I really like the 30-30 AI. The one I had was a 14" 30 Herrett re-chambered to 30-30 AI. Very Accurate. Consistant sub MOA with Nosler 150 BT's and Hodgdon Varget.
However, I wouldn't personally do a 30-30 AI on a 10" barrel. If it's still a 30 Herrett, I'd keep it as a 30 Herrett. But that's ME.
On a 14" bbl, I think it's an excellent choice, and hot on the heals of the 309 JDJ.
