Anyone ever use Hornady Brass and/or Horn 117 SST in the Bob?

I just bought a 257 Bob and found a decent deal on loaded 257 Bob with 117 Horn SST bullets. I've never shot SST bullets but it looks like I can get loaded ammo for the same price as buying empty casings. I could shoot them as is or pull the bullets and dream up my own loads.

Those 117 SST's will do anything the 257 Roberts is capable of.

Yes at Bob speeds they will work just fine. I'd shoot the loaded without hesitation and then roll your own
