I don't have much trouble loading the 300 grain Expander MZ in my Savage 10ML-II with the supplied MMP sabot. They require firm pressure, but it's not excessive. T/C bores are notoriously tight, so if you shoot a T/C, your mileage may vary. The 300 grainer is the most accurate in my Savage, they always seem to expand well because the exit holes are always 1" or bigger depending on where it is, and I have yet to recover one because they always go through. After all the negative stories I read, I wouldn't hunt with a Powerbelt if the company sent them to me for free (I'd probably plink with them, though...
).
