RE: New Gun, What is it?
Suggested loads -
Being a .50 caliber start it with 70 grains of 2f powder and work up 10 grains at a time for the best possible group. Most of my CVA's tune in around 80-85 grains of powder.
With a conical, I do the same thing. Start them at 70 grains and work up. Most of them tune in around 80 grains. Since all rifles are different only your rifle will be able to be the final judge in that matter. One thing I will say for the CVA traditional rifles, they are normally excellent shooters. I have had a lot of them and never had a bad shooter in the bunch.
After you get what you feel is a good load, then when you have time you can experiment with different powders. Some of the .50 calibers do like a 3f powders as well.
