Hi All, I'm struggling tracking down some load data for the following combo for my 444: 210 grain bullets with SR4759 powder. (I have both of these items sitting on my shelf, and want to make some lightweight plinking loads.)

The best info I've found so far is a 240gr with anywhere from 25-33gr SR4759, but I don't know if I can use that same powder weight with the lighter 210 grain bullet.

If anyone has any info tucked away on their shelf, I'd certainly appreciate a comment.

I burn a lot of SR 4759 in many calibres, but not in the 444. SR 4759 has a burn rate similar to IMR 4227, so if you find data for that powder, just use the starting load for that until you get to where you want to be.

The Lyman Cast Bullet Handbook (4th edition) lists a starting load with SR 4759 with a 210 grain cast bullet at: 26 grains for 1546fps.

I would be very careful about using the burn rate chart to sub powders.
Those two powders don't show similar data in other calibers.

That is not to say anything about either powder.
I wish I had some SR 4759. That's a"Gotta know a guy that knows a guy" powder.

i loaded up some 300gr fn gc with 24.0gr of 2400 and a tuft of dacron that goes 1624fps in my tc encore with a 23" MGM barrel. its great on deer.

i have loaded the 300gr fn gc with 16.0gr - 25.5gr of 2400 with and without dacron(i chose to load with dacron because my groups were smaller). i stopped at 25.5gr of 2400 because the group size was opening up, not because of sticky extraction. when i used 16.0-22.0gr of 2400, i still have powder residue on the outsides of cartridge. 22.5 - 25.5gr of 2400 there was none. there was also no cratering or flattering of the primers. the brass was ok too. the cup/psi, i don't know.

i would try 16.0gr of 2400 on cartridges weighing 265gr up to 350gr. just go slow working up your loads.

Awesome! Thanks very much sir, that's what I needed. At least it's a start, and I can tweak from there. (Gives me an excuse to shoot the 444 a bunch more. I'm tired of shooting bear loads with a 310gr hard cast...)

Did you by chance maybe mis-post? (Not being a jerk, just wondering what happened here :)) I was looking for data on SR4759 with 210gr loads...

I just got lucky by accident. I bought the SR4759 for slug loads for a 12ga I was messing with. Made a few of those, then the powder just sat on my shelf for the last however-many-years.

Figured I'd maybe try burning some of up in the 444 if there was a way to make it work.
