#9 454 problem

Working up a load for 454 casull, for Ruger super redhawhK 9 1/2"
new Starline brass, Federal small rifle primers, 250 cast bullet, heavy crimp.
I ran a small test with 24.0 grains of # 9, results were good, except for a bit high ES, HI 1460, LO 1241 ,AVG 1376 FPS
That was the last of my #9, so I obtained another pound ( Lot # 0404122054 ). Loaded 50 exactly as before. This batch is showing inconsitant ignition. I have had two squibs, and when I attempted to chrono, some were as low as 1000 FPS.The case show unburned powder that is a brown / gold color, and when I knocked the squib out, there was a large wad of unburned powder.
Any idea what is going on here?

Jim

I've never used #9 powder, but do load for 454. My first idea would be try different powder, or perhaps a Magnum SR primer. I'm not sure if #9 is hard to ignite as I've never tried it.

I do know that all the powders that are good for 45 Colt are good for 454. I have good luck with 2400, Unique, 2400, and (Bullseye in light loads.)

I use No. 9 in some .357 loads with great results using a mag primer.

More crimp would be my first guess.

I crimped the same as all of my other 454 loads. Then after the first squib, I went back and gave them even more, had no effect
I am wondering if I have some bad powder

FYI

Talked to Scott at Accurate. They claim my load is just too light
They recommend a starting load of 28.5 Gr #9
