Fifty,
The 221 is a factory 700 classic restocked with a Rem factory camo tupperware stock in ADL configuration.Have tried many different bullets-35 Bergers -40&50 NBT-40,50,&55 V-Max.All give same problems.When mag is loaded with 2 or more rounds the cartridges pop out of the mag prematurely as the bolt starts forward.The follower spring seems a logical culprit,but is original component on this rifle.I'm afraid this round may simply be incompatible with being fed from magazine.Hope not because little rifle shoots lights out with almost every load I've tried and is great in it's role as my small varmint,crow,truck gun.Thanks for the suggestions and any advise.
