Good load for 7.62x51 with 1/10 twist?

That second pic doesn't look too bad in terms of seating depth. If you know the OAL, I can probably run it in quickload and give you a ROUGH pressure curve

Here's 2 different one's for .308 that have shot .5 MOA out to 600 on a good day with an accurate barrel and shooter. Provided good brass prep, bullet and case sorting etc. Ditto on seating depth and would add, you need to chrono for everything. OCW, COAL and neck tension. Find what the rifles likes. After all that, both of these have worked very well for me:

 

175 SMK - 42.5-43.0 g IMR 4064 (all purpose load)

 

185 Berger Jugg - 43.5g Varget (F class and 1,000 yard load)

 

BR2 primer on both.

 

*The Berger 185 is much better @ 1,000.

I have had a good bit of success with AA 2520. It has a  reputation at Camp Perry that goes back a very long way. Automatic's are very different animals than bolt actions. AA2700 works great in 06 Garand's. Try some Federal match primers if your loading for bolt action.

Finally got a caliper on these...





Two different powder charges with IMR 8208 XBR: 37.0 and 37.6 grain with 178 grain AMAX.

All loaded in LC 7.62x51 brass.

So to crimp or not crimp? How much is enough?
