I got my 30-06 AI up and running about 15 months back. The barrel of my 1982 Rem 700 in 30-06 was shot out, the accuracy and velocity were becoming dismal. I took off the old, turned down barrel, and sent it to Dan Lilja to have a 26" ss barrel turned down to the identical external dimensions. I saw this as a cheap man's 300 magnum since the only thing new I had to do was obtain reloading dies which consited of a Redding shoulder die, Lee 30-06 neck collet die and a Forster floating chamber for my Ultra Seater die which I already had in 30-06.
I've only run about 1/2 dozen different ladder loads through it, using 180 BT/AB or 200 PT/AB. Fortunately the 180 BT/AB bullets work w/ the same load of 68.5 of Rel 25 for 2997 fps and the 200 PT works w/ 68.4 gr of H1000 giving 2853 fps. Accuracy runs .5 to .75 MOA for the first and just sub MOA for the latter.
I'd say in the 15 months I've been shooting it, I've put at least 700 rounds through it. If I'm not careful, I'll shoot it out and have to get another barrel; same caliber too!
