What is the prefered hunting bullets in 45 cal, looking for it to be easy to load, and accurate.

Powerbelts, Barnes, Hornady XTP or something else, what grain bullet, heavy for the extra energy or light for flat shooting, not a lot of choices for the 45 available in the local retail stores

I currently shoot 195 grain Powerbelts with 100 grains of pyrodex and it shoots well

Wondering if the track record is good on Powerbelts, its a one shot deal
