My .36 will easily accept a pushed in ball and patch. That is a .350" ball and .020" to .022" patch. The .40 I had did as well, using the .398" ball and same patches, however the larger the bore, the more lead must be moved to seat the ball into the bore, thus the harder it gets. With the .45, I had to smack the starter. Those who remember the video of my shooting the flinter, may remember the light smack needed.
Smacking the starter with the standard load, ie: .022" patch and ball .005" undersized, will require harder and harder "smacks", the larger the bore becomes. I am talking about the same dead soft lead in all.
As for my .69 with it's even tighter combinations, you have to WANT the ball to go in with one smack, or it will refuse. A large knob/handle on the starter is necessary to spread the force of impact,
which reduces possible pain in the hand. My wife and daughter have no trouble with the .45.
There are quite likely a lot of guys cannot stand to have the fun of loading my .69, or perhaps exert the force necessary to achieve success. My hands are large, heavy and I am not adverse or too
shy to use the force necessary. I still stretch 9 5/8" between the ends of my thumb and little finger.
