I am relatively new to the 30-30AI but I really like it. Recently worked up to 41.0 grains of Lever evolution powder under the Speer 150 gr. Flat nose for 2550 fps. The case holds right at 4 grains more than the standard 30-30 and the straight case makes for much less case head thrust and case stretching is almost eliminated after the first shot. I typically work up to no more than three grains higher than standard 30-30 loads but that is just because I am being careful. In my rifle the 150 gr. SST is a real shooter and expands quickly at 30-30AI velocities. My needs could have been easily handled by the stock 30-30 but due to a happy accident the used barrel I bought off this forum had been chambered for the AI version.
I stand for the Republic and all who oppose me be cursed!
