Back in the 60's, when P14 Enfield actions were available and quite reasonable in price, I had rifles built in .375, .416, .500 .505 and .577 caliber, all but the last based on a .460 Weatherby case shortened to 2.500". They were all built on P14 Enfield actions.
They achieved respectively .375 H&H, .416 Rigby, .500 Jeffrey. .505 Gibbs and .577 Nitro Express levels of performance. I took the .505 to Africa on three trips and took rhino, elephant, and Cape buffalo with it. It never failed me.
The actions were modified by removing the rear sight "ears", straightening the trigger guard and shortening the magazine and converting to cock on opening with a Dayton Traister kit. They alll functioned perfectly and continue to do so today.
This is my .505, with three of my wildcat catridges standing in front of it: the .450 C&W, which is a rimmed .450 Watts intended for a double rifle, which I had built, the .505 SRE (Short Range Express) and the .577 VSRE (Very Short Range Express). The other photo is of my record book black rhino, which I took with the .505 SRE in 1971 in Kenya.
