.44 300gr Sierra and Unique?

I have a current Sierra book and they don't have any listings for unique or bullseye, only the usual magnum powders like h110, aa#9, 4227, 2400 ect.
OlderAlliant books show 300 gr ftp Hornady bullets with bullseye 7.5 gr 955 fps. @ 1.600"
Unique 8.3 955 fps both loads at 34,800 PSI. Alliant only lists max charges, reduce by 10% for starting loads. They also show loads for 310 lead SWC. Found the data on castpics.net.

Personally, I'd stick with the bullet mfg.'s info...

I've always believed, you should stick with the data from the bullet mfg. you are using...

That's definitely a safe philosophy. I'm glad there are those willing to push the envelope though. Think where we'd be without Elmer Keith.

Keith was one drop in a huge bucket... If it wasn't Keith thinking things up, there would always be some one who would of. Cartridge design didn't stop when he passed on!

Personally, I think Ackley and several others were more important, to get where we are today...

Myself, I would think Unique a bit fast for a slug that heavy. It should work just fine though. I'd probably give IMR4227 a whirl with a 300gr

I know where I wouldn’t want to be: standing beside him when one of his guns exploded!

Think where we would be without Elmer Keith.......well, we would be down a few stories. For anything else....ya just don't know. yes, he was instrumental in developing the .44 magnum. If we assume that it would not have happened without him, we would be wrong. Any number of things might have happened that would lead to that same end. Give credit to Keith but not more than he deserves. Personally, I think that his "Keith bullet" is more important.

I'd like to see the list of the "bunch" of guns he blew up...

I've read just about everything he dictated, I never read about a "bunch"... I think you would find that, that is just a myth...

Modern Reloading 2nd ed has the same powders/charge weights/velocities and psi as your Alliant books for the 300 gr XTP.

Stay safe
