That's very encouraging, I plan on getting a 10" 30-30, and I'm planning on how to get both performance and accuracy out of the short barrel. As you probably already know, the 30 Herret was created because Steve Herret, Bob Milek, and many other handgun hunting pioneers were very unsatisfied with every attempt they made to get performance and accuracy from the 30-30 in such a short barrel.
I know these guys were pros, and I don't want to seem cocky, but I really think I can do it, and now you tell me you are doing it.
The problem back then was that the usual 30-30 loads spit out all the burning powder right in the middle of the pressure curve, thus destroying both performance and accuracy. When they switched to faster powder, they got decent performance, but still poor accuracy do to the low charge volume causing inconsistent ignition.
But they had some powders back then that still should have worked, like RE-7 and IMR-4198. But now we have powders that are even better for this purpose. Like AA-2015, a benchrest powder that's plenty fast, burns easily, and gives plenty of performance. Better yet there's XMP-5744, a rifle powder so fast that it's almost a pistol powder. This stuff lights consistent no matter how it's laying in the case, even when there's lots of air space in the case. I have done plenty of accuracy and chronograph work with both of these powders in a 14" barreled 308 lone eagle, and they lacked nothing. I don't see how they can fail me in the 10" 30-30 Contender. I'll write about here then.
I'd like to know how much RE-7 you are using with the 150's.
Thanks for the boost
