Recently I acquired a new (to me) Win mod. 70 in 270 Win. with the intention of trying it with cast lead bullets and using the original iron sights rather than a scope. I also acquired on older Lyman 119 gr Loverin style mold and more recently, the Lee 135 gr. mold. So far I am very pleased with the results. The Lyman bullets have been giving nice 2.5" groups at 100 yards. The Lee bullets seem to shoot a little better in the first test at 40 yards yesterday. After trying several powders in the last couple months, I settled on 5744 and RE-7 as my primary powders with the 5744 being slightly better. This old rifle's (manufactured in 1972) barrel seems to like velocities around 1900 fps. Every rifle barrel seems to have its own personality with cast lead, of course. I did add a Williams low profile peep sight (WGRS) which fit beautifully into the rear scope mount holes which is great for older eyes like mine. My lube is Lee Alox for simplicity and my own lead alloy is not that hard (60% pure and 40% chilled hard birdshot).
