Cleaning patches should be softer, and looser weaved, than the patch you wrap around the ball. Use water, spit, or windex, or any water and soap combination to soak lightly the cleaning patch.
I recommend cleaning after each shot. That way, you are not guessing when you are going to find it difficult to seat the PRB down on the powder, or fail to do so. :shocked2: It also provides the most consistent accuracy, as your barrel is in the same condition for each shot.
You will need a cleaning jag, in addition to the loading jag that comes on the ramrod of your gun. I encourage you to buy a solid range rod, with muzzle protector( Made of brass, or nylon) to use to both clean and load the gun. Leave the gun's ramrod for loading the gun in the field. You won't find yourself shooting that many rounds in the field that you need to stop and clean the gun.( Unless, perhaps, you consider it sport to shoot squirrels out of trees with a .54 cal. RB!) :rotf:
Find a target load that puts the balls in small groups off a rest at 50 yds. 70 grains of FFg powder is about where most of these Lyman rifles shoot well. Then, for deer hunting, find a hotter load-say 90 grains of FFg- to flatten the trajectory a bit more. Most deer are shot well under 50 yards, but on the occasion that you have a longer shot, the hotter load will allow you to hold dead center on the deer's chest, and still hit it out to about 120 yards. That is a very long shot with open sights. :shocked2:
