chbrow10 Posted May 5, 2009 Share Posted May 5, 2009 I usually use berry's 230 grain RN for my 45 ACP single stack bullet, but have found a local source of FMJ (precision)for the same cost. If loaded to the same charge/OAL, will they chrono the same? Link to comment Share on other sites More sharing options...
Jim Watson Posted May 5, 2009 Share Posted May 5, 2009 No. I have chronographed the same loads with two different brands of FMJ that run from 10 to 60 fps difference, depending on the powder used. Link to comment Share on other sites More sharing options...
solaritx Posted May 5, 2009 Share Posted May 5, 2009 I have to agree. Not only will jacket bullets chrono differently, but plated vs jacket will definately chrono differently Link to comment Share on other sites More sharing options...

Kyle O Posted May 6, 2009 Share Posted May 6, 2009 I find that jacketed chrono slower than plated or lead. Link to comment Share on other sites More sharing options...
