It really depends on what you want to do. I have a 30-30AI 24" bull barrel and I love it. Fireforming is easy unless you use heavier brass. Advantages over 30-30 include a couple hundred fps faster, longer brass life, and not a run of the mill 30-30. If you load carefully for the 30 Herrett it is a close runner up. Again you can use stronger brass and push the envelope a little. Jim Henry, TC gunsmith, really likes this round and feels it doesn't get enough credit. The only problem is that frequently the throats are oversize and misaligned. (not spouting other people's theories, mine had a .310 throat) Then I would go to AI just for fun. I have formed, and neck turned 375 winchester brass to mine and it should last a long time. Dan
