Interesting side note, the third round wouldn't fire. The recoil had pulled the shotshell far enough out of the case that it was hanging up on the side of the forcing cone.
I was able to push it down into the case again and fire it, but who wants to have to open the cylinder, pull that round, etc. etc. Not good.
Now, I was wondering if the tiny, short, abbreviation of a barrel on the non-View had much to do with the results, so having anticipated that I brought along my 4" model 66. Honestly, I don't see a hill of rattles worth of difference.
Here's the result of three shots with the model 66. I shot three to see if there'd be any shotshell pulling, like there was with the non-View. The problem did not recur with the model 66. I do notice that there's almost a gap in the very exact center of the pattern with the 4". The tiny non-View barrel put more close to the exact center. For a small rattlesnake, that could matter; if it's a real, reproducible effect. Which of course I don't have nearly enough data to conclude.
Interestingly, some of the plastic shotshell cases got stuck in the cardboard.
So the model 66 doesn't give tighter groups, but at least it functions for the third round. And you have seven instead of five. But I'm sure not putting a model 66 in my pocket.
Looking at all these, I think about the first rattlesnake I ever saw wild in New Mexico. He was four feet long or so. Would I shoot him with a .38 shotshell? No sir, I would not. So what to do? Go with .22, and aim for the head? I bet that's what Native Texan would suggest. Or do I go full gonzo, and get a Judge? I'm sure not pocket carrying that either. Maybe a snub .44 Special is the answer. Decisions, decisions.
