BirdHunter,
I too have used and like H322 with the Sierra 125gr JHP. For deer, this bullet is really hard to beat in the .30/30.
I had a batch of the original milsurp. H322. I could use 36.5gr in a Marlin 336A w/24"bbl. Velocity was around 2,650fps. Very effective on deer! About like a .257Roberts or .25/06 to ~150yds.
However, later lot's are somewhat faster burning. 34.5gr seems to be max now. Velocity duplicates the published figure of 2,550fps, and from a 20"bbl, not the factory 24"bbl.
My best friend uses this in his WinM94 and has "pole axed" quite a few deer with it. (as he puts it) He uses the M94 where shots will run under 150yds (WinM94 has a reciever sight on it), where shots run over 150yds, he uses the .25/06.
I killed my second largest pig with the 125gr Sierra JHP, complete penetration on a broadsde lung shot at ~70yds on a 175lb pig. Very good blood trail too.
I too shoot a lot of the Lee 160gr FN (mould listed at 150gr). With a gascheck I use either 30.0gr of IMR3031, or 32.0gr of RL15 for around 2,300fps.
My older brother shoots a LOT of these over 7.5gr of Unique, sized to .309 Tumblelubed w/o a gascheck and gets wonderful groups at 50yds, AND, they shoot to his sights too. Go figure !
