RE: good copper remover??
When that sps varmit gets about 200 to 250 rounds through it it will shoot better.I am hoping that when I get that many through my sps reg barrel it will be more constant with different loads.Right now it loves the 40 gr BT.Shot some hor match and sierras in it last week and they shot very good also.(52 and 53 gr).
The last several years with every new gun i get I take and give it a 200 stroke JB treatment(it's on the jar)includeing muzzleloaders and don't evn worry about breaking one in with cleaning between rounds,just clean it after the day at the range.When I start out with a new barrel I want it as clean as possible to start.
