Well...each manufacture will load different a little differently with different weight bullets.....You can buy a Stoney point gauge and take a reading...Oppps...Sorry...Hornady bought them..and here's a link to them at Hornady now...https://www.hornady.com/shop/?ps_session=fa70dce4346d05fa2953c839277a3e5a&page=shop%2Fbrowse&category_id=b4ee8759b3aa705bfbfc5b4773fc6c46
 and I believe RCBS makes one as well..it's here..http://www.rcbs.com/default.asp?menu=1&s1=4&s2=3&s3=28

Somewhere I found a place that showed you how to make one of these your self..but basically you take a resized case and make 4 slits in the case neck with a dremal tool..and push a bullet into it..and slide it all the way into your chamber..it pushes in on the rifling but stays in the case when you remove the case...I haven't tried it yet..but plan on doing just that in the next couple of days..

Hope that helps..
