Went to a very well attended woods walk today (23 - 24 shooters; 16 shots total) and was really surprised to win 1st place as my offhand BP shooting of late has been pretty poor. I think a change in meds (reduced!) helped as did holding and aiming the rifle during the week prior to today's event. However, this wasn't a "slam dunk" as I had patch/RB problems today. To wit, I determined several months ago that my .50cal. Lyman GPR shoots best from the bench with a .492" RCBS RB which I cast, + .021" muslin patches. Unfortunately they were unbelievably difficult to start and seat. On the verge of panic over having such a miserable combination, I figured I had nothing to lose by using the 100% cotton flannel cleaning strip I brought with me. Voila! It worked...in spades! Btw, I used a saliva as a patch lube and had no fouling issues for the remaining 14 shots. Also, I used Wano Scheutzen FFFg powder @ 55rgr. (vol.) and had no trouble reaching the 70 yd. targets.
