anyone have a pet load for this bullet am going to try to use them in an ar15 with a 1/9 twist barrel thanks guys

24gr Varget.

Good luck getting a 77 to shoot in a 1/9.

I'm running 24 grains of Varget for the 77 Sierra Match. Who has a 77 grain PSP? It could be interesting. The 77 SMK is a 1 in 7 or 1 in 8 twist, 69 is down to 1 in 10. Let us know how it works.

24 grains of Win 748 and 75 grain Hornady and especially 77 grain Nosler work great in my heavy barrel AR.

Some 1:9 twists will stabilize a 77 grain bullet but some won't.

What bullet are you using? PSP is an abbreviation Remington applies to some of their Core Lokt components, but they don't make one in that caliber and size. If it's a shorter bullet then it might.
