from the action and check the bedding. Make sure the action fits in the stock with no binding. Check to see if the bedding is bending the action when the action screws are torqued. Check the forearm for sideways pressure, too much upward pressure or uneven pressure. When re-assembling, torque evenly and to the proper value.

Disassemble the scope rings & mounts. Clean & degrease them. Check that the mount holes are correctly aligned. Check that the mounts sit on the action correctly. Use the proper torque value when reinstalling. Inspect the fit of the rings to the mounts. Make sure they align correctly when installed, both left & right & vertically. Use an alignment tool. Again, use the proper torque value.

Clean and degrease the scope. Center the crosshairs both in windage and elevation. Inspect for damage. Install scope, use proper torque values. If using Redfield style rings & mounts, adjust windage using the two screws holding the rear ring in place. This can be done either with a bore sighter or by shooting on target. Once it's close only minor windage corrections will be needed from the scope.

Until these items are checked and any corrections made, it's futile to check the accuracy of the rifle

You've only used one bullet. Let's not get carried away thinking that the rifle won't shoot. You have to find what it likes. Bullets too, not just powder.

I used 2 bullets a Hornady 139 gr BTSP and a REM 140 gr PSP corelock flat base the flat base seems to shoot better about 1moa.the 139 boat tail shot 1.5 moa at best.

Has anyone else had better luck with flat base bullets in 7mm08?

Contact T/C and find out what kind of ammo your gun is supposed to get 1 MOA with.

If your gun won't shoot MOA with that ammo and doesn't have a shot out barrel from shooting thousands of rounds, T/C will probably tell you to return the gun to them for testing. If they can't get it to shoot MOA, I'm confident they'll make it right one way or another.

By the way, the not handloads thing is mostly because they don't want you blowing up their gun with a bad load and then blaming them. I don't think that applies in this case since apparently the rifle is in good condition. I've returned a couple of barrels over the year; one to Blaser and one to T/C and made no secret of the fact I shoot handloads and there was no problem. The Blaser barrel was replaced with a new one and the T/C barrel was fixed.

the venture was purchased new last december(2010) and has been shot about 150-200 rounds, just about all reloads nothing over max listed charges either.

I am happy with the gun but it was not an out of the box MOA shooter for me. i suppose my shooting technique has improved. and the barrel has worn in some.

If it does just sub 1.5MOA, you'll be fine.

My Model 7 in 7-08 groups about 1 1/2 MOA with some factory ammo, and can do MOA or better with handloads. 140 grain bullets work best in mine, I can't get 150s to work well at all.
Try changing bullet weights in addition to your powder.

I suggest you try your hand using either Sierra MatchKings or Hornady BTHP Match/A-Max. If neither of those shoot with the range of powder you've got, I'd say it just isn't going to do it. They may not be your hunting rounds that you want to use, but they are both very accurate bullets and should help show what the rifle can do.

Maybe because of the fact that you are using handloads. Call T/C. Get the info for the type of ammunition said rifle was tested with, and use that. If it groups with that, you're golden, and feel free to experiment with hand loads after that. If you don't group properly, then call them back and tell them that their rifle isn't performing as advertised. If they're as decent as they should be, they'll make it right. Plain. And. Simple.

As the others have said your rifle should have came with a test target....at least my Icon did. It gave a date, an employee ID # that performed the test, and what type of ammo was used during the test. FWIW, my Icon performs as advertised. I also had a problem with the 1st Icon I bought but T/C replaced the rifle and did so in a very timely and efficient manner, IMO.

mine did not come with a target or any info about what type of ammo it would shoot 1 moa with. does anyone know what ammo they use to test the Venture?

It looks like I may be mistaken about the Venture being sent with a test target like the Icon is. I would call T/C and speak to them. I had my best luck contacting them at 8 AM EST when they first opened.

Just a thought, but do you keep your OAL consistent? Also, have you played with different OALs for the particular loads that seem to shoot better than the rest? I have a 30-06 that would consistently shoot ~1.5" 5-shot groups with a particular combo of IMR4350 and 165gr sst. Once I started playing with OAL, I found a seating depth that dropped the average groups to ~1" with many coming in well under that. Might be worth a try.

My understanding is that boat tail bullets are for loooooongrange, and that flat base bullets will perform better up close.

Grumulkin
August 28, 2011, 10:45 PM
Boat tail bullets have a better ballistic coefficient so are better for long range shooting but that doesn't mean they'll not perform at close range. Flat based bullets may perform well at close range and, since for a given weight are shorter than a boat tailed bullet, are easier to stabilize with slower twist rate barrels.

You didn't say what primer you are using either. It does make a difference! I had a Winny feather weight in 06 I spent a lot of time with which I could not get to group.Turns out the scope was playing a large part of the difficulty. Afer changing from a Bushnell to a Lepould with better scope rings, my 5 shot groups srank down to sub moa. I bragged about the group size this rifle could shoot but I was out of ammo. I reloaded with the bullet and powder but found I was out of CCI primers so I used Winchesters. This was a mistake and the group opened up to 1 1/2 moa. I also found how far away you seat the bullet from the lands an make a huge difference. I also use Winchester brass for my feather weight. Mixing brass won't work either.

The point being unless you are shooting what the manf. shot to get a small group size and then duplicating the group size blindly and not knowing what was used can be a pita.

Once I find what the tifle likes It takes a lot for me to change bullet, powder and primer, and even case manf.

I would bet if you could find a box of Federal Gold match your rifle would shoot better. I have not found a gun in good condition that would not shoot it better than about any thing else. Good luck

Why the hell do you need to shoot better than 1.5 inch groups with a 7mm rifle? What are you going to shoot? Butterflies? I'd be overjoyed if my hunting rifle shot 1.5 inch groups. I'd brag about it with my hunting buddies over the campfire and bourbon.

Any hunting rifle that shoots 1.5 inch groups is a great shooting rifle. If you want a target rifle and are going to shoot in competitionthen you need to get a target rifle. A TC is not a target rifle. We used to be happy with any hunting rifle that grouped 4".

You have a fine rifle thar. On a good day you'll probably shoot MOA anyway. Not that it matters. Our eyes, the wind, heat and parallax have something to do with groups. Not to mention bullet type, load, case, primer and all of the other stuff. Don't waste your time trying to squeeze MOA out of a hunting rifle. Your shoot'n iron is just fine. Better than most.

Germster, to quote the link listed above: 3 shot group in 1" or less at 100 yards, T/C Venture will shoot MOA groups guaranteed. If not completely satisfied T/C will certify MOA accuracy or replace with a new Venture.
If the Venture wasn't guaranteed to shoot MOA, I'd agree with you about being happy with 1.5 MOA groups. But, the Venture has the 1 MOA guarantee. I also agree with the other posters about branching out & trying different bullet weights, calling T/C for recommended factory ammo, etc.
