I love these kinds of experiments! What's your goal here as far as speed, accuracy? What other powders do you have on hand? I really like Unique in big cases. And Blue Dot is surprisingly consistent in rifle cases. IMR 4227 is often the accuracy powder for this kind of stuff in my experiments. Have been playing around with H110 too, but I'm not sure what I think of it yet, and wouldn't recommend it, as it seems to produce high pressure quite quickly in bigger cases. 5744 is also one I've tried and like for consistency. Titegroup is next on my list. My experiments have mostly been with 30-06 and 30-30.
Are you thinking of hunting with this combo? Seems like that TB load would be slick for deer in the thick. Every reduced load I come up with, I always consider whether it would work for the short/medium range deer scenario.
I wish I could get my hands on some SR4759. Keep us updated, and thanks for posting!
