RCmodel was right about IMR3031 and H4895. I've got but haven't used LVR in the .30/30. I've been feeding a .338MX lately, so haven't tried it in anything else.
However, my favorite .30/30 powder is RL15. I've gotten another 50fps over H4895, and typically get 2,375-2,420fps with a 150gr Rem Corelokt from a 20"bbl.
But, others are right too,when they say that another 200fps dosen't really make a great difference with the .30/30 and appropriate bullets.
Bullet construction DOES make a difference.
Other than the Rem. Corelokts, and Win. Power-Points, I can only recommend the 125gr Sierra H.P. on our "smaller" deer.
H335 isn't that bad of a powder in the .30/30 as it is close to BLC2/Win748 which is what Winchester uses to load the factory .30/30 150gr load with. BTW; the velocity of the factory ammo is 2,275fps from a 20"bbl and the lot# I tested was 35.7gr of Win748 (or non-cannister equivalent.) The 31.0gr load will be just a little under the factory loads at about 2,150fps as another poster speculated.
I didn't like H335 in the .30/30 as it is designed to work best at higher pressures than the .30/30 generates. I got or at least noticed a lot of flash from H335. Recently tried it in a .358win w/180gr bullets and noticed it again. It isn't my favorite .223 powder either as I get better velocities and accuracy from BLC2/Win748. But then again I prefer Reloader15 for this application also.
