Can someone please explain
I need help analyzing this. My friend just blown my methods of meticulous handloading out of the water. Anyway, a few months ago, we decided to try the Nosler 168 Competition on both of our 308, and see if we can use the bullet for hunting. Well to make a story short, my rifle likes the Nosler and not on his. He handed me the rest of his already handloaded ammo, around 100 rounds in all, and give up on Nosler all together. I tried several of his reloaded rounds in my rifle and it chambered okay, even though he was using brass that was once once fired from his rifle. Except with occassional trimming, which is as far as his case preparation goes, he rarely does anything else on his brass. The other day, I tried his handloads on my rifle and the result was short of amazing.
Here's the spec of his handloaded 308 ammo
168 grain Nosler comp
43 grains of H4895
Federal 210 Match Primer
Winchester Brass/once fired and partially necksized/trimmed with no other case prep
COL 2.825 AV. jammbed slightly to the land
