I dont have trouble after one shot, but it does get harder to push a saboted bullet down the barrel the more shots you make, it usually gets pretty tough by the 5th shot or so. I changed to the Powerbelt bullets, and got the same or better accuracy, and they push down the barrel much easier. I love mine and use it for lots of my hunting, both muzzleloader and rife. You cant go wrong with the Encore.
