[QUOTE="Buttermilk, post: 2951529, member: 5262"] Mine was never a 30-30 (it was a 30 Herrett) so I can't give exact gains from that barrel. However using Hornady load data for the Contender 30-30 data I was getting 300+ fps increase. In fact, Hornady's data shows only 1900 fps with 150's. I was getting just under 2400 fps (2385 fps instrumental velocity - puts it right at 2394-2395 fps MV as I set mine up at 18 ft). The 30-30 Improved is hot in the heals of the 309 JDJ ballistically, though the 309 JDJ would have the edge in heavier bullets in terms of speed. [/QUOTE]
