    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.

    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 .

    the rest of the story on my Venture 7mm 08

    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.
