cnote Posted June 30, 2014 Share Posted June 30, 2014 (edited) From searches i have come to the conclusion 1.165 seems to be the most common OALfor a 124grain jacketed bullet. What is your lowest OAL with this combo. Mag spacers used too.My new blaster seems to prefer a shorter OAL, and would prefer to try that prior to work on the chamber.
