bullets in the C45S casing with Trail Boss.but, what I seem to be hearing also is that the heavier bullets, from the stand point of physics, are better on paper for reducing recoil, safety, accuracy, less leading, etc.Am I getting that right? There seems to be a lot of guys successfully using the. and up, coated bullet in RNFP for Cowboy Action Shooting. coated bullet in RNFP, but one seems to recommend a 180gr., and even 200gr. In checking with my buillet suppliers, some offer the. It then becomes hard, if not impossible, to tell what the heck really happened
The problem with the video is he added a lot of human error by shooting off hand.

While in the same guns, same case a 200gr (with a typical 45 acp target load) the guns shot well enough (2" groups at 15 yards) but a good deal low for POI/POA.Įxcessive cylinder free bore is not conducive to accuracy in a hand gun. In my USFA guns (45) a 160gr bullet in a C45S case is just barely acceptable to me for SASS accuracy wise. going from 1000fps to 600 fps there is a LOT of leeway on bullet weights and muzzle velocity on how all that will effect POA/POI questions. Heavier bullets generally shoot higher.īut when you are talking everything from a 260gr bullet to a 160gr bullet (45 Colt to C45S). Lighter bullets (given same powder charge) are in the barrel a shorter amount of time, bullet impact is less effected by the gun's recoil. In a hand gun the heavier, slower bullets are in the barrel longer time wise, while the muzzle rises in recoil. The dwell time of the bullet in the barrel, results in where the bullet impacts. Best IMO to use a Uberti size cylinder and stay in the mild 45 ACP loading data, or lower. Although I am not a big believer that 45+P loads are a good thing for a Colt SAA size cylinders. I certainly found that to be true in my own use. and 45 acp data was used to develop the cartridge. My understanding using C45S bought from AJ originally is that the case is actually to 45ACP spec.
