As far as the feeding problems go.....How do the guys using the wssm based rounds get around this?
Actually, I have used a 450 Bushmaster magazine in my 300 OSSM. They get around the clearance necessary to accommodate the larger diameter bolt and bolt carrier by cutting the upper part of the mag latch hole higher, making the mag set about 1/8-3/16 inch lower. The amount needed to clear the lips. Picks 'em up smooth as silk. They also notch the front and rear mag walls down a little bit like the 450b does with just the front.
Bigger bolt carrier looks like this:
