Was questioning my 357 Magnum the othe day...
So been fring mostly 357 magnum out of my first and only gun a S&W 686-6 4in. Hand was hurtin' and accuracy was suffering some. Though I had chossen...poorly.
Then I ran like 18 rounds of 38 SPL. And that was like butter. Nice tight groups at 5 and 7 yds.
Definitely want to run more 38 special, just because I can run 357, doesn't mean I have to at the range.
TL;DR shoot what is comfortable but stepping outside of that zone, can improve you.
