| I recently started reloading all of the brass I've saved up over the past few years. Have never reloaded for an AR before. Most of the brass is LC or Win headstamped, and it appears as though the primer pockets are crimped. However, I have a ton of #41 primers that I bought years ago made by Blount Industries. These primers work in my Lee hand priming tool without any problems whatsoever as far as priming the crimped brass. I haven't tried any other brands of primers, but I'm wondering if perhaps primers designed for 5.56/#41 are a little smaller than regular .223 srp? I was surprised that the primer pockets didn't have to be reamed. Any one had this experience? BTW I'm not even sure if this brand of primer can be obtained anymore. Thanks. |

As far as I know..........Boxer primers are made to a "size spec." usually, large or small (rifle or pistol). That way, it's just easier to deal with. Yes, there can be some tiny variation and lot to lot variations. ___________________ But, that being said, I doubt that your CCI #41s were made to a different "size spec." within the brand. ___________________ Side by Side/ Brand against Brand……Comparison of Measurements www.jamescalhoon.com/primers_and_pressure.php ___________________ More Primer Measurements www.radomski.us/njhp/cart_tech.htm ___________________ Anyway......I've "felt differences" while seating different brands of primers with my LEE auto prime (hand tool). You want your primers to be tight in their primer pocket........that's "good enough." You want to go a step further.......perhaps someone will invent/market a reasonably priced strain gauge attachment to a primer seater tool? But, once it's in there.......you got two choices. Continue or not. ME.......I'll accept that my primer was seated with enough force. And, that's "good enough" for me. ____________________ For me........military primer pocket crimps, needs to be "correctly" reamed or swaged. Yes, on some cases, when I've used a reamer, I have cut off more brass (and some less). Sometimes, the amouint of crimp, varies. Though, once done, it doesn't need to be done again. Commercial cases (for the most part) need no special primer pocket treatment. Aloha, Mark |
