Oops! I think I made a mistake (Remington 597)

[tommyguitar]

Well, of course my first mistake was buying that gun.

But, there is a dimple on the side of the barrel in the chamber (from dry firing I presume). It was my first gun and I didn't know any better
The gun cycles perfectly fine now that I have a VQ extractor. It really sucked before though.

Is there any way this dimple could be affecting my accuracy?

Thanks
Tom

I think I will change my extractor but mine shoots fine unless I try to unload a 30rd clip as fast as I can, then there are some jams. But I can't determine if that is gun, ammo, clip or a combo of all three.

I can unload my 30 rnd magazine(which incidently holds 32 rnds) in about 8 seconds!!! No jams. Nice rifle shoots great! (I've got the orange camo one because I liked the fact that it looked different).

Can you post a pic?
Most modern rimfire .22's incorporate a firing pin stop/block to keep the pin from contacting the barrel when dry firing.

The firing pin is retained in the bolt by a cross pin that should stop the firing pin from moving too far forward and striking the breach face, in addition the round nosed pin (on my 597) does not strike the rims edge of the case but slightly in from the edge and these two features should/may prevent chamber damage from dry firing.

I suspect that Remington has reworked some of features of the 597 to try and resolve ftf issues. I haven't heard much #####ing about poor operation in the VTR so I'm guessing they have been changing things over time. The shoulder of the groove in the pin may have been moved back a bit to allow for a longer stroke and cleaner hit on the rim. I have made a new pin for mine with a blade edge and longer stroke, my FTF issued have been resolved but the pin will strike the chamber if dry fired now... It wouldn't take much "Friday afternoon special" at the factory to screw up the machining and cut the groove too far back...

Accuracy change? perhaps it the round is getting mashed up while feeding it might do something... I purchased my 597 after trying someones gun that was a tack driver. I loved the feel of it and it ran perfectly... Mine, not so much. I have had to tinker a fair bit to get smooth operation but accuracy has never improved much over plinking grade regardless of what I have tried.

I gather you can get a chamber ironing tool that will try and press the displaced metal back and repair the chamber. I have a Ruger MKII with a badly penned chamber that once firing issues were resolved (new pin, heavier hammer, more hammer spring pre-load) shoots beautiful little groups. Try chambering and ejecting a round and see it there is any indication of damage from feeding... Try manually placing a round in the chamber and shooting groups single shot. If accuracy improves you may have an answer...

I have found that the 30rnd mags drag a bit on the bolt and cause FTF's due to the bolt sitting a hair out of battery (indicated by light strikes on the rim). I have also found that I get bolt over base jambs toward the last few rounds in the magazine... I suspect the magazine needs cleaning and lubrication to keep forcing the rounds up fully into place in the feed lips.

Do you have any clues as to how the gun jambs (ie, double feeds, FTE, bolt over base...)?

The extremely simple design and low cost manufacturing of the 597 likely results in "variances" from gun to gun... Each my malfunction differently. I have worked through a number of issues with mine and have managed to resolve enough that I'm happy with how it runs... Post info and perhaps we can sort it out...

(1) Each 597 is special in its own way....

(2) If there's any tinkerer up to the task of remedying a 597, it'd be MiltonBradly....

(3) I love Remington bolt-action and pump-action .22's.........but for semi-auto rimfires, I think that the Speedmaster sort of capped-off the run of quality....

Same here. I own two (597 and 597 VTR) both with thousands of rounds through it with no complaints.
