NEVER, NEVER, EVER DO THIS.
4000-MR falls between R19 and H4831 in burn rate. Since there is no data for the 240 mag and I wanted to try some 85grn TSX in it,,, I looked at many different books and started a few grains below both listed charges. 46 grains gave no pressure signs and worked my way up VERY slow. Never DO THIS and somewhat know what im doing after 26 years of hand loading.
After hitting 50 grains, things started to sound right and didn't have a certain looking primer. I slowly worked up higher and the chrony told me a lot also. 46 was only about 3000 fps and ran out of chrony light for true readings. I hit the NODE of somewhat accuracy at 50 grains and got the FPS up to 3200. (but don't trust low light) Since pressure signs was not present, I went further and pretty much maxed it out at 54 grains and FPS is unknown yet. I really think after some major playing with .2 grains of this powder and ogive jump,, I can make it crazy accurate and get the 3450 FPS that im looking for.
This is a spherical powder but damn sure doesn't look like H335 or others that ive used over the years. Im getting a good 90 percent fill ratio if not more at 54 grains and kinda like the stuff so far. I truly hope it will work out for me and some may ask why I want to use the 85 TSX, instead of the 105 Berger that ive been using. One simple reason,,,, the Barnes triple shock is stupid good at all ranges and pass thru bone, meat and anything in their way.
I used all once fired brass for this test and checked all for head swelling or belts being pushed back. All cases is fine and was FLS. Neck sizing should tighten up the groups some but im happy,,, with my idiotic, homemade recipe.
I bought R23 , R26 and R33 today also. Im liking this new TEMP Tolerant Alliant powder a lot,, but data sucks highly. And AGAIN,,, DO NOT TRY THIS.
