Hi.

Any of you guys ever used this stuff in an Armalite? Recently I tried some of the 62 (or 64?)gn stuff and I would be luckey if I could hit a dinner plate at 100yds. Didnt group at all.

Mine has a 1:9 twist.

The 55gn Barnaul groups okay enough for me but leaves the chamber pretty dirty with that red sealant they put around the primer and neck (like a varnish)

Cheers in advance.
