I have a 7stw built on stiller action in a mcmillan stock with seekins bottom metal and ai cip mags. This seems like about a big an oal mag as I could get. Problem for me, simplicity. I now want to take the gun in the field and i'm thinking, 3.85 oal is enough, but i don't like the hassle and jutting out of a mag system. I kinda want to go to a blind mag or hinged floorplate? Previously I had a hinged floorplate with a wyatt extended box but it seemed flimsy, as one time i opened it and everything popped out. Not fun in the field. Any ideas? Nothings perfect? I'd hire a smith here to do the work. I normally don't fiddle. Thanks.
