I was thinking the same thing, but then figured that they're the swaged ones I haven't messed with yet. Then again, and for the record, I strongly prefer cast in my .30-30s and most other calibers, this thread is about accuracy, and like has been said here many times, cast is NOT a disadvantage in the .30-30 at all, and if anything can be an advantage. So if someone chooses to do their testing with jacketed, I see it as a limited test that the rest of us should be looking at as a bottom rung that we should all be able to exceed. Not talking trash, but just in my experience, all three of my .30-30s are more accurate with cast than jacketed.
