So I started loading some .45acp today with 230gr lead RN. Never loaded lead for my 1911 before. Well my book calls for 5.1-5.8gr of Unique @ 1.270" OAL so I loaded a dummy to see if it would work and it will not feed in my 1911 properly. So I seated my dummy round deaper to see if that would fix it and got down to 1.230" OAL and it functions fine now. My question is do I need to back off of my powder Load that the book recommends for Unique? Will this increase the pressure to much?
