Long story short have a lot of 5744 and almost out of h4895.

I want a reduced load for 8mm, 30-06, 6.5x55, 45-70 and maybe others using common jacketed bullets, 196, 168, 150 and 405 respectively.

I see on web some say accurate gave them info. Fill case to where bullets would seat, weight and x by .4.

I don't see anything published. Can anyone verify this. I don't want a pfft with partially burned powder or worse.

I think that's your answer right there... I would contact Accurate. AA5744, when compared to H4895, is much faster, and would already produce lower velocities, likely within published loading data, much like IMR/H4198.

I have used AA5744 in the .45-70, at Trapdoor levels, and it worked very well, but I don't know if that would translate to bottleneck, smaller bore cartridges.
 
Hopefully, you have better luck than I did. I reached out to them via their website back in November with a similar question and got told "We do not have or recommend a simple formula for loading 5744, it would need to have tested data for it.".

I did some further digging and found a reference to reduced loads using 5744 in Appendix 2 of the second edition of "Dangerous-Game Rifles" by Terry Wieland. The formula was as you describe and purports to be for any caliber. I tested it in a .400 Jeffrey Nitro Express and 41 grains behind a 210 gr Hornady JHP yielded about1900 fps.
 
Speer has/had a lot of 5744 data. The Western 8.0 online PDF should have plenty.
 
Thx for all the info. Folks disregard what I may have asked and stick to published data. If I find some data I will post from reliable sources and not internet discussions.

Which is why many of us suggested you go to the source... even if it winds up being the answer you don't want to hear.

No I want the right answer and I was unsure if there was a source of this info.

Other than Hodgdon's H4895 reduced load formula I've never encountered reduced load data published by a "reliable" source. However, I've seen several older references on the web for Blue Dot and Red Dot reduced loads. One of my pet 30-06 loads using IMR4198 came from an ancient American Rifleman article by Ed Matunas. Post #5 gives another unofficial source for 5744 loads.

I can't recommend any of them to you.

I just checked the Lyman 50th, and they have load data for 5744 in those calibers, but only for lead pellets....
I also checked the Western Powders Handloading Guide edition 8.0, and it is hit and miss for those specified calibers...

May or may not help you....good luck...

holding me some h4895 pic they ever receive any.

That's probably your answer, all else being equal. There is also generic reduced data for low velocity loads using powders like Unique and possibly 2400, et al... but I'm not a big fan of those, and that's only with cast bullets.
 
Just got this answer to my question I sent direct to the powder manufacturer. Impressive I got an answer in 10 minutes. He sent a word doc too that shows multiple calibers in it.

This data is valid for both cast and jacketed bullets and should work very well for what you are wanting
