[QUOTE="zoeper, post: 284378, member: 10682"] I shot out a .243 Win barrel in +- 800 shots and i do not consider my loads as "HOT". I was shooting anything from 70Gr - 100Gr projectiles at speeds of up to 3450 fps. When i get a new barrel i was hoping to go for a 1-9 or 1-8 twist and sticking to the heavier projectiles of 105-115 gr and the main reason is to get better LR balistics (more retained energy downrange) The question is: "is my thinking is correct" 1. I am reasoning that less speed at the word go should give me longer barrel life. 2. heavier projectiles = less powder = longer barrel life? so what is eating my barrel? -Speed; -Presure; (also higher temperature as a result) -Powder; (more powder = more gas produced= more hot gas through the barrel I would like if the "old hands"with earned wisdom or theories about this could chime in and enlighten us "not so experienced" Thanks Pieter [/QUOTE]
