Powerbelts are a good choice for a lot of us; and for some of us they
are a bad choice. It's the nature of the beast; human beast that is.
As for ease of loading, for most ML's, they work great. Some folks
say the gas seal will blowout with magnum powder charges. As for
me they work great. I shoot a 45cal and a 50cal.. the 50 will shoot
PB's ok but I have a lot of fliers. But the 45cal shoots powerbelts
with astounding accuracy. My load combo. is 2-50gr. 777 pellets
195gr. aero-tip powerbelt and remington 209 primer. Good luck hope you will enjoy your ML.
