I had a problem with my wife's Rem. 1100 LT-20 a few years ago. It always seemed to cycle fine with her, what little she shot it, as long as it was clean and oiled properly. When my oldest grandson, Jackson, wanted to try a 20 ga. "semi" I got the wife's LT-20 out for him. Well, it wouldn't cycle, with any 7/8 oz. load I tried, for him. I could shoot it and it would cycle perfectly. I couldn't understand that because it is a "gas gun", operating solely off of the gas bleed off. I even opened the gas ports one wire drill size, to no avail. He was pretty small,at the time, and about 9 yrs. old. I put it up and he continued shooting the 20 ga. SKB 200E for another year or two. A couple years later (after he had grown a lot) he wanted to try it again. Well, it went too work with the same loads, perfectly, and has never missed a lick.
Moral of this story ....... some gas guns work better when there is some substantial resistance behind the buttstock. You can take the same gun right now and hold it in your hands, off the shoulder, and shoot it and it will not cycle, won't even kick the empty out completely. Snug it to your shoulder and it works flawlessly.
