Is this the high bulk powder used by the cowboy action shooters? I am looking to develop a plinker load for my 9.3X74mm. I am thinking of using some Hornady hollow point bullets for the Makarov. They are 0.365" as compared to 0.366" for the 9.3mm. These are jacketed but cast bullets are a possibility too. I would like to make up a safe, low velocity load for small game and plinking. I would let the grandchildren shoot with supervision and low recoil loads. Any ideas here? TIA Packy

I've had very good luck getting a plinker regulated for my 450-400, so I suggest you give it a try. You might email accurate powders for starting loads. The loads that regulate for me tend to leave a little unburned powder in the barrels, so I've upped loads just a little to eliminate. I was able to get accurate loads with 300 gr JSP as well as cast bullets. Well worth a try. Bob

My 2 cents........ I like the IMR SR-4759 better than the Alliant 5744. Much cleaner and a quick pressure spike to seal off the case/chamber interface preventing soot from going around the outside of the case.

Grandpa Pack,

Are you thinking of IMR Trail Boss?

I have just started using it with cast lead in .375 Holland and Holland. There is no load data for this caliber but I called the

Hodgdon/IMR ballistics lab at 1-913-362-9455

and told the gentleman of my plans. He thought it would be OK and told me a way to figure what should be safe START and MAX charges. The START that I came up with was too low and needed an additional 3.5 grs. to get a good neck seal. The MAX is spot on as best I can tell. I have a "test barrel", so to speak. The great thing about Trail Boss compared to others, I use Red Dot too, is that a double charge of TB will overflow the case by a significant amount. Also the charge of TB comes up high enough to make a visual inspection meaningful.

YeeHa!

I've got plenty more testing to do but will post the results in "cast bullets" eventually.

Maybe Trail Boss is what I was remembering for the bulk. I wasn't going to buy anything without getting some data. Hodgdon's will be my next phone call. Any other ideas? Thanks. Packy

packrattusnongratus: As posted by P. Steve Morgan, I too have had great success with light loads using IMR's SR4759. If you are going to talk to Hodgdon, ask them about it for your caliber.


Thanks, Dad, for taking me into the Great Outdoors.
