I purchased a semi auto marauder a few weeks ago and have been enjoying it since. It's got a bunch of squirrels and starlings under its belt and loves JSB Hades and regular JSB 16 grain. Shoots others well but not hole in hole at 35 yards like the ones mentioned. But I think pellet testing is what caused my problem. I think heavier pellets and slugs caused the mag to rotate slower than the bolt cycles which caused the bolt to impact and damage the pellet divider tabs in the mags. Has anyone else experienced this issue? I'm thinking about making a 1.5 mm thick plate to overlay the mag internal so bolt impacts can't damage the plastic divider. I've contacted Benjamin crosman customer service and they've agreed to send a replacement and when it arrives I'll begin modifying this one to fit the plate. Hoping that will solve it but I'm open to any and all suggestions if someone knows a better or easier way. Or if you think I'm wrong about what's happening to cause the damage and see it differently that can be helpful too. Thanks for any help offered. And It's not perfect but I hate the factory finish they put on rifles in the marauder family price range and quickly strip, sand, and refinish any rifle I buy before final setup if you're wondering why it looks different.
