300 rum

Ok. That's what I thought. This has a sporter barrel so it is pretty thin. When I am target shooting I give it time to cool a bit between shots. I try not to let the barrel heat up that much and I clean it when I get home. Guess I should start saving for another barrel.
Would it make a difference dropping from 210g bullets down to say 180's or even 168's on barrel life?

I reckon lighter bullets going faster will do your barrel in faster. Stick with what you are using and use it for hunting it will last you a long time. Get yourself another rifle like a 308 for range use.

I've got a Shilen select match #4 on mine. 28" long. Shoots 180 Sciroccos, 200 ABs both with Retumbo and Re25 really well.

shoot 3 and let er cool off. work up load in 1 gr increments until you find accuracy and fine tune with smaller increments from there... play with OAL too. I usually just load to max magazine length and increase charge until accuracy comes in... usually close to max with the rums I have. I shoot accubonds in 7, 300, and 375. I like the idea of a fairly tough bullet that will fly well too. Anyway, thats my game. Others may do it different and better.
