ok im looking at doing a custom barrel on the 112 bvss i have. it has a 300 winn mag barrel on it at the moment.im try to deside a few thing and would like someone elses Opinion .i am thinking maybe 25-06 ai. or 257 weatherby mag.i will be using a shilen barrel i am sure.my question is this im new to the custom rifle thing and have few questions on it.i see where shilen has a drop in replacement barrel for my savage.my smith will not use a pre chambered or fitted barrel and will not use the barrel nut he said the conventional recoil lug is more accurate.what are your Opinions on this as i dont have clue. i will be punching paper more than hunting with it.thanks.
