[QUOTE="Jinx-), post: 524116, member: 19791"] I had this rifle for 5 years, but it always get heavy copper buildup after 10 - 15 shots. On this one I used KG-12 and it took 4 hours with patches and brush to get copper out, this is not just one spot it looks like copper gets build through out the bore, on lands and valleys, some places deep down the barrel are shiny red. I didn't fire solid copper bullets through it, 20 shots I made where 150 gr Nosler BT and 140 gr SGK. Also it groups better with 3 shots, so I do not fire 5 shot groups with it. [/QUOTE]
