Mark C. Posted May 30, 2007 Share Posted May 30, 2007 Guy's, I need some help please. I need the OAL for .40 180gr. TCFM Zero bullets. I normally load 180 JHP but a friend wants me to load for him and he brought me over the TCFM's instead of the JHP's. I normally load to 1.115 do I stick with that for the TCFM's? Thanks in advance!

Brazos SC Shooter Posted May 30, 2007 Share Posted May 30, 2007 Have you measured the two bullets to determine if they are the same length? If they are the same length and same weight then it will make no real difference. If the bullets your friend brought you are longer then you could potentially create additional pressure by loading to the same length. 1.115 is a little shorter than most factory. Are you loading ot this length for feeding reliability? Link to comment Share on other sites More sharing options...
Mark C. Posted May 30, 2007 Author Share Posted May 30, 2007 1.115 is what the Lymann book shows for a 180 JHP. The TCFM is shorter then the FMJ. Link to comment Share on other sites More sharing options...
Flexmoney Posted May 30, 2007 Share Posted May 30, 2007 1.115 is one the short side. Which, at 40 Major, increases pressure. Pressure in high enough in the 40 to start with. What gun(s) are you loading for (yours and his) ? Link to comment Share on other sites More sharing options...
Mark C. Posted May 30, 2007 Author Share Posted May 30, 2007 Loading for a Glock 22. Minor not major. Link to comment Share on other sites More sharing options...
Crusher Posted May 30, 2007 Share Posted May 30, 2007 I don't know anyone loading .40 shorter than 1.135 even for minor and most of the Glockers I know load out to 1.140-1.150 even with minor loads and factory barrels. Link to comment Share on other sites More sharing options...
