Old Man Graybeard Posted November 24, 2019 Share Posted November 24, 2019 Can anyone tell me which discontinued powder it is that works very well in centerfire cast lead bullet loads? I have seen this information before...but of course I didn't write it down and can't remember. Thanks OMG Link to comment Share on other sites More sharing options...
Imis Twohofon,SASS # 46646 Posted November 24, 2019 Share Posted November 24, 2019 I am currently finishing off the last Solo 1000 in the Middle Tenn area. Been discontinued for several years. I have found Clean Shot to work well and is available. Imis Link to comment Share on other sites More sharing options...
Old Man Graybeard Posted November 24, 2019 Author Share Posted November 24, 2019 Thank you . I believe the one I am looking for is either an IMR or Alliant powder. Link to comment Share on other sites More sharing options...

The Original Lumpy Gritz Posted November 24, 2019 Share Posted November 24, 2019 FYI, you can use Unique to load everything in SASS. OLG Link to comment Share on other sites More sharing options...

Garrison Joe, SASS #60708 Posted November 24, 2019 Share Posted November 24, 2019 You are thinking of IMR 4759. In cast bullet loads for medium sized cases (like 30-06) and large (like 45-70) it was the powder of choice for accuracy with cast bullets for over 50 years. I've got a little left that goes into high-accuracy '06 loadings. It's well worth $40 or more a pound to cast bullet shooters. Why this powder was discontinued is beyond comprehension. Although 5744 and a couple of other powders today can come close, 4759 was extremely accurate in so many cartridges and needed little "babying" to make a good load. Good luck, GJ PS - 4759 was called out many times in Ideal Handbook 36 loads, from 1949. Le'see - that's about 70 years, huh? It was reportedly was used in grenade launching cartridges by the US military for many of our recent excursions overseas, but has been edged out by other propellants.

John Boy Posted November 25, 2019 Share Posted November 25, 2019 Quote Have any idea what a Unique load would be for a 6.5 Arisaka? Unique has a too fast burn rate for the 6.5 (32 RQ). Need a slower burn rate powder such as IMR 4350 - burn rate 118 Quote The 6.5x50 is at its best with medium weight (120-140 grain) bullets and medium burning rate powders. H335, H380, H4895, IMR 4064, IMR 4320, IMR 4350, and IMR 4895 are suitable powders. https://www.chuckhawks.com/6-5x50.htm Desert Pete: Recommend you buy a reloading manual to keep the rifle in one piece Link to comment Share on other sites More sharing options...
Jabez Cowboy,SASS # 50129 Posted November 25, 2019 Share Posted November 25, 2019 Reloader 7 and Reloader 10 Work well with cast bullets .... As does Varget , 4895 and 4350 .. For Long range cast bullet loads... Jabez Cowboy Link to comment Share on other sites More sharing options...

Two side matches, actually. Bolt Action Military Match - a side match for Wild Bunch shooters And Bucky O'Neill Long Range Match - one segment of which is for military repeaters made before about 1912. Both are cast bullet matches (predominately). Good luck, GJ Link to comment Share on other sites More sharing options...

Garrison Joe, SASS #60708 Posted November 25, 2019 Share Posted November 25, 2019 Quote Have any idea what a Unique load would be for a 6.5 Arisaka? Pulled out some old Ideal cast bullet handbooks, specifically the Ideal Handbook # 38 from 1951. The latest Lyman Cast Bullet Handbook does not cover this cartridge, so the loads are getting hard to find. What you use depends upon how heavy a bullet you can find. A 0.268" bullet size works best for many of these rifles. Unique only shows up in the book with a 100 grain slug: 10 grains Unique 100 grain cast bullet (like Lyman 266454) about 1600 FPS 17 grains IMR 4198 100 grain bullet (Lyman 266469) about 1700 FPS And for a heavier bullet, 150 grains (Lyman 266469) 22 grains IMR 4198 150 grain bullet about 1700 FPS (no Unique load suggested) The 6.5 Jap rifles used a heavy, long bullet. I'd bet you have better accuracy doing the same with your cast bullet loads. These are just about the same powder charges I use with my 6.5x55 Swedish Mauser with cast bullets of these weights. If you have it, I find Reloder 7 works very well in the 6.5 Swede. With a 150 grain bullet, about 17.5 grains of Reloder 7, or a 162 grain bullet, 18.0 grains Rx7. These generate about 1600 FPS (which is a sweet spot due to the fast twist of Swede barrels). Of course, your rifle will like different cast bullet loads from mine, like they almost always do.

Before starting to use cast bullets, scrub bore EXTENSIVELY and THOROUGHLY until patches come out clean. Get all the gilding metal from jackets out of the bore. Because it will make it hard to realize best possible accuracy with most cast bullet loads. Even if you plan to use poly coated bullets, I would scrub bore. Reserve some brass that can be used just with your cast bullet loads. Resize just enough to get the loaded round to chamber freely. Neck sizing is often enough. Use an expander die that allows you good control, and expand the mouth to point where you can get a bullet started in the mouth just with hand pressure. This minimizes damage to the cast bullet.

Good luck, GJ GJ speaks the truth on 4759! I too used up my last remaining few ounces and have transitioned to 5744 as well in 45-70 cast bullet loads. Whats next.... Alliant stopping BlackMZ production?? Link to comment Share on other sites More sharing options...
