I've been doing my homework learning about Doubles for a year or two and I'm debating which caliber for mine. So I thought I would test the waters from this august group.
The rifle will be for animals other than elephant so I'm going to stay under a .50. I'm looking at the following"
.450/400 NE 3"
.450 NE 3 1/4"
Opinions and thoughts? Pro's and cons?
