I used "Shooter" on my phone for the last post. There is a bit of difference.

There is also a bit difference using the 357 (same bullet) in my Marlin.

Again: Is the 30 cal carbine the best for deer size animals? NO, I prefer my 257 Roberts, but at hand gun range it looses nothing to the 357 Revolver.

I don't hunt with pistols either.
