To add to what someguy said in a prior post, unlike the Ruger Judge, the Rossi Brawler doesn't have a 3 inch chamber. It has - as near as I can tell - a SAAMI spec chamber for the .45 Colt. I measured it at roughly 1.6" which is max COAL for the .45 Colt. There is no 'jump' for the bullet as it leaves the brass and before it engages the rifling in the barrel. The three inch .410 shell will be in both the chamber and in the first 1.4 inches of the rifling in the barrel.
Accuracy is very good in the Brawler.
