Little smaller and no threads. Will not work on my UltraMag Press or the end of new handle on Redding BR-3 Powder Measure. So I sent that ball back to Redding with invoice. The conversion ball handle Redding has for those who like the ball on their UltraMag Press is not exactly the same size as the ball on the UltraMag Press. I'm not giving up on Redding.
Same person answers both e-mail and regular mail.
So e-mail is faster. New handle works great and now looks great. Correct ball arrived and installed, pictured below. The new longer handle with 10 inch of leverage allows for very smooth and uniform operation of the measure. Uniform arm speed is very easy to obtain throughout powder dispensing stroke.
