Hi All,

I'm pretty sure I'm not just being fussy and this is legit...

Cycling the action of this new Chiappa 1892 is very nice -- except the last ramp of the extractor claw up and over the case rim... It's quite hard to squeeze the lever at this point and the extractor is chewing up the bottom edge of the cases. If I cycle it moderately, the lever stops before the claw ramps over the case rim... it needs an extra 15lb squeeze. Light cycling is not possible. The only way to have a continuous cycle is to rack it hard like I stole it. Is this normal? Is the subsequent rim chewing normal?

I already dulled and polished the sharp edge off the end of the extractor claw because it was chiseling grooves in the backside of the case rims... So I don't see why it wouldn't need another tweak. It should smooth out if I take the edges off the sides of the claw ramp -- but there seems to be a hell of a lot of spring tension in the extractor. Is it ever a thing to modify the spring tension? -- or bend the extractor claw a tiny bit to aim higher? Right now, when a case is held in the bolt, the extractor is "sprung" more than when no case is held... so the claw is longer than the rim depth... See what I mean?

Obviously it's better to have it cycle a bit hard rather than not extract.... Any thoughts?

Here's the chewed brass after ten cycles. Is this normal?



Thanks!

Ok. Fixed it.

Big difference after shortening the length of the extractor claw -- which allowed me to re-shape for a less steep ramp up the case rim. All edges were broken and surfaces polished... It feels excellent and the case rims stay in good shape... They also don't fly ten feet in the air. The extractor now holds the case down against the ejector more lightly before the ejector flings them.

Are you able to post pics of what you did? I have the same gun and it eats brass a bit too.
 
Here you go...

This isn't a how-to -- but more a point of departure. I don't want you to end up with ejection problems if your results aren't the same as mine. Ordering a new extractor from Chiappa could be a pain (unlike in the US)..... I was not all that worried about screwing it up because I can make a new extractor. The trigger group, lever, hammer and bolt have to come out. [EDIT: I just noticed that the extractor pin is accessible without taking anything apart (!).... I was too quick to take it apart. This makes it way easier -- but you'll need a proper block to support the bolt whole driving the pin out. Don't do it unsupported.] The extractor is held in with a simple roll pin and is under no spring tension (or very little). You can gauge the spring tension of the extractor holding the case down against the ejector by simply inserting an empty case under the extractor while it is all held in your hand -- there is no need to insert the pin every time... Clear as mud?

Check with different ammo.

If anybody thinks this is irresponsible, I will delete or modify as necessary. This just worked for me. Check my brass now... and the action is beautiful. The ejection is totally adequate.

This may not be directly related to your original post, sorry for that. My 92 functioned just fine out of the box. No chewing up the cases issue. I wanted to slick it up a little bit. So I bought a "gun slinger spring kit" for it. Wow what a difference that made! It drops the empties right at my feet now. And the action is super smooth. As a bonus, the outfit I ordered the kit from is very close to you. I'm not sure if I can say where on here or not, so if you want, send me a message and I'll let you know where it was. Glad you got your rifle up and running properly. Good shooting, Toni.
 
Rosco... Yours must be a Rossi... Chiappas are made like Winchesters with a flat mainspring... The only coil spring in this thing is for the ejector (and a tiny one for the feed ramp detent). I heard an educated opinion that Rossi springs are much stronger than they should be to overcome any cycling and functioning tightness.... When they're sticked up, they need lighter springs. This gun seems properly engineered spring wise... but like any gun I've owned, it needs a bit of smithing to be as good as it can be.
