I'll not comment on this but there's lots to be said in that regard as well as how that info would be treated. In a way, I can understand why they offer little real support. Sometimes, we are our own worst enemies. Especially so when the blind let the blind lead them to their own demise....while buying their product.

They can't make enough to fill the demand, I should say Lapua as I keep hearing about Eley just not putting anything worth trying.
but I am not sure what they need to do. as far as consistency on lot to lot looking at OAL. I am getting great results from lots that I just buy online. FWIW I am not talking killer but usable for me. I went 2-1 for the 3 ARA UL matches I shot last year shooting those said lots.
As Tony said get the ignition right and find the lots and it will work.
FYI, I sent you a PM here to answer your question. as I explained I no longer go on RFC.

Don't blame the ammo manufacturers for not telling shooters and gun builders what to do. To claim responsibility for these offers them little reward. Considering the nature of .22LR ammo, there's little to be gained by ammo makers making claims about where to hit the rim, how hard, and what pin footprint to use. As implied previously, there may be no one answer.

I don’t speak for Tony, I suspect he’ll weigh in but thinking/ testing behind this usually boils down to reliable , measurable, penetration tests on the case where the spring driven systems simply don’t match the measured penetration consistency that momentum systems attain.
Add to that how very few spring driven systems have major wins, it becomes more compelling.

When you realize how many different markets and demographics they serve, I ‘d guess no practical way to do this.
Do you think any of them want to be on the record telling some how to screw with their $9000 G&E rifle?
Try and remember the RFBR market is a small piece of a big pie.
The better RF smiths understand well the needed requirements, there will always be “ blueprinting” from the best.

I used to live down the street from Champion Shooter Supply. Carl used to stock literally hundreds of different kinds of ultra premium 22 lr ammo . Most of that stuff doesn't even exist any more. And prices are insane for the remaining ammo. If Lapua stops making 22lr for any reason ,there isn't going to be much left.
It seems to me the ammo makes more difference than any of that other magical stuff about chambers. I suppose there is some correlation between good barrels and chamber shape and whatnot, but the limited choice of quality ammo probably has more to do with anything.
But that is just one man's opinion.

Anybody know where to get Jim Pepper or Tom Wilkinson firing springs for Turbo actions?
Ya'll need to have some wind flag races and see what's up.
Put out several side by side and see the difference in response time and sensitivity. Pretty cool test. Of course there are other reasons why we like one over another but there's quite a bit of difference between flags and the best can only show what has already happened but is much closer to real time. I think I mentioned this way earlier but it's a good nugget that has to be factored in but, a 10mph wind is roughly 14.6 feet per second.

According to Jim, his springs are all gone.

maybe try wolf springs with the specs see if they have a match

They (Wolff) sells a gunsmith pack with different size springs. one pack in metric and other in what they call English they come in heavy spring and light packs. 20 springs for $10.00 two of each size
I bought some to look for H&R M12 size.

did you find one? I got some springs on ebay I think I picked the wire dia and od of the spring And I got something that would work their not as strong as turbo springs but they work. and they were cheap . Whats the specs on the m-12 spring, I've got lots of springs.

I appreciate the information, but factory springs are still available. I am looking for springs to experiment with the ignition, a little lighter.
since I have added more weight to the firing pin, I want to see how spring rate will also have an effect. if you think about what Tony mentioned about momentum IMO it makes sense since any degradation of the spring rate(strength) can be made up by the momentum of the weight adding to the hit which will give better consistency hit after hit.

This is exactly how I picked my flags. Started with three types of flags and now there's only one type left.Ya'll need to have some wind flag races and see what's up.
I think there's more factors than just that, but that's a biggie. I don't want a flag that shows me what happed a few seconds ago, and some are like that. I want it to be as close to real time as possible and give as much readable info, as possible. Not to mention durability, transport and all the other stuff. Pretty amazing how much stuff we load in the truck to go shoot a gun isn't it? Lol!

That’s why momentum dependent pin around spring,MD PAS ignition is what wins
Please provide a link to the study that shows the higher scores produced by one system over the other.

IMO scores regardless of what system is used is really a reflection of what you see looking at a mirror. that is one fact nobody can dispute.

Come on John. We haven’t had a good (and by good I mean ignorant) SAP vs PAS argument in quite a while. I’m sure some are having withdrawals.
