I have one in .223 and various other calibers.
I have never been able to get the .223 barrel to be consistant and am looking for ideas to try.
Facts,
I shoot cast bullets only.
It will shoot one time at the range and do fairly good and the next time be abismal.
I take it down to transport.
This does not affect other barrels.
Ideas,
Read an article about putting a rubber" O " ring between the barrel and the fore grip.
Haven't tried it yet and am not sure just what if anything it would do.
Anyone have any knowledge on the "O" ring idea or any other ideas for that matter
