721 Magazine Fix

[7RUM]

I have a 220 Swift built on a 721. Problem is, sometimes when chambering a round from the magazine the rim of the round I'm trying to chamber gets hung up on the one under it causing a jam. Is this a problem I have to live with because of the semi-rimmed case? This is my first Swift and have no experience with rimmed cases in a box magazine.

I don't believe you have a prob with the magazine, when you load each round try making sure they are pushed to the rear of the magazine, that should put the rim of the upper cartridge just ahead of the cartridge below it...give it a try
