Years ag made a .36 LR and used a 5/16 dia RR but for the many .45 and up, always used a 3/8 dia RR. Broke a RR and stuck it into my hand so am very cautious asre type of wood and grain direction. .....Fred
They don't have to break to stick into your hand, Fred. I had a 3/8", slightly rounded corners ended rod in my .40. After seating the ball at Hefley rendezvous, instead of using the hole in my
short starter on the rod's end to seat the ball all the way, I just gave the end of the rod a thump with my palm. I instantly knew that was a mistake and said "watch this (I didn't have a beer for someone to hold, honest) When I pulled my hand off the muzzle, the rod came with it, right out of the barrel - it was well stuck into my hand. yeah - it was quite funny - only hurt a bit. I wrapped my hand in a patch material strip, tied off and continued with the trail. IT happens.
