Re: I finally got to shoot my new 300 Ultra
Txhunter, Grizz is going to be between h870 and H50BMG in burning rate but have a curved pressure curve like big boy. It is too slow for the 200 grain bullet in the 300 Ultra. They got 3100 fps from a 200 grain bullet with only 53,000 psi though. I think it may be perfect for the 240 MK. One of there tech guys is getting 3500 + with a 180 barns from a 26" barrel 30-378 with no pressure signs what so ever. It will cost about the same as Magnum powder costs. It should be good stuff. Will be out this spring. I am a full time student and I work at a gun shop 4 days a week. It pays for toys and gets me good contacts. I had to promise not to give any to a customer, and say nice things about their magnum powder to get a couple of pounds early.
Working to improve hit probability.
