I am unable to locate any BE-86 or Bluedot so I am wondering if my leftover schuetzen and bigbore lead bullet ctg powder will work in the 10mm. I have lots of

H-110, Win 296, IMR 4759, H-4227, H-108 (said to be early AA#9)

They all fall a little bit slower than Longshot on the speed chart. Has anyone seen any loading data for the above or have some experience with it and 180g jacketed bullets?

thanks in advance,

Winchester had data for the 296 powder, while it wasn't very fast velocities as shown, I think there is room for using more powder if you look at the pressure values although you'll be starting to compress the loads some.  Also H-110 can be substituted directly for the same data.  With 296 magnum primers should be used.  Also bullets need to have a very secure case tension fit.  Using a small amount of bullet sealant would help for better ignition properties before the bullet starts it movement.

No experience with any of those powders, but I do have experience with surplus, non-canister powders.  Of those options I would try the H-108.  Reduce #9 data, probably by 15% for a good margin, and test over a chronograph.  Work up slowly to see how close your lot is to #9.  With a little luck it will be a bit faster rather than slower.  That would make it more useful for 10mm.

I would like if someone would take a good closeup pic of the H-108 powder and message me some pics of this H-108 powder.

I can't attach my small 61K jpg pic. I choose the file but when I post it says "could not find path" . Message me an email address and I will send it.

Here is the sample of my first canister of Accurate Arms #9 early 1990 and it is 100% microbeeds

Shot a couple of H108 loads with 180 jacketed out of CMMG carbine with good accuracy and function.
10g 982'/s, 11g 1070'/s

I have a pound of Accurate#7 I will try next.
