Need help reloading 50 alaskan with 50 bmg bullets

[shaun1921]

I just bought a SSK .50 Alaskan 20" Encore barrel that is threaded for my Gemtech Storm front 50 BMG suppressor. I now need to start hand loading ammo. I want to load 50 BMG bullets in the 650-800 grain range and have them moving around 1050 FPS to avoid the sonic boom. I plan mostly on plinking but it is legal in my state to hunt with a supperssor so I might want to try taking a deer at some point. I have not reloaded in years and do not know where to start. If anyone can share powder / bullet recommendations I would greatly appreciate it.

What's the barrel twist?

[shaun1921]

the barrel twist is 1:10 SSK said it would be the best choice

Anyway of measuring your available overall length?

I thought Quickload had 50 Alaskan setup as a cartridge, only has 450 Alaskan.

If you can give me your OAL, cartridge length, water capacity of the case, and the Max PSI you want to stick with I'll run Quickload on it.

Although JD @ SSK would undoubtedly be the best source of data.

16" 1/10 twist
750 AMAX
3.920" OAL
34.0 gr RE7

mean vel: 1057
SD: 7fps

kicks like a damn mule! 6 rounds today and my shoulder is killing me. Think I'll replace the factory TC pad with a limbsaver. Only shot at 50 yards, but it was one huge ragged hole. Hopefully the can will tame the blast once it gets here.

I pulled one of the 750's out of the berm yesterday. The mud was a little softer than tissue, but the tip still bent enough to cause it to tumble. I won't have the can for a few more months, but I'm still going to take it hunting over the next few weeks. I should be able to put at least one doe down (20:1 doe:buck ratio)
