Okay, I'll be the wet rag on this topic. In 30-30 and 35 remington I find current 5744 gives me excellent accuracy when I'm near the top of the load data. It is one of my 3 go to powders, including 4759 and 2400. On 45-70 the Lyman 4th author swears by 5744, but I have not had any luck in that caliber. 4759 turned out to be the best for 300 grain plain base in 45-70. I started using 5744 because I was low on 4759, then a local gun store had two 4759, so I bought them. Then a few wks later they had two more, I bought them also, long story short every other wk I go get two and he hasn't run out yet. I'm up to 20 lbs or so now and I'm afraid to ask how many more he has. Don't want to draw any attention, It's easier on my bank account.
