Just starting to play with mine. It has what I'd call a G1S stock on it, good one side, other is plain. The nice side has some fiddleback though. I bought it cuz I just couldn't find anything else that looked practical to play with, that was a little out of the mainstream cartridges. There is load info around on it for a number of bullets, but a lot of it is scattered.As I get to working with it I'll post what I have tried that works.I have found 2 good pcs of info for it so far,other than Hornady, mostly 400gr stuff, some cast bullet stuff with Trailboss and AA5744, One fella is working with the 300 Horn at present and IMR4831, there is a post on here from 2006 from 470Evans on it with IMR4064 also. There are a few who have done Trailboss and 210 Horn.
I think there is really a lot of potential for this cartridge and gun to become something fun for a lot of people to play with as the data gets collated a bit.
