Sorry to hear about that, I too, have screwed up recently. I've had this obsession with using a pp'd lee tl230-5r in a mosin. Actually started on it last fall, but finally got back around to messing with it and loading some ammo up this weekend. Well, I didn't remove the sticky alox from the boolits before wrapping. I think it was adhesive enough to stick all the way to the target with the slower loadings, so accuracy was...ok. But the hotter loads I loaded were all over the place, so I imagine it was shedding the patch mid-flight. Oh, well, live and learn.
I didn't get to really do much shooting with the Mauser, though using the NRA slow-fire pistol target at 200 yrds, I did get inside the 7 ring with the one shot i tried at that distance. The groups at 100 yrds were about 2-3" in heavy wind, so not as good as before but not back considering the conditions out on the mesa.
