dskinsler83 Posted June 16, 2012 Share Posted June 16, 2012 I could have sworn I saw where you take a FMJ load and drop it by 10% to start out for Lead load. Is this correct?? Link to comment Share on other sites More sharing options...
Guy Neill Posted June 16, 2012 Share Posted June 16, 2012 That would work. Try to be certain the internal volume is not materially different (smaller) when the new bullet is loaded. Guy. Link to comment Share on other sites More sharing options...
OzzieF Posted June 16, 2012 Share Posted June 16, 2012 That works for faster powders from what I've experienced. The slower the powder though the less the difference in load amount between fmj and lead/moly. Link to comment Share on other sites More sharing options...

The slower the powder though the less the difference in load amount between fmj and lead/moly. That has been my experience as well.m Link to comment Share on other sites More sharing options...
Bshooter Posted June 16, 2012 Share Posted June 16, 2012 Sounds right, I load 4.1gr of VV310 with a 230gr FMJ and 3.7gr with a 230gr Lead RN. Power factor is about the same. Link to comment Share on other sites More sharing options...
warpspeed Posted June 16, 2012 Share Posted June 16, 2012 There is usually no shortage of published load data from the various powder mfgs for lead bullets. What can you not find ? Link to comment Share on other sites More sharing options...

warpspeed Posted June 16, 2012 Share Posted June 16, 2012 I'd probably do what you proposed in the first post. Link to comment Share on other sites More sharing options...
echase1 Posted June 26, 2012 Share Posted June 26, 2012 No harm in the 10% reduction, just make sure that you are careful if you hear or see anything that would let you believe the round did not make it all of the way out of the barrel. Probably a highly unlikely scenario, but big surface areas with much friction could be an issue if the charge is too light. Link to comment Share on other sites More sharing options...
SoonerPast Posted June 27, 2012 Share Posted June 27, 2012 In 45 acp, 4.7 grains of Clay's under a 185 grain lswc, is working for me. Length is 1.245. Link to comment Share on other sites More sharing options...
OzzieF Posted June 27, 2012 Share Posted June 27, 2012 (edited) I used a 180gr Bear Creek Moly @1.135" with 5.3gr of WSF for my .40 load. It made major in my old Glock 35 with LW barrel and made major in my 5" Infinity. With the 185, I'd start at 4.7gr WSF@1.135" and work your way up to 5.3. Maybe increments of .2 4.7 4.9 5.1 5.3 The powder is a little reverse temp sensitive so in summer might be a bit lower than winter. Just adjust for it or shoot a hitter load in winter by about 5pf.
