1000yd 3006 load

[Gunnerboy]

Looking for input based on EXPERIANCE for a good 1000yd load preferably with 190 SMK's or 220 SMK's. My rifle is a Rem 700 that i true'd the action up and put a 1.25 shilen barrel on, Match spec chamber was cut by me, has a HS precision stock, so the rifle is set up right. Just looking for a good load to play with. So far i have some 220 SMK's loaded up with 50grs of IMR 4350 and a cci 34 primer.

I highly suggest you drop the bullet weight to the 175gr SMK. It has the best mix of BC and weight for 1000 yards from a 30-06. (IMO of course) Why are you thinking of using a CCI#34 primer in a bolt action rifle? I would use a CCI BR2 primer instead.

With a 175gr SMK bullet I would go with a charge of 58.0gr H4350 and that BR2 primer. You will get less bullet drop and less wind drift with the 175gr bullet than the 190gr bullet. I just feel the 190gr bullet will perform better in a 300 Win Mag than the 30-06.

I ended up with a good supply of cci 34's thats why i use that one. And i thought about 175s too but not 100% sold on those yet.

 

[ArchAngelCD]

IMO, don't take my word for it. Check the BC numbers against the velocities you can generate with the different weight bullets and see which will work out best in the 30-06. Remember, like I said, those heavier bullets we made for the 300 Win Mag. The 30-06 is a great cartridge that can be loaded with a 110gr bullet to a 220gr bullets but of course your best performance will not be on the fringe weights. The heavy bullet, especially the 220gr match bullets really aren't meant for the 30-06 out to 1,000 yards.

Plug the numbers into a ballistic calculator and see what you think is best.

 

[Water-Man]

175gr. SMK is the way to go.

I would look for the best combination of bullet weight, BC, and listed load velocity, that will keep you supersonic out just past 1K yards. Look hard at the Sierras and Berger lines of bullets. No matter which one you choose, once they start to transition into subsonic velocities your guess is as good as any, as to how wide they might spread out.

I would also not decide that a 100yd group is a good one for 500 yard or further accuracy. I wold start working on dialing in your loads at 300 minimum and go out from there.

Gunnerboy,

I shot in 1,000 yard F Class Competition for several years with the custom built .30-06 shown here:



This rifle was built by Jack Krieger, and with the 190SMK's that I used exclusively, I attained 2900fps which duplicates Federal's .300 Win Mag Gold Medal Match ammo. My load is as follows:

Lapua brass
Fed 210M primer
60.7gr RL22 powder
190gr Sierra MatchKing bullet

As I said, velocity was 2900fps, and it took 30.5MOA of up from a 100 yard zero to reach 1k. Hope that helps.

That is just about what I shoot in 30-06 for 1,000 yards. The 175 grain SMK is hard to beat and I always use the CCI BR2 priming offers up much better uniformity / consistency than the CCI 34 priming in my experience. Using IMR 4350 and weighing each charge (again uniformity) I was running with 55.5 grains giving me about 2750 FPS over the chronograph if my old notes serve me correctly. The rifle was a 700 BDL trued as you have done and a Douglas barrel. Other powders I tried with good results were RE19 VihtaVouri N160.

When I was into this I also weighed my brass and used the same manufacturer brass. Keeping it together was about uniformity and consistency in my loads.

Thanks USSR thats the kind of data ive been looking for, The reason im stuck on 190gr is less wind drift out past 800 and also according to all the number crunching they are flying faster and hitting harder than 175gr. Not that 175 is a bad bullet choice IMO its best at 800 ok at 1000 and well probably not much for past that... and knowing me ill try pushing to 1500 once im done at 1000.

In the .30-06, with it's large case capacity in relation to the .308, and with a slow burn rate powder such as RL22, it allows for high velocity with heavy, high BC bullets such as the 190SMK. About 14 years ago, myself and another guy that goes by the handle of MontanaMarine on SnipersHide.com, took it upon ourself to search for the ultimate LR .30-06 load. We were convinced that with the right powder, that 2900fps could be reached with the 190SMK. Working independantly, we both found that RL22 was that powder. While the charge weight will vary according to what brass you use (60.7gr with Lapua or LC M72 Match, and 61.4gr with Norma), I have only been able to reach this velocity with RL22. H4831 at maximum charge weights produced velocities of about 125fps slower. While the 175SMK is a good bullet, the difference between the velocity that it can be driven at as opposed to the 190SMK in the .30-06 does not make up for the higher BC of the 190SMK. And, at 1,000 yard shooting, a high BC bullet is critical. Hope that helps.

That helps alot thank you, But what kind of pressure signs are you getting with that load? My elk and bear load out of this rifle before it was rebarreled was a 165gr NAB with 59.5grs of IMR4350 and a cci 34 primer.... That was just starting to flatten primers for my elevation and weather. And thats the point i dont like to push past.

 

[USSR]

Zero pressure signs with the brass and loads I specified. And, I have loaded some of the Lapua brass 5 or 6 times. Since we were basically going off into uncharted waters, we ran the load data thru QuickLoad software prior to load development. QuickLoad showed anticipated pressure of between 59,000 and 60,000 psi with the load data I provided.

"...I ended up with a good supply of cci 34's..." Excellent reason to use 'em, but they are just magnum primers.
I'd suggest you switch to IMR4064 with a 175. IMR4064 gives me extremely consistent accuracy out of my '03A4 with 168's(only our military has 1,000 yard ranges here). As mentioned, the 190's are .300 Mag bullets. Mind you, a lot depends on the rifling twist.

 

[mavracer]

If you're gonna stretch it past 1000 I'd say you're right in using 190 or heavier bullets. As Don says the better BC trumps the little bit of MV you gain.

I'd be interested in how fast you could get 208 A-maxs going with some of the newer powders, I've heard guys getting 2600 with a 308 surely you could get 100-150 better on a 06.

I've got some of those 208gr A-Maxs and have been meaning to try it in my .30-06. I suspect I could get 2750-2800fps with my 26" Krieger barrel.

[Gunnerboy]

Yeah ive been eyeballing the 208 amax bullets alot lately.... but than there is the 210 Nosler long range.... So many choices not enough paycheck.

That'll keep it supersonic out to 1500

Because I don't have data for the 190gr SMK bullet in the 30-06 I will use the data provided by Hodgdon when both are loaded with IMR4350.

175gr 2780 fps @57,100 PSI
190gr 2647 fps @58,500 PSI

@1000 yards the 175gr bullet will retain a velocity of 1320 fps, the bullet will drop 387.79" and with a 10 mph crosswind the bullet will drift 86.75". The time of flight is 1.6 sec.

@1000 yards the 190gr bullet will retain a velocity of 1301 fps, the bullet will drop 417.5" and with a 10 mph crosswind the bullet will drift 86.35". The time of flight is 1.64 sec.

My conclusion, we are all correct. It seems like the numbers tell us the results are almost identical except for the bullet drop. Time of flight is almost identical and the wind drift is almost a mirror image. My conclusion, use the bullet you like because the results will come down to how well you do your job, not the bullet itself...

Even when you use the powders that report the highest velocities and the 175gr bullets are traveling much faster out @ 1000 yards the numbers change little.

175gr bullet, 1325 fps, 358.39" drop, 1.53 sec TOF, 82.44" drift.
190gr bullet, 1375 fps, 402.34" drop, 1.61 sec TOF, 84.34" drift.
