Quote from the link-
"While working on our CAS loads, multiple times it was suggested we look at IMR 4227, H4227, I and H 4198 and #2400. We did, and found them each vastly inferior to the double base disc pistol powders. “
I would argue this statement .I think he was shooting plainbase commercial cast hard bullets although i didn't read though it carefully yet.He may have had better luck with faster pistol powders then? But don't think those mentioned above are poor for the 30-30!! And his 2400 loads for the 30-06 he shoots big groups with are one of my favorites(10-12g) With one commercial cast bullet of one size i don't think he can make any “firm” statements on cast bullet loading.It only applied to that one bullet.His results were deatiled though.
I hope others here read the link and give input.This is just my take on the little I read.I am sure Ed Harris,Dan Willems,Wally Enga,Pat I etc.. and the more experienced and technical minded guys here could dissect it better.I am a simpleton.
I use a few “recipes” that cover my cast 30-30 loads(and alot of other 30 calibers as well).I use 7.0 of 700X for plainbase bullet of 150-180,10.0 of Unigue for same weight GC bullets,and my favorite load is 12-15g of 2400 with 140-200g GC bullets.I use the 2400 load most of the time.I think about any “Bullseye speed” to “2400 speed" powders work about the same.Burn what you got.
