Is a load of 19gr. 2400,WLP,W-W Super, 300gr WFNGC, 1.625" O.A.L. over MAX in an Ruger SBH? I tried some today working up from 18gr and extraction was a little sticky at 19gr, Not real bad just you noticed it took a push on the button to get it to move.

Well, Alliant's max with a 310 gr. lead SWC is 13.5 gr. of 2400. Now they used a Federal 150 primer and you should have more powder space, but you're probably still a mite warm.

I would say you are about a grain and a half over maximum. The max for a Swift 300gr bullet is 17.3, so 17.5 would be as far as I would go with MY Super Blackhawk. Lead usually shoots with lower pressure, if you want more velocity, I recomend you use some H110, or LilGun.

I had a chance to chrono these H2400 loads today. 18.0grs. of the old H2400 went 1170fps and 18.5 grs.  went 1256fps out of the 5-1/2" SBH and did 1470fps and 1548fps in a Win94 Legacy 24". I did not try the 19.0grs. as it was obvious it was too much!!!! Thanks for your input. Have any of you tried AA#9 with the 300WFNGC?

I use 21.0 grains A2400 and standard primer with Cast Perf's 300 grain WFNGC in my SBH. It's very accurate, and shows no signs of excess pressure.
I've tried H110 & W296, but just can't get the accuracy.

Leo,
All of the load data I have, both from the net, and published, shows your load of 21 grs 2400 to be 4 grains over max. You may not think you are getting pressure signs, but you are on dangerous ground. The only firearm chambered for 44 that I would shoot that load in is a Freedom Arms 5 shot. Just felt obligated to point this out.

Just wanted to point out that a 5-shot custom Ruger can handle a much hotter load than a 6-shot factory Ruger so please take this into the consideration when exchaging loading data.

Have fun and be safe!

Leo:

What H110/W296 loads did you use under the CP 300g WFNGC in your SBH? And what diameters were they?
