Looking for advice/guidance on getting a weatherby I have rebarrelled. I purchased some years ago a .300 WTBY MAG, MK V Super Big Game Hunter. I've been trying to get it to shoot 180 grn bullets since purchasing it and it's all over the target. Factory and re-loads doesn't matter. I'm convinced it's got to do with the thin barrel so I'd like to get it rebarrelled with a heavier barrel. What are your thoughts on the situation and who in Anchor town or the Kenia Pen. does reputable work?
