Loading 44 mag for 1440fps

I am setting up a test bed using a Thompson Contender frame. I need to fire 230 grains at 1440fps with the min. variation in speed. I will be buying a new custom barrel. Is there a way to determine the best length?

I've been loading "Elmer's Baby" for a long time, and I've never run across 230 grain .44 bullets; but it is also that long experience which tells me that there are so many components for this cartridge that I may not have seen them all yet!

From the tone of your post I'm betting you will have a chronograph handy for your experiments, so it's a simple matter of selecting a slow powder like H110 or W296, commencing with the "starting loads", and then easing your way up to the velocity you are trying to attain- watching for pressure signs along the way. I believe I would use the 14" Contender if I were you, although you should have no trouble getting 1440 fps from the 10" tube, either.

The following should help you get started, I hope-

Please let us know how it all works out. I am always willing to learn something new about this fine cartridge.

It can only be ensured by instinct, sharpened by thought practicing the stroke so often that at the crisis it is as natural as a reflex.” ~ T. E. Lawrence

S/b 240

Can't type. I am using Remington 240 Grain Semi-Jacketed Hollow Points.

Thanks for the advice and I will follow the link.
