I was reading an article in a new reloading magazine and I ran across an article on converting berdan primed cases to boxer primed. I have a bunch of 8×56R wartime cases that are berdan primed. I pulled the bullets and ran them into my 8X50R die to resize them and can use them once with the berdan primer. The last paragraph of the article states "The MSRP for the Sharp Shooter conversion kit is $39.95; 100 sleeves cost $14.95. Visit 22lrreloader.com for more information." I went on the site and you have to click on the Berdan Reloader tab to see the kit.
