I was at the range last fall there was a guy there with a 450 marlin. He was trying out the leverelvolution . He did have problems with the ammo it would jam coming out of the feed tube.The flat points that he feed consistantly but when loaded with the levers they would jam.He kept trying to cycle them through and after about 30rds they started feeding alright. Dont know why it was doing it but it was a brand new gun .
More than likely there was a burr at the end of the feeding tube and with a little use it probably broke loose. I seen this one other time with an 1895G and it only lasted a short time.
