I've tested the LeveRevolution 30-30s out fo my M94AE with a 24" barrel using an Oehler M43. The velocity was 2452 fps (some 40 fps higher than advertised) and the pressure was 37,800 psi(M43). Accuracy for the 7 shots with a 2 1/2X scope was 1.25" at 100 yards. The measured BC was .304 which the old 30-30 a quenuine 300 yard capability. Zeroed at 200 yards mid range is 2.87". The 300 yard drop is 12.26" with 1714 fps and 1043 ftlbs remaining. I did not test it out of my M94 Carbine but out of a 21" TC Contender barrel the velocity was 2335 fps with 5 shots into 1.1" at 100 yards.
The LeveRevolution ammo was designed and is marketed toward the 24" barreled Marlin XLRs. Many want to complain about the lessor velocity in the 20" barreled carbines but even then the velocity is very good considering the 160 gr bullets and much improved BC. That shold improve down range ballistics. Even considering the carbines to be "short range" rifles with decent sights (receiver sights or a scope) the use of the LeveRevolution ammo makes them into decent 250 yard rifles. I have loaded the 160 gr FTX bullets with conventional powders to equal the velcoity of the factory rounds but the pressure is pushing the SAAMI MAP at 42,000+ psi. I'm looking forward to trying the Superperformance powders to be released in January to equal factory velocity with equal pressures.
