I live in New Hampshire and usually hunt with my 54 cal round Ball J Browning Mountain Rifle but this rifle is heavy to haul around the woods but does a great job putting deer down. But at 72 and some bone problems I want to use my much lighter 45 cal round ball rifle for the hunt this year. I know the 45 ball is lighter then the 54 but I believe a 45 with 60 grains of FFF will do the job. I'm still a good shot and I know shot placement is important. Most shots are less then 75 yards. Does anyone hunt with a 45 round ball and 60 grain FFF load and what are the results? Thanks, Steve
