stevewix Posted January 17, 2012 Share Posted January 17, 2012 Hello all, I've enjoyed the wealth of knowledge on this site for years, and finally have a question I haven't found answered anywhere. Companies like RCBS manufacture and market 'Small Base' die sets for autoloading military rifles to aid in feeding and add a measure of safety. Hornady's 223, 308, and .30-06 dies are small-based to begin with. I've recently discovered the immense value in prepping cases with the Rapid Trim 1200B. I decap in one station, and use the Rapid Trim to size and trim (of course setting up the die with a headspace comparator). My question: Is the Dillon Rapid Trim die 'small-base' enough to use with tight-chamber AR15 and M1A match rifles? I would certainly hate to make a large run of match ammo and find out none of it works. Please help. Steve Quote Link to comment Share on other sites More sharing options...
