Hi all. I recently bought a lyman gpr. I've only had the opurtunity to take it out a couple of times for shooting. Anyway to the point. It seems after every 2-3 shots the ball gets hard to ram down the barrel. I can't tell you the patch size,but it's a .50 rifle using .490 swaged balls. If i can get past the first 6 inches or so down the barrel it loads fine. Is this a case of 'braking in the barrel',or does it sound like something's wrong? Should i have to swab the barrell that often? I'm using 80 grains of fff goex. I tried using a smaller load of 60 grains,to reduce fouling,but it doesn't seem tomatter. I'm sorry if my post is a bit jumbled ,or hard to understand. If anyone has any advice i'd be gratefull.
