Tinkering about replacing the firing pin spring on a Remington 700, but I am not sure which to chose, there are numerous options for replacements.
I got this Win 308 second hand from an elder f-class shooter - through a middle man.
Not sure what is the gun - total age, the barrel for sure is low # shots but I assume it was stored with bolt removed.

Why would I replace?
Because for a cost of $10-15 it is a consumable. Also I have a 30cm white sheiss outside for a next while :)
 
Thanks for advise "If it is 24 pounds or more it does not need replacing".

To go with shorter and stronger or longer and softer - spring?
Just asking for education.
New spring is a new spring, and shall last for a while.

Next month - or two, I cannot go shooting outdoors anyway.
Way too much of time to tinker.
 
Shooting at 300y BR rings I can confirm I have no pronaunced vertical dispersion. Occasional flier at about 2 or 3 clock.

The gun was jumping to left of center before I got myself a front and rear mechanical rest. Still jumps a bit and no clear follow through. I cannot confirm would that be coming from a synthetic stock alone (I made some changes on stock).

A friend was reloading for me before I stopped the shooting season. The average 5 group sizes < 1.8" at 300 with mix all weather conditions. No Labradar data back at that time.

Today I have all my equipment (tools and Labradar) ready and started reloading for myself - from scratch.

So, still winter at my place, looking for things to do a homework. :)

It’s been tough getting anyone to send up Wolff springs for awhile. PTG is still good with sending replacements for Remingtons though. I got a dozen sent up justify the shipping.

Are you including the flyers in your 1.8" groups at 300 yards?
If you are averaging that with no vertical dispersion , I doubt if your firing pin spring is weak or has anything to do with your group size.

Yes, I am always calculating average from the full number of shot groups. With my BR airguns if I shoot a tin per session/day I am averaging the MOA from a entire tin shots.
I was competing in shooting sports over 15 years and learned in diapers that it is not worth to cheat on rounding scores.
I did not measure the spring force yet, I am working on my new digital pressure force meter I am preparing for bullet seating. I will measure these days.
The spring is inexpensive in relative to chase inconsistencies in load development, just for example.
 
Well, you can do what you want to, but personally speaking I think it is a waste of time chasing a problem that doesn't exist .
If it were me, I would be concentrating on shrinking the waterline on your groups - and as a long time fullbore competitor, I would suggest shooting ten shot groups as a minimum.

Why you obsessed over a non problem firing pin spring ? JUST PUT A NEW ONE IN ! and get on with your WAY more important things ! LIKE learning how to reload ammo properly - cleaning your barrel properly - etc etc etc 👍😀 JMO RJ
 
There's a lot of F Class guys weight sorting their primers on lab scales. It makes a heck of lot more sense than weighing powder to the 100th of a grain; granted and does illustrate the lengths enthusiasts will go for consistent ignition. Whether they can prove it made any difference or not is beside the point. Scrimping on the 10 dollar spring that fires your 15 dollar a box primers that light and send 2 dollars worth of powder and lead seems like a poor way to save a buck.
An ignition analogy could be guys who change the spark plugs in their expensive snowmobiles, outboards and such before they have trouble as opposed to those who wait til it ruins their day.

Springs are a wear item... if you can get them, swap them out every season if you shoot (or more accurately, cycle your action) a bunch.

24lbs is just fine... I did have a custom action that was speced for a 28lbs so ask your manf if not using a factory action.

And Yes, firing pin energy IS something that can be adjusted to suit... and have an "impact" on your groups.

If you are only reaching 1/2 to 2/3MOA at 300 in vertical, there is alot left on the table if you care. At that distance, it would be possible to be 2 bullets tall if all is working to typical F class performance.

If your goal is to be competitive at 1000yds, just note that shooters are staying under 1/2 moa at that distance with top shooters around 1/4 to 1/3 moa in vertical. It never gets better the further you shoot.

Good luck.

PS if this is the best you can extract, consider a new barrel or alot more practise in recoil management...ymmv

I agree, there is always a valid point downplaying a hardcore airgunner :)
Btw, YOU guys big shooters, right? How many shots you have in an average - let say per year?
I can do easy 8-10K rings shots with my BR airguns or well over if I am not careful. :cool:
Just teasing, pls no hard feelings :giggle:
