On the low end 1911’s I find that if you just polish the feed ramp with a bit of Herbs Yellowstone on a piece of belt leather folded to a “U” that fits the feed ramp, fixes them up real good.
They will eat anything if you do that.

I entered a contest the other day for a Ruger M77 Hawkeye rife, chambered in 7mm-08 Rem. I’m not at all familiar with that round. What would it be suitable for? Varmints, big game, zombies?
