What sort of barrel life should I expect from it in terms of rounds through it.
Also what bullet velocity would you consider to be too fast and damaging to the barrel due to the excessive speed?
Sorry for the noobie questions, I'm learning.
With good cleaning practices it should shoot well to 4 or 5000 rounds (More than most hunters
will ever shoot).
Velocity is not the only thing that causes barrel wear. It is a combination of velocity and powder
charge. Example; A 308 with a velocity of 3000 ft/sec will last a long time but a over bored
.308 that uses 2 to 3 times the powder will erode the barrel in 1500 to 2500 rounds even at
Some powders are also more erosive than others. and some barrels wear faster than others.
With the rifle you have don't worry about barrel ware, and if the rifle starts to shoot poorly
just re bed and give it a thorough cleaning and you will be surprised how well it will shoot
