I ran into a minor issue with two of my revolvers at the range the other day that I wanted opinions on. I rarely run more than 50 rounds through them, but tan more this time. I ran 100 rounds of Winchester White Box 130gr fmj as well as a handful of Critical Defense 110gr through my S&W 60, and 150 American Eagle 40 gr through my Ruger SP101 .22. I ran all the rounds on about 40 minutes and both were getting fairly hot. Both loads were kind of dirty and smoky. After a while the actions on both started getting a little tight feeling, especially cocking into SA. I tend to over lubricate my pistols at times and am wondering if this could be too much oil collecting dirt? Could it be the dirty ammo? After sitting and cleaning both actions are smooth as always. Thoughts?
