I love the 450-400 3" cartridge and I like my Chapuis SxS it's chambered in. I think it would be very limiting as a one rifle Batterry on Safari. I can't shoot it much past 150mm even with the Leopold VX6i scope. On smaller plains game I think it would be a real handicap. A 375 with a good scope is an easy 300m rifle.

I love to hunt with the the double but I Hate passing up taking great trophies at longer ranges just to be pure. The hunt comes first, the tool enhances the hunt for me but does not define it?

Just my 2 cents.

Life is not to short to hunt with an ugly rifle, if all you have access to is an ugly rifle go and enjoy the hunt anyways.

Of course a period SxS best sidelock does not hurt the experience .
