Well I've just started with the 444 and as far as bullet weight, that's yet to be settled on. I've loaded about 20 rounds with 180 HP's, 20 each of 2 cast lead 240 grs, some cast 290 gr FNGC(Lyman 429640) and some 350 gr FNGC.(this is an older Lyman design no longer produced) I did decide to experiment with one load using 748 and that was a remington JHP starting with 50 grains, this based on looking at published loads using AA2230. I like the way 748 meters and it's useful in the 45/70 in various charge weights with 300 to 420 grain bullets. I've loaded the 420's from 50 to 58 grains as well as the 300's. I settled on a std load for the 420's at 50 grains. Fast enough to do the job (about 1600 fps), but not hard on your shoulder. Just looking for the same with the 444, I'm not looking to set speed records, just a middle of the road load that's fast enough to do the job, but still fun to shoot. When we go out to shoot, we usually burn up at least 500 rds total in several calibers. The gun is a Winchester 94AE with the 20" bbl. Thanks for the input.Its easy to double post, just remember that most of us hit the “Today’s Posts” button so we’ll see the post no matter which forum its in.
You didn’t mention bullet weight.
In my 17.5” Winchester Timber Carbine I use 57.0 grains of Winchester 748 behind the 240-grain bulk Remington bullets for our light framed deer and pigs. This load chronographs 1,553 fps from the short barrel and will penetrate very well with good expansion. It delivers quite a fire ball in the short ported barrel.
This load loses a good 500 fps when compared to a 22” barrel.
Looking through my load data I have no good load information using heavier bullets with Winchester 748. I much prefer Hodgdon 4198 with the heavier bullets for use in my short barrel. Either 4198 gives me a tongue of flame and orange spouts up the ports which is much easier to see through in dim light.
I have loaded with IMR 4198, but I use 748 with my 45/70, 30-06 & 30-30's. I buy 748 in bulk for the others, just trying to keep my inventory of different powders to a minimum. 748 is between 4198 and 4895, both of which are shown in many loadings. It's right there with AA2230 in the burn rate charts, which is also shown in several load manuals for 444 loads. Thanks for the input, it's always appreciated.It's not listed in any of my usual/trusted sources for reloading data. It would probably work ok, since it appears it's a little on the slow side for the .444.
I would save what you have for the .45-70 and use something like H4198 or H322 if I were you.
That's a REALLY light load in a 45/70 even under a 300 gr HP. I would be concerned about pressure spikes from it not filling the case. As for it being safe in a Sharps ? Don't know. The Marlin will stand higher pressures, but I'd also be leary of upping loads in a T/C. I've run 300 gr HP's with up to 57 grs 748 with a Winchester Large Rifle Magnum primer and they're completely safe in a Browning 86. My Pedersoli Sharps digests my middle of the road loads I run through the Browning 86. There's data out there in the books for 748, it's how I started with it in my 86 Browning. I use it for 300 to 420 gr lead bullets. For the 500 grainers I use IMR4895, AA 2015, IMR4198 and AA2495.I have some 45-70 rds loaded with 300gn JHP, 39.5gn W748 powder, CCI 200 primer and RP & WW brass. I can find no info on W748 used in a 45-70, but see some people are using it. Is this a safe load to use in a Sharps rifle, 1895LTD Marlin, or a T/C Contender.
