Hmm, i was not impressed. Though it was still great I was sighting a new scope so i shot about 30 rounds of Federal American Eagle .223 55gr to sight it in and got the last 10 shots down to about 1/2 inch group at 50 yards. Changed to the 5.56 Hornady 75 gr TAP and was at 1 1/2 inch group with 10 shots on a new target.
Ill have to try it at 200 yrds next.
1/9 twist rifle I presume?
Shoot a few rounds at 100-200 and see if they're starting to keyhole, I bet they are.
1/8 24" heavy barrel. Maybe the extra distance is where this may level out. There was a minor breeze today too, but that was the case with the other rounds too.
Odd. That's 3 MOA, definitely not what this ammo is typically capable of. Wind probably wasn't much of a factor since a 10Mph crosswind at 100 yards only drifts a 75gr bullet ~0.65 inches.
Any other rifles to try it in? It's possible that that barrel/bolt combo just wont shoot that ammo. Maybe excessive head space and the full 5.56 loading of TAP messed with things.
Who makes your barrel, barrel free floated, what optic?
Only other thing is did you do your part shooting (two stage trigger, full rest, breaks in between each shot)? I'm assuming you did since your other groups with "bulk" ammo weren't bad.
If you have the chance, I'd shoot again at 100 yards with a difference rifle and then again with the same rifle. 8-10 rounds each. It stinks though since TAP is so expensive. At least it'll still perform well in a bad guy.
