fast 77 tmk loads

[Steve Ladino]

I have pretty good loads for the 77 tmk in an 8 twist 223 Rem. but they are about 2600 fps. I'd like to get a max load that gives great accuracy and more speed, anybody find one ? Thanks

I shoot 23.3gr 8208 in a 20" Wylde chamber, should get you another 100-150fps.

My AR with its 24" Krieger 1: 7.7 shoots the Sierra 77 gr tipped Match Kings extremely well.
24.5 gr Viht N 140, Fed match primer, Lapua brass, Loaded length OA 2.365" Single loaded.
