I have a model 1858 rem made by Peitta. I tried to put .454 round ball in and could not get them in at all. however the manual says that .454 balls are what is required. Not wanting to force the issue I tried .445 round balls and they worked. When measuring the .454 balls they were between .456 and .460 however the .445 measured .445 to .448. I have shot the .445 balls today and found them to be pretty accurate. So why can't I use the .454 as my manual says is there some sort of manufacture issues or do some take smaller balls any ideas. Is this a trial and error thing???
