I wanted to share the final results of this unique build. DPCD is the master gunsmith for the barrel and action work. Started life as a stripped Siamese Mauser action I picked up on the cheap. DPCD took on the challenge of trying to turn this into a 500 Smith and Wesson Mag bolt action rifle and I would call it a success. The gun is throwing 385gr Maker at 1825 fps with an 18" Douglas barrel. The theme for this gun as you can see was a safari classic look. The wood I finished and inlet/bed myself with tru oil on a fancy grade myrtle.
Those decelerator recoil pads really do wonders but the recoil is not bad at all. No more than say a 3006 maybe 30-30 even. Bit more pop that push. Think slug gun vs rifle.
Starline makes the 45 raptor brass and they made batch late last year so it is floating around out there. Starline has it direct right now and I got more recently in 100rd bags from Crate Holdings
