Any one have 458 socom load data using 2400?

Title says it all.

There was some quickload data on 458socomforums.com at one time, but I do not know if it is still there and I have not seen any mention of anyone actually using 2400. Although some are using powders like H110/W296 and Littlegun I think that there is more use of powders like Re7 or my personal favorite 4198.

Thanks, I have a number of different loads using different powders that I have already worked up. I am looking to try something in between HS-7 and H110 and have 2400 in the cabinet.

I have not tested or tried any of these and you should start below these numbers for safety

Thank you. Looks like I will be a little light, I started at 20.0 with a 405 but am only looking for 1100 Fps.

This thread is pretty old, but what I found in testing is that 24-25gr of 2400 with a 300-325 gr cast will cycle correctly in my 16" carbine length gas system. I increased the load by 1.0gr until I would get lock-back with a single round in the magazine. Nice shooting load, too. Crisp report and the cases are clean around the neck, so I am getting sufficient pressure to expand the brass. Some slower powders leave soot on the neck and shoulder. Same load works in my 45/70 as well. I found the 325gr GTbullets work well, as they are gas-checked. Enjoy!
