24gn of Belmont Magnum Pistol Powder which is W296 repackaged. This is published max load for 240gn Hdy Jacketed HP. 20in barrel delivering average of 1750fps, Rossi Puma 92. Recoil is moderate (cf 350gn bullet from 454Casull lol).
I find near max or max loads in W296 tend to give best groups across calibres (22 Hornet, 357mag, 44mag). Not my favourite powder for cast however. Prob because most cast I've ever bought is not made for higher velocities. Hope to do better casting my own, eventually.
W296 was allegedly developed for the 44mag and .410bore shotgun.
