Wolff Spring Replacement Impact 737?

[mike_srt4]

Hello, I have an Impact 737 and I’m looking to replace my firing pin spring with a Wolff 28lb. When I took the original spring out there is a 1/2-3/4” length difference. The Wolff is longer.

Has anyone had any issues with this?

Jeez 28lb seems way too high?

Typically rem700 actions run a 24# spring. I'd bet lone peak and impact are in the 18-22# range as light the bolt lift feels. What's your reasoning to go to 28#?

One of Erik Cortina’s videos a while back recommended 28lbs for Rem Short actions. I don’t recall if it was a blanket statement or specific to the Borden.

Why not call impact and ask them?

I can I was hoping someone knew the answer to my question right away. I have some pressure tests to complete today and am waiting until the spring is replaced.

I wouldn’t trust the advice of anyone regarding that other than those who engineered and built the action.

With all due respect to EC, I think the best course of action is talking to the manufacturer (Impact).

Maybe this is my problem?
This only has 300rds on it.

Looking back I think that was a recommendation for factory Remington 700

Try it and see. I replace my springs every six months.

Replace spring every year. No need to go 28lbs. Looks like your cocking piece cross pin is dragging in your shroud.
