I’ve got two 17 Remingtons. One a factory 700 bdl that’s been shot a lot. It has a very rough throat and I can usually shoot 150 or so rounds through it before I start missing p dogs that I shouldn’t have. I’d have to look at my notes but I shoot vmax’s probably over 2230c. My Lilja barrelled 17 acts just like anything else on a 223 case. I’ll run a few wet patches through it and a few strokes with a wet brush as I drink a beer at the end of the day, run a few dry patches and shoot it again the next day. I think I’m shooting cfe223 in that one. I think the 17’s fowling so badly is probably a bunch of bs passed on from long ago.
