I have the RCBS and haven't had any issues pulling 44 Magnums or any of the 45 calibers as well as 30 caliber and 28 caliber rifle.
I just cinch it down, no need to torque on it. I wonder if tolerance stacking may be at play here making certain combinations of collets and pullers work more or less easily?
Glad to hear the Hornady puller works good for you guys too.
