I read where Remington has a few boxes of 38 spcl out there with .357 mags in the box, that could be interesting.
I used to buy 44 mag reloads from the same dealer for years then one day there was a miss on my target and then I could not eject that case. Removed the cylinder and pounded it out with a dowel and a rubber hammer only to discover it was a 41 magnum stuck in a box of 44 magnums. I don't buy reloads from anybody anymore and when I open a new box from a manufacturer I pull it out and make a fast inspection of all the head stamps.
I'm to old and to used to having all my fingers and eyeballs to be taking a chance of losing one of them now.
Good intentions will always be pleaded for any assumption of power. The Constitution was made to guard the people against the dangers of good intentions. There are men in all ages who mean to govern will, but they mean to govern. They promise to be good masters, but they mean to be masters.
