Thread: BSA Hunter 222 rebarrel to PPC

It isn't a difficult task to alter a magazine for another cartridge either lengthways or widthways PROVIDING that your floorplate is of suficient size to cover the different sized mag.
I have just lengthened a Zastava M85 magazine to accomadate a lengthened Grendel cartridge by cutting the rear of and making a new back from sheet steel so to get a bit of width just cut it in half front and rear and weld in a strip. You may even be able to get away with just cutting the rear and keeping the locating notch on the front and spreading the front walls slightly then bending it again just in front of where the shoulder will be then welding a strip in the rear. Just make sure it is smooth on the inside so the cartridge has nothing to stop its free movment. I believe that the shape of the case, ie shoulder width and base width are important to get the best loading characteristics. Look at the cartridge you want to use and measure 1 1/2 times the shoulder and the case head and look to have the magazine at these dimensions at these junction points.
