Anyone w/Quickload? .50 BMG Question

[#40Fan]

Looking for a load for a 440 grain bullet. I have H50, some surplus powder (WC-872 is what I'm thinking it is...not near to check right now) and hopefully, if it will work, RL-26. I'd like to see somewhere around the 4k fps mark!

Anyone willing to run some numbers to see where a good starting point with any of those powders would be?

Need anything else from me, let me know.

I only have a limited amount of material I'm making the bullets from to be used for a brief science experiment and I'd like to find a load rather quickly.

Thanks.

You can download Gordons reloading tool. It may help

Barrel length?
What bullet?

440gr? Sounds like a light varmint load! Are they solid copper(or other) monolithic? That could skew the pressure curve for those QL calculations.

You cannot be around 4,000fps, at most 3700 fps from 43" barrel

30" barrel. Homemade solid copper bullet.
