I get that, but 460 rounds is horrible barrel life!?Take a V6 out of a vehicle and insert a V8 and wonder why the back tires are wore out.
With DEs experience with +P, would they be promoting it knowing of such poor barrel life?
I had considered doing a +P so would really like to know if this was due to throat design or metallurgical.
It'd be interesting to know what Bartlien did to confirm that the metallurgy was correct.
