thanks for the replies
I think you need that funky green tipped ammo to kill Superman and it seems hard to find. I like the long green rail because a few other new shooters are going to the range with me and it is much easier to see movement while they are shooting and point out bad habits. The magazine release and slide release on opposite sides make it obvious when they are not thinking about what they are doing.
I didn't expect much from the old ammo, particularly the Remington. If it works at all it should be good for training how to clear a bad round while firing. Dad lives in a pretty dry area but we'll have to see how well this older stuff performs. I'll lay my hands on some newer cci as soon as I see it. The current availability makes it hard to be choosy.
be just, love mercy, and walk humbly with God
