I unboxed and shot my new Colt Python today. I have the 4.25” barreled version.
After sighting in with MBC coated 158 grain SWC’s, I shot 5 of each hand load I had on hand. They were all developed for my 4.2” GP100. It seemed to like most of them okay. I’ll probably work on some Python specific medium velocity .357 158 grain loads with N340 and some soft .38 special loads over N320 this week. It liked a few of the combos that I have already loaded well enough to not be in any huge hurry. The best group was the last 5-shot group during sight-in (not pictured). That combo was MBC 158 grain coated “match” SWC in .38 special brass over 3.7 N320.
*All shots were taken in single action with my arms resting on my bag at about 13 yards. Here’s some pics of the gun and my targets.
