I have used round balls with patches in the past and did take a deer at 70yrds with it, there was a hole 1/2" in and 1/2" out. I don't have the confidence with the accuracy and killing power on a moose at longer ranges. I know, I know, back in the day they were all that you needed to kill gophers and Grizzlies
I think I will hunt with the 250gr SST if the accuracy is good at the range, and hopefully test them on a bear this spring
