welcome diesel dog, you could do a search and you might get some ideas, a friend of mine has a encore in 209X50, he bought his used and we cannot get sabots to load w/o it getting scary, i mean you have to stand on the ramrod[:-], so we used some advice on one of these post about running a maxi-ball or a buffalo ball down the barrel and then running it back out and checking it, well we did and as soon as i can post pic from digital camera i will, but this bullet looks terrible, we have scrubbed his barrel with everything we could think of to no avail, i think this one is going to have to make the trip back to t/c. and i'm not bashing t/c i have the same gun/barrel and have no problems i also have a black diamond, both are great shooters, as are all the t/c products i have but his barrel really has us scratching our heads[&o]
