I agree. You don't need them to be real short. You just want a clean straight edge on the case mouth for the crimp.If you're going to trim rifle cases every time, trim just a hair under max.
Trimming is the most loathesome part of handloading.
Same here.rcmodel...I seem to have solved the headspace problem by moving the .30-30 shoulder forward .030"...Solved two problems
For bottle neck cases, i trim every time, if needed, BUT to maximum length. I want as much neck length as i can get.
