Need some insight from the CGN help line...

I am new to semi-auto shotguns, and recently picked up a used Weatherby SA-08 12 gauge. Heard great things about them and was impressed by the ergo's and fit/finish...especially for the price

I took it out today to an ALS charity shoot at the Vancouver Gun Club put on by the VFD. Never had it out before this. This gun has a dual valve system that is easy changed to accommodate light and heavy loads. We were shooting Federal Top Gun 1 1/8oz target loads 7.5 shot and I had the light load gas ring in.

Ran without a single hiccup for about 200 rounds, and around our 5th station began to fail to eject. Field stripped it and cleaned the gas tube (outside) and gas system ring. Still ran pretty well but continued to FTE

Is this due to the loads we were using / the volume we were shooting (5 in my squad were shooting this gun and we collectively put around 400 shells through it within 3 hours) or is this due to a lubricating/cleaning procedure I may have missed or another culprit?

I am very pleased with this gun overall and would like to continue to use it for skeet. When purchased it was used but very very lightly (maube a break in period?)

Anyway thought I'd look to those experienced for suggestions.....positive, constructive advice welcomed

Cheers
 
I don't think this would have anything to do with your problems but??? A more likely problem is a partially plugged gas vent hole in the barrel.

All work will be done at the factory at no charge. Please do not return your Weatherby® SA-08 shotgun to the factory before contacting us for return instructions.
 
I'll check out the gas vent holes and see if any are plugged. I am aware of the safety notice and have already checked the serial number and mine doesn't fall in those affected. Thankfully.

It ran like a dream for the first couple hundred then began failing occasionally. I check what you have suggested, hopefully it is something simple. Thank you

Any more insight appreciated

My 930 does not really like target ammo with aluminum hulls. The aluminum expands and sticks to the wall causing occasional FTE's. This issue also happens with my 590.

I switched to handloads with brass hulls last month and for the last 1000 rounds have had 0 issues, even with 3/4 uber light loads.

Brass hulls are key for my 930 and 590. (another way is to load the initial round with a brass hull and the second with a cheap aluminum hull. I had a flat of Winny I had to get rid of and that's how I did it.)

Now I only run brass through both of them and life is good.

Hope that helps.
 
One of the attendants at the club mentioned it may be the cheap loads with the aluminum hulls as you mentioned and the gun was getting quite hot from all the use between the 5 of us so it may very well be the issue. I also ran my 590A1 just to shoot it and it was fine but it only saw 30 rounds maybe. I will try what you have suggested and stick to brass hulls. Very helpful, thank you

Do the handloads help a lot as well, performance wise, or is it just more economical if you shoot in high volumes?

Regards

I'm guessing if you give it a good cleaning and light coat of oil, you will be fine. Did you give it a good cleaning when you bought it?

My friends Dad has one it has given no issues. He did say it was covered in inhibiting oil. He washed it down good with brake cleaner.
 
I took it apart and inspected it when I purchased it and it seemed very clean. Don't know if I failed to lubricate a vital area or not? (didn't apply any except for the choke I put in) There wasn't any gunk on it or carbon deposits anywhere before firing. It detail strips very easily so I was able to have a good look at it. Should I be lubricating any parts in the receiver and trigger assembly? Metal to metal points of friction?

Cheers
 
That's most likely your problem. U should still clean and lube a new gun before use. Consult your manual for what to lube, but yes, you need to lube inside the receiver and and trigger assembly.
 
I would wash it down with brake claener/gun scrubber and follow the manual for where to lube. I bet your troubles are solved. Always completely clean a new gun.
 
Hey adam, what group were you in and what was your score? i was 2b and shot a 48. I had the same problem all day with a mossberg 930. It too does not like the winchester super loads w/alum bottoms when it got hot. I shot first at every station (i am a member at the club) and was sharing the gun with a few people and never had a FTE. But if it was shot by a few people at a station it would jam up. Lubed well, clean, but having over 300 + shells through it in rapid succession didn't help. Win any good door prizes?
 
I was in squad 5b and I only shot a 36....had a great time. Great event, have gone the last two years. Was really hoping for that Silver Pigeon but who wasn't haha. Shot it at the Beretta station though. Nice gun. Didn't have any luck with the green/white tickets or the 50/50 but I got a tin Winchester sign for the man cave, Beretta shooting glasses and a DS Tactical gift certificate. Did you have any luck Ryan?
 
First I'd check gas holes since federals are dirty dirty shells.
They seems to gum up faster then any other shells. Give the gas tube good poke with a brush. If the problem is the gas holes getting plugged after few hundred shots. I'd go with Winchester or clever mirage shells which burn way cleaner then federals do

And don't lube gas holes. Lube makes burnt plastic to stick very fast.
Light oil on action will do fine
