Vihtavuori N133 Chronographed Loads - AR-15 (.223) 69 grain HPBT

Running some handloads of Vihtavuori N133 in .233. These are using the RMR Bullets 69 grain HPBT round, made "in-house" by RMR. Loads were

1st: N133 at 22.9 grains w/69 grain HPBT RMR Bullet and OAL of 2.244
2nd: N133 at 23.5 grains w/69 grain HPBT RMR Bullet and OAL of 2.244

Not much of a difference between loads - will need to push these out past 100 yards soon.

Rifle used was an Adams Arms AA-15 - piston driven w/a 14.5-inch barrel and a welded bird cage, 1-7 twist. Will test this round w/an 18-inch barrel in the future.

Thanks for stopping by!
