I second this one
I third this... In the early 90's thats all I could get besides the ready-ject's 18gage 1.5 inch HARPOONS....Yeah I hit those 18 gaugers and when you have to choose those or slin you go with the slin's. I would load them from the back and stick my shoulder then lean on the wall for pressure worked great.

Nice avatar Big Mike if thats you? Bro looks insane.
