Thanks for the info. I have .357, .44, and .45 colt revolvers, and I'm already set up to reload those cartridges, so maybe that would be a good way for me to go in a rifle. Then again, there's always lots of used 30-30 rifles around.
Do you have to load from the magazine tube or can you single load a 30-30 with a pointed bullet? (my gut tells me that single loading would be against the spirit of these matches)
Edited to say that I found a few sites with the rules posted, and loading has to be done through the tubular magazine.
Interestingly enough, these sites listing the rules, which seem to be copied from the rule book, mention that the rifle must be .35 caliber or larger. So how does a 30-30 fit in there?
