Anschutz 54 firing pin spring

[ATFIV]

My 54 msr is stored de cocked when not in use. Spring hasn't been changed since in 5-6 years.

Is there a preferred spring and how often should I be changing it ?

I replaced my spring once a year or if it starts to shoot low. since my rifle is an early match 54, I have to use Wolff springs since original springs are not available.

Yup, Wolff springs.

 

[TRSR8]

Several have had horrible luck with Wolff in 54’s, including myself. This was a while back.
If at all possible get OEM springs and make sure that includes the small one for cocking indicator

 

[wsmallwood]

Anybody ever put a 5071 ( I think that's the number in an older 54?)

Thank you for mentioning if it's shooting low.

I performed the same sequence before and after lunch yesterday and the averages speeds repeated to the number.

One magazine of Midas + that had been in the fridge
-ammo temp 42 degrees, ambient 50. velocity avg 104

One magazine that was in the warm house and then exposed to lower outside temp
-ammo temp at 62 degrees ambient 50 velocity avg 114

.5fps change per degree of ammo temp is very similar to what i've recorded shooting in the summer.

Is .5fps normal or function of weaker spring that shows up in ignition?

Thank you sir. I'll reach out to Mr. Stepp

I just sold my last spare to Joe Besche. all my Match 54 had them or a 5018 with the correct sear catch. if you have one you might have to grind a relief for the cross pin the holds the sear catch in place.

Tim,

Some of the 54 1700 springs were a couple coils longer; I had the same problem in a batch of springs and suspect it may have been 1700 springs. the correct match 54 were 32 coils and the 1700 were 34-36 coils. my work around was shortening the rear pin guild. so, they didn't bulge out and cause binding in the bolt.

A lighter pin hit from a weaker spring can cause ignition problems and POI changes. during warmer temperatures not so noticeable but in cooler temperatures I see POI go lower and my rifles are not tuned for a low POI I know time for a spring change.

Interesting. Twice I ran a test where I backed off the Anschutz 54.30 bolt spring knob to the point of misfires. The chronograph showed no significant change in extreme spread or standard deviation.

Any change in POI?

I was testing the myth that a weak spring caused the group to open up. In that one rifle it didn't. Perhaps consistent spring pressure is more important than spring strength. But I am curious now. If I find the time I'll test the POI shift.

That is correct consistency and not how hard a hit is the key to a good ignition. too hard a hit can cause more problems than a weak spring.

I agree with Lee. I haven't messed with the spring on my Anschutz BR rifle but I have on my X3L and 2500X. I made a fixture to check strike depth off the back of the bolt. I didn't like all the vibrations the new (stronger) springs were giving me. So I went with lighter (relaxed) springs and, according to my measurements, they're consistent and work fine. I get a misfire in the X3L once in awhile which is where I want it. I recock and the shot goes right where it should. Even so I still usually go to a sighter and shoot it just in case

Is your 54 MSR a wing-safety model?
I had a 54 that was built as a BR rifle by Calfee. It was a wing-safety model from the seventies and I bought a Wolfe FP spring for it. I've since sold that gun and still have the spring somewhere if you want it.
Just drop me a PM and I go down and find it for you.

Two-pack Extra Power Striker Spring Anschutz 54 with .195 firing pin.
@PWNolan do you know if these are for older or current models?

I honestly do not know. From the description (54/1400) series it should be the longer spring for the older rifles. My 54 BR gun has a 1400 series action from '69 and it's a long spring. I have several extras but they're not in the original package. Not even sure if they're Wolff or Anschutz springs

I believe the newer actions use a shorter spring. I have spring set that someone sent me thinking I could use it. It's marked 1800/1900 series and has a short spring. That's assuming the packaging is original. I could also do some digging over on RFC but probably best to just defer to Tim @Tim Slater Lee @Hi-NV Shooter or Glenn @grauhanen One (or all) of them will have more experience with the newer actions than I would

What specific model are you looking for springs for?

 

[houligan]

I've heard that these extra power firing pin springs will cause unwanted vibration or movement of the rifle upon firing. What about McMaster-Carr? Does anyone think they may have a spring that would be a close fit to the original, or a cut to length spring that will work? I'm not sure on the spur of the moment but it seems that Calfee discouraged the use of extra strength FP springs. Lighter springs, less vibration, just so you don't go so light as to cause misfires, but keep uniform ignition.

Those are for the pre 1977 Match 54 with the wing safety. there are two diameters the early 1400 series before 1977 which uses the 0.195 diameter spring and the 0.220 which are exclusive to the so call 1600X actions. 1977-1979
the newer 1980+ use a shorter spring along with a secondary driving spring/cocking indicator spring. on these you should replace them as a set.
