Re: Freebore in a hunting rifle.
Buffalobob put it right on about Weatherby's. I have 2 and found it frustrating at first to get the 'ragged' hole from these rifles. They both shot better AFTER 150+ rounds! The first two shots are cutting now, the third is at 10:00 1/2"out and these are with #1 contours at 200 yrds full house loads. (Why bother with anything else if shooting a mag, beside Weatherby's shoot at the top of the pressure curve best). They need that pressure point up front too, don't remove it, if anything, rebed. Weatherby's were deamed 1 shot kill rifles and I have found that to be true. Take your time, work up safely, they will come in as you want. I love my Weatherby's! One is a beautiful Lazermark and the other a Lightweight both .257's.
Good luck on your choice, there is help if you have issues with any Weatherby.
