Charging force

[filospinato 0]

Hi,

Tried out my newly acquired .410 with some Rio 3" #4 ammo. Factory 4 and 10 mags. Wouldn't cycle at all on either gas setting, I ended up cycling each one by hand. Ejects just fine by hand, shells jam on the feed ramp but that's a different issue. The problem seems to be that either the charging force is too high or the pressure isn't being built up enough to force the bolt backward. This is my only Saiga so I don't really have a reference point as to bolt charging force. Should it be really heavy? I plan on putting a scale on it when I get home to measure the force required, maybe someone here could chime in with theirs so I can compare. No jammed springs, gas port is right into the barrel, no obviously broken bits or other stuff that looked out of place when I took it apart over the weekend.

Thanks in advance.

is it an old or new model? well, you said either setting. so new model. under warranty? got access to some remmy 3"ers? walfart had em for like 8 bucks i think...

 

ya could polish the bolt and carrier like on a s12. and look at the hammer spring etc and see if something is bound....

+1 on trying different ammo, but it may be binding or gas ports not open in barrel possibly.

I'll see if the ammo makes a difference. The gas port is clear into the barrel, I dropped the end of a small allen wrench through the hole to see if it was open.

The gas port is open so that rules one thing out. Is this gun stock or converted? If it's converted I may know what the issue could be from experience.

I've had less than remarkable results with Rio. Misfires, split cases, primers unseated. Seems dirty too. Some Rottweil 2 1/2" slugs were just awful. But you get what you pay for. I've had good results with Rem, Win, Sellier & Bellot, Barnaul Silver Bear (not Golden Bear) and a few others I can't think of right now. Try a few and see what you like.

No, it isn't converted, still the same as delivered. I checked the force required for the bolt to open enough to chamber another round, it's 13½ lbs. Does that seem right? I measured it with a small fishing scale pulling back on the charging handle until it opened enough.

Since it's not converted my tip won't help. Seems about right. Try different ammo. If that doesn't work I'd look in to an exchange from the place you bought it from or warranty from the importer.

So today I made it back to the range with a box of Federal. Awesome! Cycled perfectly, no FTF or FTE with both 4 and 10 round factory mags loaded to the max. The Feds worked on the #1 gas setting just fine. Maybe I righted something or loosened something up when I tore it down after the first attempt but now it seems really great. I'll have to take the Rio ammo back out and give it another chance to redeem itself.

Glad the Federal ran well for you. Hope it helps the Rio run well too!
