THIS IS 100 YARDS!! NOT 50!! like my normal tests!!
These are ALL 20k off the lands, nearly exactly.
Some 55 Grain bullets KEY HOLED!! and were not stable!! 55 grain is very iffy!! So we learned generally, 55 grain is too light for 1:6.5 twist. 60-95 grain is the range I think.
Wow! take a look at some of those groups!! RL15 with 77 SMK Moly!! That is a very tight group for any NON BOLT gun!! 5 SHOTS! How about the Accurate 2460 groups too! TAC pretty good! Of course Norma 203B is good, its nearly the same as RL15!!
That is a lot of groups SUB 1 MOA. All less than 80 grain...
Then why is it I can't get groups sub MOA all day like this with the 80 grain + bullets? Even when I put them exactly 20k off the lands?
I am starting to think its the heavy bullets themselves, the design. because the moment I switch to Berger 77 OTM or 77 SMK, its sub MOA in the same range session. Like a light switch.
So...if you want a great 100-200 FPS better than 5.56 NATO, using 77 grain bullets? Valkyrie is what you want.
