Lately I’ve worked with our 290 grain LFN in a .405 Winchester No. 1. Sized 0.4135”, these were dropped from pure linotype. My first outing was so-so and I suspect it was gas check related. The Lymans I had on-hand were a hair big for the base. I should’ve known better because Mountain cut the mold for Gators. The minute I switched, groups tightened.
My Ruger #1 does 1.5 – 2.0” at 100 yards with Hornady’s 300 gr RN. And that appears to be its accuracy cap. Change the powder, alter the speed, and tinker with seating depths and it never dips lower. Unexpectedly the 290 matched the Hornady, even printing sub-1” once. Here’s the best to date – 4 shots same hole, 1 walked out (sorry the target looks like hell but it was done in very wet conditions):
What I like about this bullet is its consistency. Atop IMR 3031 it returns 1.5” at 1,500, 1,750, and 1,900 fps. The only difference between the three is POI. Sized 0.412” they’re also showing promise in my .41 Magnum. And that’s a good sign. I believe proper cast bullets perform across wide velocity windows (by proper I'm referring to profile, dimensions relative to the gun, and composition throughout). This .41-caliber seems comfortable at 1,260 - 1,900 fps, as does our 585 LFN.
So if you cast a lot of .41 give this mold some consideration. The specs are listed in a previous thread...I think you’ll be pleased with how it shoots.
