If it were me I would buy a Goodoien barrel. My boys have a matching pair of TN rifles (RH & LH) with this barrel & from the first time we shot them, both of them shot cutting shot cloverleaf groups at 25 yards. We load a .375 ball, .015 Oxjoke patch, Lehigh Lube, .35 grains of 3F Goex in them. These barrels have a lead cast slug poured into them & they are then hand lapped before they leave the shop, so no breakin period is required. They are Superbly accurate..... TOW used to sell them don't know if they still do or not. :thumbsup:
