Vitaly Posted June 23, 2002 Share Posted June 23, 2002 I have been looking for data on .40 S&W for 180 gr. Lead bullet (Hardcast). I have only one extensive manual that doesn’t list any (never mind the factory leaflets supplied with different powders). Can anyone enlighten me on this regard? I am looking for data that uses Universal Clays or Titegroup powders. HELP!!! Link to comment Share on other sites More sharing options...
Chriss Grube Posted June 23, 2002 Share Posted June 23, 2002 4.7 grains of titegroup, 1.180 OAL. Should be good for about a 172 PF. Link to comment Share on other sites More sharing options...

ErikW Posted June 24, 2002 Share Posted June 24, 2002 For manuals which don't list lead bullet loads, use the corresponding jacketed load with a reduced powder charge. Link to comment Share on other sites More sharing options...
Lumpy Posted June 24, 2002 Share Posted June 24, 2002 What's the rule of thumb. Lead vs Jacketed. Lead less friction = Less powder? Jackected more friction = More powder? Am I right or wrong? Link to comment Share on other sites More sharing options...
Guest bulm5 Posted June 25, 2002 Share Posted June 25, 2002 Think Lead seals better in your barrel hence the reduced load. Link to comment Share on other sites More sharing options...
warpspeed Posted June 27, 2002 Share Posted June 27, 2002 Vitaly, The Lasercast manual lists both Universal and Titegroup for their 180gr Flat Point bullet start max universal 5.1gr 944 fps 5.5gr 1016 fps 1.190 OAL Titegroup 4.2gr 960 fps 4.6gr 1016 fps 1.190 OAL These were out of an Enterprise Test Gun with a 5" Barsto Barrell, WSP primers Link to comment Share on other sites More sharing options...
gm iprod Posted June 28, 2002 Share Posted June 28, 2002 I think Eric was being careful for your sake concerning the reduced load for lead, as you should always start slightly lower if you are not using the identical set that was tested. Generally lead projectiles will require more powder to generate the same velocity all other components being equal. Winchesters laod data sheet shows this the best AFAIK Remeber more pressure usually = more velocity Lead is heavier so therefore the projectile will be slightly smaller = less friction = less pressure, and will occupy less space in the case = less pressure Lead is softer and is more slippery = less friction. IN THEORY!!!!! Link to comment Share on other sites More sharing options...
Chriss Grube Posted June 28, 2002 Share Posted June 28, 2002 NEGATIVE! Lead bullets take less powder. They seal the bore better than jacketed. Any of the manuals will show at least a .1-.3 difference. That is why a lead bullet at the same PF will generally have less perceived recoil. You need less powder to make the PF.

Jon Merricks Posted June 28, 2002 Share Posted June 28, 2002 I'm with Chris. I drop down .3 when loading TG in 40 Link to comment Share on other sites More sharing options...
BSeevers Posted June 28, 2002 Share Posted June 28, 2002 I agree Lead bullets have greater pressure and take LESS powder than the same jacketed bullet Link to comment Share on other sites More sharing options...
