Or powerbelt, 295 copper HP with 90 grns pyrodex powder.
pellets don't burn as clean

I've killed 2 bucks and a bear with this setup.
Another option is the 348 copper HP with 100-120 grains, that penetrates very well.
150 grains of powder will kick like a mule and not fly straight

The aerotip bullets are too fragile in my opinion.
