Anyone reloading 500SW for Bighorn Armory Spikedriver

[leeelmer]

Just seeing if anyone owns and reloads for their Bighorn Armory Spikedriver in 500S&W?
I have one coming, and plan on mostly reloading 350gr hollow points, got a pile of Hornady XTP here and a bunch of Campro cheep plinkers in 350gr
I downloaded Bighorns reloading manual, so I have a starting point, just seeing if you guys have found anything that has worked well(or didn't work at all)
Thanks

Since when does Campro make a 50 cal bullet for 500 mag? Because I'd definitely be interested. They don't list anything on their website.

Mine was best with CFE BLK. Of the many I have tried, the 300 FTX shot the best for jacketed far better than the 350. The Lee 440 shoots just as well the FTX with 4759.
