what sabot do you prefer when shooting .451 or .452 diameter bullets in your Ultra Mag? How easy to load?
The Nosler's are .451 and the Speer's are .452 - both in HPH-12 sabots. They load fairly easy but tight enough that they would never come off the powder. + I am quite confident thay are not leaking. The new MMP stair-step baseeasily expands enough to seal with out stressing the cup + there is a small amount of obturation so everything is tight goin out.
The .458's in an Orange sabot is little tighter but still easy enough to get down.
One thing that helps me is both the Speer Gold Dot 250 grainand the Nosler 260 are a bit longer than the XTP's - I like that length.
