My first M. L. was a CVA Hunterbolt it came with 2 barrels 45 & 50 cal.
I started out with the 45 cal. barrel. The biggest disadvantage was finding 45 cal bullets in my area very few places carry them If they did have them the only choice was PowerBelts. They are a very easy loading & accurate bullet.I didn't know of the down falls of a PowerBelt then. I admit I over powered them using 100 gr. of 777. Needless to say I lost my first M.L. deer. If you read this forum very much you probably know about Powerbelts. Some people love them. Some people hate them. I now only shoot 50 cal. There is a endless choice of 50 cal. bullets.
