.500 Linebaugh is based on the .348 case, is it not? Why not just go a bit longer and chamber .50/70 for the 2 3/4" case, or maybe a shortened .50Alaskan - or full length Alaskan at 2.090" trimmed, using Starline brass?
That will give you the ballistics you want at even lower pressures.
According to my 2004 Hodgdon Annual Manual, page 111, the .50 Alaskan, with a 22" bl. and Starline brass, will get up to:
:2,089fps w/435gr. LFN w/GC @ 35,500CUP and 1,912fps at only 26,100CUP
:1,940fps w/450gr. Barnes FP @ 35,300CUP and 1,772fps @ 28,600CUP
:1,854fps w/500gr. JFP @ 34,500CUP or 1,719fps @ 28,600CUP
:1,852fps w/525gr. LFN w/GC @ 34,800LUP and 1,724fps @ 27,300LUP
Sounds like a winner to me.
The thing is, I just didn't think of anything else. I am a big bore handgun shooter/hunter so I think I just naturally thought of a handgun cartridge. For example, I have a Marlin 1894 in .44 mag, and I have never had to shoot anything twice with it.
So when I became curious/obsessed with double rifles, I thought the barrels have to have really big holes, and at the same time something that is fun to shoot. With regard to 50-70 or 50 Alaskan, I don't handload, yet, and Buffalo Bore makes the exact ammo I want. Finally, I already purchased the ammo and sent it to Aaron who already has the stock blank. We're just waiting on the barrels.
