7mm Rem Mag Barrel Life at Life

7mm Rem Mag Barrel Life. Hunting rifles, a barrels lifetime of around 1,000 rounds is quite excellent, but i’d think most of us would have discarded the barrels at minimum a couple of hundred dollars seasons back. After about 1000 rounds i am noticing my groups are going up.

Different barrels firing differnt loads will vary in life. I have been wanting to cut it down to a 20” barrel because i am going to be running it suppressed. The 7mm rem mag will give higher velocities with lower peak pressure, extending barrel life.

It’s going to be shooting a fair amount of powder through a 7mm hole and that is really what dictates the life of the barrel. My 7 rm is a rem bdl as well and it shoots.5 moa with several bullets.
