Thanks fellas. Cheers Jimthom, yep I bought Cleaver out of them. Well it was only half a dozen boxes, should keep me going a while.
As to performance, manufacturers may do low speed( for revolvers like 38 and 44 special), and high speed options. Eg Speer does gold dots in standard thickness and then what they call their 'SB-short barrel' bullets with lighter jackets for 38 special and 44 special revolver speeds( 800-1000fps).
The short barrel stuff is good for low power or subsonics as you get full expansion at low speed. Pushed faster, about 1200-1300fps impact they start to disintegrate like bombs.
Full power at normal hunting ranges, better options are the standard gold dots, deep curl, XTP's etc. I have never tried seirras.
at very low speeds( something low velocity guys like myself worry about) you need to test a bullet to see what it does, EG the .357 158XTP opens at lower speeds than a 125XTP, and also penetrates deeper at high speed. Its both a better low and high velocity bullet. I havent used 44 much, but from tests see the 180 and 200xtp also have that wide velocity envelope, aka subsonic as well. whereas the 240 and 300xtp are tougher bullets and need more speed.
Good resource in 357 and 38 bullet performance is luckgunner. The guy tests every brand he can at both speed levels on gel and puts them in a table. (scroll down about half way)
