CAN you get some interferance fit? Yes, but you need to get a reamer, and re-do the chamber for a deeper setting.
The theory of operation at play here is that the bolt baffle(piece behind the bolt head) plugs the escape route and the 2 ports on the side of the reciever vent the gas, if there is a case seperation. Then there is also the rear baffle to add another layer of facial protection.
I have blown-up cases on: Ruger's, Savage's, Marlin's, Remy's. The Savage's seem to keep things the most pleasant when a seperation occurs. I've had a 270 & 264WM come apart, with little fanfare.
