I have loads for a couple of cartridges using RL-15 that I want to try RL-15.5 on.
I've been pinged twice on some, probably time to buy a couple pounds...

For a Whelen I loaded some 250 speers over this stuff to figure out pressure, and also some 310 woodleighs. Unfortunately won't be able to shoot it for a few days.
About 58 grains will fit into an unfired norma/nolser case, pretty high up the case neck, but with the powder settled with a high-end vibratory device (electric toothbrush), I couldn't feel any or hear much compression under a 250 Speer at 3.35 COAL.
Probably get a little more into a fired case. Less if you seat deeper. From memory, I think the same cases hold about 60 or 61gr of RL-15 at that COAL without crunching.
I have pretty good data from this same rifle using RL-15 for various 250's. I'll report back.

Last night, as I lay in bed, thinking about this powder; I thought about using it in my 338-06. Then I was to sleep. lol
As time permits, I'll prolly try some in my 338-06.
Happy Saturday!

They had a bunch at a local shop the other day but it was $55/pound so I passed. I spent my change on a blr81 in 358 win instead and as I was leaving thought that 15.5 would probably do well in the 358.

I've developed loads for the .338 WM with 200 grain E-Tips and .375 H&H with 270 grain TSX using RL 15.5. Charge weights are similar to what I have used before with RL 15. I'm getting some additional velocity and good accuracy with RL 15.5 plus it's more temperature stable. I like it!

I'm waiting for 15 3/4 to come out..
I try to stick with the basics, they do so well. Nothing fancy mind you, just plain jane will get it done with style. You want to see an animal drop right now? Shoot him in the ear hole.

I made some home brewed RL 15.5...
small batch.... 50% RL 15 mixed with 50% RL 16..... enough for like 10 rounds...
it went Bang, like any other powder....
I was both surprised and proud of myself...
now I can move on with my life, and still look at the empty shelves at my local Bi Mart...
but the knitting section of the store is still well stocked, and so was the paint section...
life is still wonderful for millennials...with the man buns... lol.......I like it!

I loaded a box of .308 Win with 180 gr ballistic tips and RL15.5 and I like it. FC brass, Fed 210 primers, 45.0 gr of RL15.5. Did not chrono. A couple rifles went .5 MOA for 3 shots. A couple other rifles were in the 1 MOA neighborhood. I also shot 180 gr coated accubonds and they shot well. Only issue is that 45.0 gr is pretty full in a FC case, up to case neck.
