7mm-300 win issues ?
i have a 7mm-300 in a lilja barrrel, gunsmith used a reamer with .312 neck
i have to turn a lot of brass off necks to get a bullet to slide in a fired case, i was setup for a .316 neck, on my last 7-300,
now i wondering easiest way to get a .316 neck in this barrel, i dont like the .312 neck and how thin the necks are on the brass,
shooting my old brass in this new chamber has pressure issues, and ok accuracy,
