First off, welcome to the site! Glad to have you aboard.
You're missing that this is posted in the Site Information board and not the Vintage Centerfire Rifles board where people that can halp will actually read it. I've moved it for ya.
Sounds like someone disassembled and reassembled the rifle at some point and wound up the magazine spring a little too much. Mad Dog and a few others will be along shortly and can tell you how to fix it.
