-JQ- Posted June 8, 2009 Share Posted June 8, 2009 Can you use the same load data for either? I understand the difference in the base of the bullet and was wondering if there is much difference when reloading them. Specifically, MG has 124 CMJ's but no HP's or FMJ's right now - and I need bullets. This is my first 9mm build so I'm not sure it will matter either way...

Matt Cheely Posted June 8, 2009 Share Posted June 8, 2009 In practice there shouldn't be a noticeable difference in loading or velocity. The CMJ's will keep the gun cleaner and not smoke as much. Link to comment Share on other sites More sharing options...
MikeFoley Posted June 8, 2009 Share Posted June 8, 2009 I thought that stood for conical metal jacket? Link to comment Share on other sites More sharing options...

Dan Burwell Posted June 8, 2009 Share Posted June 8, 2009 I thought that stood for conical metal jacket? CMJ=Complete metal jacket. the base has no exposed lead. Link to comment Share on other sites More sharing options...
