Sierra 107 TMK Load Data

[Nine Banger]

Haven’t really had any great groups using H4350. Decided to try H1000. No pressure signs, so I’ll step it up. 20” PBB hybrid lite and OG6.5 on a Tikka.View attachment 1059918

Nice shooting.

46.2 should be about jam full up to the neck, how much farther are you going?

N565 won't spike in a 6 creed case either.

I’ll probably try another 1/2 grain and see where that puts me.

That’s some good shooting! My groups were around 2” with the h1000 in a 243 tikka, so I went to h4350. I was getting 2970 fps average with a 20” barrel, so pretty fast.

This was my experience as well. Much better with H4350 vs H1000
