I have only run about 100 rounds through this gun & I have it driving tacks. Took a 160bc at 425yds on a power line last year & several running pigs at various distances. I drag it through the mud, its beat up and dinged and I love it to death. The only problem has been the front ramp in certain lighting situations causes a flash back through the scope because of the mounting height I prefer. The flash cost me a monster last year right before he hoped a fence.
Sooo...fineness hack saw, slight fineness filing with oil, light sanding/wooling. Everything stayed nice and cool. Just finished and am bluing as we speak. Not gonna be a show peace. But looks pretty good. Looked through the scope at every possible angle under strong lighting and its all good. Can't wait to shoot!!!
