If were to build myself a dangerous game rifle it would have the following features.

Bolt action

Push feed design. I choose this for two reasons. #1 I have tried to get a push feed to not feed and I find them every bit as reliable as a controled round feed. #2. If, for some stupid reason, I empty the gun and I am still in danger but not yet dead I can drop a round and chamber it with our having to push it into the magazine first.

Cartridge would likely be either a 458 Lott or a 470 Capstick.

Barrel length would be 24 inches.

Iron sights would be a Marbles universal for the rear with the large peep apreture and front sight would be a hooded and banded ramp with a white bead sight.

Metal finish would be fine bead blasted and parkerized.

Scope would be a 1-5X42 mounted with Talley QR rings and bases.

Stock would definetly be a nicely figured walnut. Hand rubbed oil satin finish or permalyn satin finish. Shaped to fit me with a roll over cheek piece & Pachmyer decelerator pad
