Loaded up 350 rounds of 38s using 4 different powders and 4 different bullets. Guns in question are my 66-2 I bought new ~1980, and my dad's NYPD M&P from 1950.
The issue was there were several (many overall) that would not chamber in the M&P but easily chambered - as in dropped right in - in the 66.
Were the older guns made with tighter chambers?
Also interesting was how the older M&P shot some loads MUCH better than the 66, even though velocities (over the chrono) were right about the same..........
Any insights?
