How do you figure that when 2400 will give you the same energy and velocity with similar bullet weights as either of the powders you mentioned? What can those powders do that 2400 cannot?


2400 does not do that, in my experience, in any of the magnum revolver cartridges I've used it in (357, 44, 45C, 454). I've always been able to reach higher velocity with H110.

For mild to mid-range loads, Unique will give the same velocity as 2400, but with less flash and less recoil.

2400 is a popular old powder, and it meters well, but I haven't found any loads that can't be done better with either H110 or Unique. Since I'm not a guy to own just one powder, 2400 doesn't seem to have any clear advantages, in my experience.


Well somebody should tell Lyman that 2400 will not do that because their loading manuals have been saying that it will for the past 50 years or more, and my chronograph says it will, regardless of your experience. Unique will not come close to the same velocities as 2400 and anyone who has any experience at all knows that.

I am going to continue to try to answer leomort's questions, and I shall ignore the attempts to deflect this thread into what loads you like or what your experience has been.
