My hunting partner and I shot the barrels out of four 17 remingtons shooting 28.0g of 760 with a 25g bullet, we were shooting p. dogs.
Here is the problem, the 17 Remington cartrige has a lot of freebore designed in the SAAMI spec reamer. When the rifle is new, the bullet does not have to jump very far before it engages the rifling, aligning the bullet to get the bullet started straight in the barrel.
As the leade grows from shooting, the bullet has to jump further and further before it engages the rifling. At some point, the accuracy goes to heck. I suspect that the barrel life could be extended somewhat by shooting the 30g Bullets, more bearing surface usually helps as a throat starts getting worn, but you will not know until you try.
We got about 1500 rounds through those Remington Chrome moly barrels before the barrels were toast. For just coyote hunting, we would have probably got 2000+ rounds out of the barrels, but what a pain in the rear end those barrels were to clean!
