...The muzzle velocity for the 10-shot string of the Wolf Gold 55 grain FMJ ammunition was 3213 FPS with a standard deviation of 25 FPS. For comparison, IMI M193 had a muzzle velocity of 3274 FPS when fired from the same barrel, with a standard deviation of 18 FPS.
... three 10-shot groups of the Wolf Gold were fired in a row with the resulting extreme spreads:
2.13”
2.60”
2.44”
for a 10-shot group average extreme spread of 2.39”. The three 10-shot groups were over-layed on each other using RSI Shooting Lab to form a 30-shot composite group. The mean radius for the 30-shot composite group was 0.76”.
For the last month or so I've been sending quite a bit of the new Wolf Gold .223 down range. It's really good stuff, and honestly it surprised me. Here's more info.
