RE: Breaking it in
Alot of people say that this is not needed...
The powerbelts will work better than the round balls.. since the round balls use a patch. Youcan also accomplish the same task w/ some JB BorePaste.. or valve lapping compound.
I personally shot 10 or so lead Hornady 250gr lead conicals... And my Omega shoots awesome as far as I'm concerned. It may have shot as well w/o the "break in"... butI don't know for sure.
