Hello I have a Turkish built side by side left to me by my father. He always used .410 2 1/2 inch shot shells but usually had problems getting the gun to fire. The left barrel would fire most of the time and the right barrel would fire sometimes. He replaced the firing pin springs twice to no avail. Anyway I took it to the range and also had problems getting the .410 shells to discharge. Usually the left barrel shot, but the right only about 20% of the time. The primer on the right was always struck, but apparently not hard enough. This is when I noticed the following stamp on the left barrel. 36 GA 3 inch The right barrel says ARMSCO Des Plains IL. Under the forearm it says the gun is made by HUGLU in Turkey. I will say it is a VERY appealing shotgun. I believe my father paid $800 for it at a LGS. The wood is gorgeous and the scroll work is detailed and just looks great. Anyway, I was at a local gunshop and they had some shotshells tucked away in the corner of a display. I do not know the brand, I didnt recognize it. They appear to be similar in size to a .410 but they are marked 36 Cal 3 inch. Anyone have info on the HUGLU shotguns imported by ARMSCO of Illinois? All I know now is this is a CZUSA product. Is it possible my barrels are reallly 36 calibre and not .410? The shells are only $9 bucks so it wont hurt too bad to just give it a shot. literally.... will it? Thanks!
