So I recently had a 6.5 GT take a 50 fps nose dive in the middle of a hunter match with 1600 rounds through it, measured .075 erosion to the lands.
I adjusted seating depth, increased the charge .5 grains and put a few hundred rounds through it before things really started going to shit. I was running 34 grains N150 with 142 smks, shocked I didn't see at least 3000 rounds. It was a Benchmark Sendero.
I'm running a Criterion 223 wylde for PRS, it's been a picky bastard from the beginning but shoots 75 vlds real good toucking the lands, loaded with 24.5 grains N150.
I'm getting ready for the finale Aug 23rd and my accuracy is starting to drop! I'm at 2200 rounds and the lands have eroded to the point that I can't seat into them with the bullet still in the short 223 neck..
WTF is going on? Thought I'd for sure get 4000 rounds from a 223..
Is N150 super hard on barrels?
