Is it my Dissy or is hollows not a round for ARs?the only way I can get my Diss to fire them is to grab the mag and put forward pressure on the mag.otherwise when feeding the round it is jammed on the ramp pushing the bullet into the case.the feed ramps are nice and smooth looking.and other than the suck olympic green tip and these it is a flawless shooter.the ammo in question is wally worlds 45 grain, 40 rd box ammo.I don't need to use hollows it was a cheap buy.

Do you have the enhanced feedramps or not?

That stuff is winchester 45 grain varmit rounds right? 40rds to a pack.

have you tried using different magazines first, maybe mags with different followers as well??

I have run those bullets through many guns, and never had that happen. That is what leads me to a mag problem.

no enhanced ramps its not M4 if thats what you mean.the ramp does not continue into the lower and I even bought 5 new D&H magazines and same thing.I run any other ammo and literally 500 rounds and not a single failure

This would be one of the few times where extended ramps would be a recommendation.
