vipertech Posted January 19, 2009 Share Posted January 19, 2009 (edited) Went to get another batch of primers and all my local suppier had was the magnum small rifle. Is there any performance adavantage to useing these in a standard 223 round. What round are they supposed to be use in? I've only used the standard small rifle in the past. These are questions I've been curious about. Any input. Edited January 19, 2009 by vipertech Link to comment Share on other sites More sharing options...

FromTheWoods Posted February 11, 2009 Share Posted February 11, 2009 Some of the manuals list the magnum primer for certain powders. We use the combo in a few of our older Winchesters. Link to comment Share on other sites More sharing options...
