I really like a few all lead bullets. All my rifles and calibers are White Rifles open sites most with peep.
In my Wilson Barreled .504's I like a 510gr my brother casts shoots well 3 shot groups at 100 yards 1 1/4, I also like No Excuse bullets in the 495gr for the .504 shoots very simular to the 510gr, another great shooter is the White Super Slug 600gr bullet 2" groups at 100 yards.
In my Clerke Barreled .504's I like the 460gr Bullshop bullet shoots 1 1/2 in groups at 100 yards.
My .504 Pistol I like the 440 grain White Super Slug.
My .451 cal Whites I like the 460gr White bullet and a 460gr copper gas checked bullet my brother casts. Both bullets will shoot 1" easy at 100 yards.
My .451 pistol I like a 400-423gr bullet
My .410 cal's like 423 grain and 440 grain bullets cast by Moose, will shoot one hole forever.
My .540's like the Noecuse 540gr and the White 750gr super slug. That one hurts though.
