What's the recipe for the 25-5? What maximum loads do you shoot? And how does it work to shoot the gun point of aim? IIRC there were some issues with oversized chamber mouths and the hight of the front sight so the guns sometimes shoot a little bit high.
Sorry for the late reply. Cataract surgery has kept me busy for a while..
My 25-5 has oversized chambers but it shoots very well with 8.0grs of Unique with a 250gr SWC sized at .454. It is sighted in at 18yds because I use it for bowling pin occasionally and thatβs the distance at our club. Sights adjust to that distance with that load. I have shot 9.0gr of Unique but 8grs seems to be more accurate.
Do not know about all the worry about oversized chambers as Colt SSAβs have them too. I would not shoot bullseye with it but it is minute of bowling pin. π
My Ruger is very accurate with the same load but to be honest I shoot it with the .45acp cylinder in it mostly. It is a one fat hole at 18yds with 6.0grs of Unique and a 200 gr SWC.
