    I recently bought a Mark V 300WTBY and put a swaroski 4-12 BDC scope on it and I have been shooting some reloads that I reloaded in the early 90's, I used to have a german markv that I shot for deer with a load of 77.5grs of IMR4831 and 150 gr speer ballistic tip. Looking for a new load/bullet that will be used for deer and coyotes and at ranges up to 600 yrds, any ideas?

    Try the Bergers, Hornady A-Max, or Nosler BT's. All have good BCs and do well terminally. H1000 all the way!!!

    Hey, check out my load development for my 300 weatherby. Let me know if you have any quesitons... I tried H4831 and IMR7828 and H4831 shot better. I may also add I have heard good results with RL22 and RL25. I havent had the chance to test however...

    I shoot 80.0 7828 with a 210 Berger, very hot load approach with caution. I get 2980-3000 fps out of a 25.5 in. barrel.
