Shootemup, and anyone else who is not a member of FCSA.
I highly recommend that you join the Fifty Caliber Shooting Assoc. It is only 40 bucks a year and your get quarterly magazine to read along with the forum. Yes they do have 1000 yrd matches and I do not think I will be able to attend one for years, but the knowledge that you will find in the forum is well more than you will get anywhere else.
Check out the site at www.fcsa.org and go to the guest forums. Though be forewarned that many of the guys that are members will not give out their loading info at the guest forum. I can tell you, it is the best 40 bucks I spent so far.
And Shootemup, I have no experience with this ammo. But I would do some serious checking on it. There has been some forien ammo in the past that was loaded dangerously hot in the past. Something from the domino republic the way I remember it. Course, I have a tight neck/chamber and have to hand load all of my ammo.
