Not liking how Clays meters though my Dillon 550b powder measure (despite using a rubber band to increase the return of the powder slide AND polishing the internal taper of the measure), I have decided to re-try Titegroup (a seemingly better kernel shape) in some very light loads in my K38 (double-action falling plates) using Lee 125 RNFP bullets.
I have noticed that the Lyman Cast Bullet Handbook, 4th Edition, has a starting load of 2.9 grains of Titegroup using a Lee #358-125-FN, for 797 fps, 14,100 psi as listed. This is compared to the Hodgdon data of 3.2 of Titegroup for 856 fps velocity at 8,400 CUP of pressure. Without getting into an argument or discussion about the difference between P.S.I. and C.U.P., I just want to know if ANYONE has used 2.9 of Titegroup with a 125 RNFP Lee bullet in a .38 Special. Or, how data from different sources can be very different.
If you did, how did the 2.9 of Titegroup and the Lee 125 RNFP bullet work out for you in regard to metering through a Dillon meter, squib loads, and accuracy. Please, please stick to the question.
