I was in Billings MT last week during my travels and stopped in the Scheels store there. Long story short, on the shelf they had both buck and slugs for the 20 gauge, which I have not seen for a very long time.
I have had a little LT20 1100 3" magnum since I was a teen, and it is a very lightweight little thing. Many years back I picked up an extra 2 & 3/4" barrel for it and chopped it to 18 & a 1/2"s. I used to hunt small game with it, and my wife kept it loaded with some heavy loads for a house gun, since it did not have hardly any recoil. It is the type of gun you can literally extend and fire one handed (not very accurately, but still..)
Anyways, I found these 3/4 ounce slugs that show a velocity of 1350 FPS. That is roughly a 328 grain slug, at 1350.
I think that will probably wreck someone's day.
The buckshot was
15 pellet #2 buck.
I figured I may as well go shoot a few of these and put this old lightweight gun back in play. It has such light recoil, and is so short and maneuverable that any of the adult women in the house can handle it with ease, and would not make a bad traveling gun as well.
I know some people are down on using the 20s (mostly because people use the wrong ammo) but a 3/4 ounce slug at 1350 has the similar ballistics to "Ruger Only" loads for .44 Mags and .45 Colts.
I would not feel poorly armed having the little 20 gauge in my hand loaded with 5 slugs.
Not a bad "Old Man" gun
