WARNING for owners of new 1712 with the 54 bolt

[Evelio Mc Donald]

A lot of new owners of the new 1712 with the 54 bolt and safety in the right hand side, are beginning to have miss fires and also very shallow firing pin indentations which will hurt the accuracy of the gun. This normally start happening after about 500 to 1,000 rounds. I had one shooter at the Texas State Championship where the rifle started miss firing during the second match, the gun had less than 300 rounds thru it at the time, and still had the factory barrel.
At the end of the first day, we replaced the firing pin spring and also the rear short spring, and the gun performed flawlessly thru the remainder of the match.
The original springs were replaced with a set of Wolff SPEED-LOCK STRIKER SPRINGS stock number 61023 with a load rating at cocked position of 23 LBS. about $10.00 for the set. They were almost 3/8" longer than the factory springs.
I hope this info. will help you guys if you start experiencing miss fires, don't blame the ammo.

Huh.
Guess who has a brand new 1712,
Compared to my 54msr the action is a bit tight and a tad more effort to cycle...but hey at 6'4" 240 lbs I can manage...
However a misfire would not be welcome...so Evilio is this a upgrade I can undertake? Or should I send the gun ito you?
As she will be coming your way when you get my new stock....?

Alan, Replacing the bolt springs is job you can do in a few minutes. It is very easy. I sent back a new 1712 for ejection problems, and I have not tested it yet. I also heard that the new 1712s have suspect springs. I guess I will order a few sets. I had problems with 54 MS years ago, and a new set of springs resolved the misfires. I was convinced it was ammo for a while.
Are the spring for a sporter and a match 54 the same?

[Evelio Mc Donald]

Alan, I can replace the springs while its here.
Ter, the springs in the 54 will fit the new 1712 with the 54 bolt. I don't know why, but the existing firing pin spring in the new 1712 is about 1/4" shorter than the 54.

We ran into this at Winnsboro last year with some new 1712's, both factory and new-model rebarrels. According to Jochen, 'there is nothing wrong' with the new 1712/1900 series action... and I believe him. But after seeing a series of ftf's with Eley and Lapua and Wolf and SK and.... well, a guy gets a little skeptical. It isn't just a failure-to-fire problem... you may also see vertical stringing with quality ammo (we did) for no apparent reason. We changed the springs and have had NO further problems.... proabably just a coincidence, tho.

Thanks.

It was not a coincidense, when the firing pin indent is very light, the total ignition is very erratic, which will cause fliers all over, plus also failure to fire every time. The first thought is always to blame the ammo. but believe me, once you replace the springs, everything goes back to normal.

HMMM!
I have a 1743 .222 thats shows a light primer strike. light enough I was suprised it did not ftf. Bought the gun used. thanks for bringing this topic up.

Evelio,Where can you purchase the wolf replacment springs and does the change out require any special tools? also can the 1712 be dry fired or is this something to avoid?

[CWS]

www.gunsprings.com will get you to the Wolff site. You're looking for the heavy-duty springs for the 1800-1900 series bolt and it's a two piece set. No special (or, for that matter, ANY) tools are required. As far as dry-firing goes... Anschutz says it can't hurt the rifle but most folks don't. Fired cases are free (need to come out of your own rifle) and the 'yellow' grade of the plastic wall anchors fit nicely. Turn them after 3 or 4 snaps and discard them when they get too beat up.

[Evelio Mc Donald]

CWS just posted the right info. to get them. If you need help on how to replace them, give me a shout.

I have had four ftf with wolf ammo since I got my new 1712 in a bit over a month ago. Two this last sunday in a match. Got my Wolff springs in today and changed them out. Big difference in the strike, but is there such a thing as too hard or does the pin only go so far no matter how much pressure is behind it. Did you trim any off as the wolff spring was about a 1/4" longer than factory as mentioned? Was quite a bit harder to compress than the factory.

[CWS]

Firing pin protrusion is set by Anschutz and is supposed to stop before it reaches the breech face... (but you can't count on it so don't dryfire without a spent case or snapcap.) The spring is harder to compress because that's what is needed to deliver a sharper blow to the rim. To get it harder to compress, Wolff and JP make it out of heavier wire and make it slightly longer. You have the right part and it should clear up your ftf problems. Should also make your groups more round and less elongated... less tendency to string.
