deerassassin22 Posted December 31, 2011 Author Share Posted December 31, 2011 This is what I figure I would start with 4.8gr N320 1.160 COAL Federal SP Match (Cheaper the Regular Primers) and for a Jacketed CMJ MG 180gr I went 4.8gr N320 1.150 COAL Federal SP Match (Cheaper the Regular Primers) Anyone see any potential EXPLOSIVE problems here? Maybe for my B-day next month get some better books. Link to comment Share on other sites More sharing options...
DoubleA Posted December 31, 2011 Share Posted December 31, 2011 Is BB written on the box or is it initials of the manufacturer? If they are just lubed lead cast bullets you can even go a little less on the powder. I was making major with 180 grn TC lead over 4.5 gr n320 at 1.130 OAL out of my G35.

deerassassin22 Posted December 31, 2011 Author Share Posted December 31, 2011 I found out what BB means been using some google action BB+ Beveled Base. And thanks for that information I will see if I got some more brass around to try that out as well. Link to comment Share on other sites More sharing options...
