I swapped a 223 barrel out for a 204. I can't get the 204 to feed from the magazine, this is a staggered magazine. I think I saw the fix on this some time back, but have not been able to locate it.

Is is there a source for blind magazines any where? I have one of the early long action 223's. I am wondering if I can get soome of heavy 223 bullets seated out to feed from the magazine. Anyone else tried this.
