Echo what was said about 7-30 factory ammo. I've never had a problem gettting any. Also, that federal load works so well out of my 12" TC custom shop barrel, it will be hard to improve on when I work up loads for it this year. Kiss of death on whitetail also. As you can see from the posts, it's consistently a favorite load. I think it would be better out to 200 yds. than the 30-30 IMHO.
By the way...CorBon now also makes a factory load for the 7-30.
GB posted his progression of loads developed (in case you ever do handload it).
Took two whitetail last year with the factory ammo. They dropped instantly - both about 65 yds. (in fact I was surprised to see that it appeared to be more effective than my .270)
