View Full Version : Remy 1187 jamomatic
April 20, 2005, 07:48 PM
I purchased an 1187 premier 12ga from wal-mart about a month ago and it is a jamomatic. It jammed a few times when I shot it for the first time and just yesterday it jammed a lot. By a lot a mean about every 3rd shot. I am kind of new to the semi-autos and I have been shooting very cheap stuff in my gun because I am just shooting skeet. I have been shooting estate and federal's cheap stuff. Is this normal for the cheap stuff to jam like this in a semi or is there definatley something wrong with the gun. I did fire some 3" turkey loads without failure, but in my opinion a 700.00 dollar gun should eat up everything for the most part. Anyone?

There are a few possibilities.
How heavy are the loads? Autos- espically new ones- dont function well with light loads of birdshot. Run a box of whimpy skeet loads, and then try some manly 00 Buck and see if you get the jamming. It could just well be the cartridges.
Also, the gun may be gunked up. Did you completly clean it before you fired it? there may still be factory grease inside it. Clean it right down, wipe everything and try the same loads.
Unlikely, but some wad may be caught in the gas ports. use a bronze brish on the bore, and see if that helps. With a newer gun, there may be a tiny piece of metal where the hole was drilled in the bore. This can catch wad material and block. Pretty rare, and unlikely with a remington.

I have an older 11-87 that has run tens of thousands of shells through it, 95% of them were light 1oz loads. I have had a few hangups after not cleaning for a thousand or two rounds, but other than that it has run great.
I am more inclined to think that there is gunk in the gas system like Death from Afar mentioned. If there is take a solvent and clean all oil and tacky residue out of the system. Also clean the bolt and receiver area and lightly oil. Make sure the gas rings go in as directed on the gas tube also. IIRC it should be the large flat ring first with the inverted cone up then the wedge shaped ring nesting in it and then the O-ring.

I remember shooting trap with someone who just bought a new 1187 from a nice gunshop. Well, almost shoot trap. The gun wouldn't cycle because it had the wrong piston(?) sliding part installed onto the gas tube, it was from an 1100! Like they say, anything is possible!
