One thing I learned while trying to get my marauder to shoot accurately is how much bore diameters vary from barrel to barrel.I ordered a marmot militia barrel after giving up on the original barrel. Well right before I received my new barrel I decided to check bore diameter with pin gages and found the barrel to be .218 in diameter. I order the largest pellets I could find which were H&N FTT in 5.55 and it shot very accurately. Anyway when I received my new barrel it measured .209 in diameter. It fouled pretty quickly. I believe alot of the problem with fouling is using pellet that are too big for your barrel. Try measuring your bore size and buy pellets slightly larger than your bore diameter, I think you will find that it fouls less. Just my experience for what its worth.
