So I played hooky this afternoon and stopped at Gander to look around. I'm looking at ammo and a guy says to me can I put a .30 Remington "bullet" in my .30-30 Winchester? I said what did you say, and he repeated the question exactly the same way. So I said no sir only a .30-30 will go into a .30-30 Winchester. So I looked at his shopping cart and he had all sorts of .30 cal cartridges including .300 AAC in his cart for his ".30-30" Then he asks me if a .270 WSM is the same as a .270 Winchester! At first i thought he was kidding with me but it turns out he was serious. I told him .270 WSM is a Winchester Short Magnum and not the same as a .270 Winchester and he looks at me like he does not believe me. And he asks why cant I use a .270 WSM in a .270 Winchester? So, to prove the point I grabbed a box of each and showed him the difference. He had the old "Doe in the headlights" look on his face. He said he had not shot the lever action gun in a long time. I said to myself: THank God for that! I could not believe it. I think I might have saved this guy's butt today. Just amazing that there are people walking around handling guns like this today. I'm still sitting here amazement.
