Awesome find. I found SR-4759 two different sporting goods store and grabbed both, but after doing more load development in the calibers I run cast bullets I've found I like IMR-4198 just a little bit more. Gary, I'd trade SR-4759 for more imr-4198.
I am using IMR 4198 in my cast bullet rifle loads, and jacketed loads in our .223’s. I’m sitting on about 14 pounds, which should last a while!
I’m good on most powders except RL 7.....which I need to feed my 45-70 ! memtb
