With the help of several people on this forum I was able to achieve .357 magnum performance with my 2 .38 supers (which was my original goal). I have clocked speer 124gr gold dots @ 1450fps out of my 2 government models without ANY signs of excessive pressure. I use virgin Starline +P brass and mostly Blue Dot powder. I have had NO issues at all with these guns. I did however, change the recoil springs and mainsprings. I understand there might be a legal issue with using handloads for self defense (although there is very little evidence to supprt this statement), so I dont carry these supers, I only use them for night stand duty occasionally. That way nothing could be said if the perp is in my home. Anyway, I just wanted to give Kudos to the super and say I've had fantastic luck with the guns and the loads I worked up. Kevin.
