I have a Stevens 200 Centerfeed that was a .223 but have since swapped out the barrel to 6x47. Once I get over 75 grains with hunting bullet the start eating the powder room from seating them deep enough to use the magazine let alone a VLD style or Mono Metal bullets. Well I had my rifle apart the other day and noticed that little black plug at the back of the mag, wondering what kind of can of worms I'd be getting into if I got the Dremel out and worked on it?

My barrel twist is fast enough to stabalize 85-95 grains in theory and I'd like to play around with some heavy bullets.
