I am currently shooting hornady great plains 385 grain bullets with 75 grains pyrodex RS from my traditional .50 cal Hawkens percussion cap rifle. This load works great for hunting white tail.

I am limited to using 90 grains or less of powder per the owners manual.

I want to switch to copper/non-toxic bullets for this years hunting season, would like to ask for recommendations for copper bullets that will effectively take down whitetail deer with under 100 grains of powder.

Thanks in advance
