From a Winchester Western manufacturers catalog I happened to get from a gentleman named Ad Topperwein before he died in 1962 (jeez I'm old), it lists the 32-40 shooting a 165gr lead bullet at 1440'ps at the muzzle. I used that criteria in looking thru some of my old reloading manuals, I have them back into the 20's. Here's what I found that translates into modern components for the 30-30.
Using a 154 Lyman cast #308241 bullet
10.0grs SR4759 =1300'ps
9.0grs Unique =1300'ps, 11.0grs Unique max= 1690'ps
Using the Lyman 311440 150gr cast bullet with a gas check
9.5 grs Green Dot max =1479'ps
9.0 grs Herco max =1386'ps
Using the Lyman 173grs 311291 with a gas check
10.6grs Unique=1568'ps max
9.0 grs Green Dot =1348ps max
11.5 grs Herco =1538'ps max
If you like a low recoiling round out of a 94, try 35.0grs H335 under a 110gr Carbine bullet. Every 94 I've ever shot them out of loves the load but be aware, it has a HUGE muzzle flash and it sounds like a cannon. It really turns a 30-30 into a fabulous carry varmint rifle. Velocity is about 2250'ps and the kids love to shoot these loads.
