.223/77TMK for semi, results

[mark5pt56]

I would love to get you some WOLF primers to see if you get similar results to what we've seen with tighter groups and S.D.s.

Looking at my notes, I'm between 7.9 and 10.3 on the SD, I split the difference on the oal 2.280-2.290 on the Tikka, ES was 20. I was going to go up to 24.2 on that as it was 10.1-4.2 same lengths. 205M. My avg was within 2 fps on those at 24 and 24.2. 2869 and 2871 on 24 and 2897 and 2895 on 24.2

Again, 24" Tikka bolt

I have a load work up in progress for these TMKs using XBR8208 also. Just need to get to the range and shoot and see what shoots best for my MK12.

If a guy happened to have some wolf primers and wanted the best loads for 77 TMK with XBR or 332, what should he try?

23.4 grains 8208 with either Match Kings or Tipped Match Kings.

24.0 is where I see primers pop with 8208. 23.8 is a tack-driving load for me. No pressure issues for me at 23.8 gr.

That's the thing with 8208. There's lot variances, and it turns on you without warning. 23.8 was good for us until I bought different powder.

I really only loaded that hot stuff for defense mags. I don't shoot it on any sort of regular basis. For 77s, I revert back to a milder H322 load.

Those are really good numbers, but I'd be intrigued to see if the Russian primers helped/hurt or whatever.
