Primer Size Question
Posted: Fri Jul 27, 2012 6:26 am
This may seem like a silly question...but I am hoping T can weigh in on this.
All the load data I am finding for the 450B calls for small rifle primers. And to the best of my knowledge, Small rifle Primers are actually smaller in diameter than Large rifle primers. My question is this....
Since we know that the 450B is Hornady/Bushmaster's version of Tim's 45Professional, and he developed that round from the 284Win brass....and 284Win Brass uses a Large Rifle Primer (according to load data)....When/how did we get from Large Rifle Primer pocket size to Small rifle size?? And why? And an even bigger question is...IF a person does try to use 284Win brass in place of factory 450B brass for loads, with the large rifle primer, what changes in charge weights if any should be used to start working loads up??
I hope I am not the only one that has ever wondered this...and maybe I am way overthinking it...but curious minds just gotta know...
Thanks all
