I got the replacement Avenge-x classic today. Spent the past 5 hours cleaning the barrel off and on. The interior finish of the barrel is way better than the original. Still had plenty of crude in the bore but after each layer was removed the finish would shine more and more. The end of the barrel looked exactly like Randy described EDM wire cutting. Where the transfer port enters the chamber is clear of the leade. It didn't shave any lead from the pellet skirt when chambered. I got the scope mounted and cheek rest adjusted. I'm gonna leave the rest of the gun as received except for gassing the cylinder/tank. Tomorrow is a high setting over the region so shouldn't be any winds. High's in the low 80's. The last target I shot is still stapled to the target backer so I'll have a direct comparison with the returned gun. It'll be a poor day for deer hunting but really great for bull's eye hunting.
