44 mag load

[madmike]

I just bought a .429 255 grain lee mold for my new 44 but i can't find a load recipe any where for a 255 grain bullet i plan on using unique anyone have a pet load they would like to share or maybe a safe starting point:confused: Thanks in advance

I'd try around 9.5 grains for 1050ish, depending on bbl length.

Harsh fact: Molds seldom drop bullets at their stated (nominal) weight, they are generally heavier, sometimes lighter. So starting data for bullets of 240 to 270 grains would be safe starting points for a "255" grain bullet. That is why we always stress starting well below max data. This point is stated many times in every loading manual.

[madmike]

so i can take a starting load for even a jacketed bullet of heavier load and just keep it under 1000 ft per sec:mrgreen:

Jacketed bullets commonly raise pressures. The general "rule of thumb" is that jacketed bullet data is safe for cast bullets of the same weight. The converse is NOT true. Here is Alliant pressure tested data for 240 gr cast bullet:

My old 45th edition Lyman book gives data for a 250 gr with gas check. #429244.
Unique starts with 7gr for 819fps. Max load at 12gr for 1200fps. That's from a 6 ½ barrel S&W 29.
I've shot 8gr of Unique behind a 240 gr SWC for 940 fps in my Colt 6”. That kicks enough to make my tennis elbow flare up after a couple hundred rounds. So I'd say anywhere from 7 to 11 gr. Then if you want more power get some slow powder.

more power go to 2400, want still more? h-110/296
want still more buy a 445 supermag.

Depends upon what u want to do w/it.

24 gr IMR 4227, 429244, ww brass, WLP primers. Great in a 10.5" SBH. OK in my 4 5/8" SBH. Killed a few deer at 50 to 155 yds. manageable recoil compared to 296, H110 and 2400.

Thanks alot for all the info i load some up tonight :Fire:

Lotta folks gripe about it being dirty, but I am more than a little partial to 2400. I drop Elmer Keith's old hot special load of 18.5 under the RCBS 250 K.....cloverleaves at 25 and it doesn't give you wrist dropsy either!

[runfiverun]

i shoot 19,5 in the 44mag and 45 colt out of my 92's and wessons it's about all i want
and i think i like it out of the pistol better.

I can't believe no one mentioned the reloaders reference software put together by one of the esteemed members of this website. This is some great software for a serious reloader. Lots of data and space to keep up with all your supplies.
Anybody remember the link to download??:-D
