Clip is stiffer and spring rate higher?

 

Same stiff bolt function whether I use OEM clip or Volquartsen.

 

.001-.0015 can definitely make the difference between slip and press fit, so I'd say that is probably the reason you feel a difference in your bolt resistance.

 

I tried the Volquartsen pieces in my 457 MTR and didn't like their performance. Failures to extract and eject. Removed them and put CZ's back in, but cleaned and polished first. Works great now.

 

My original set from Volquartsen did not work period. No extraction or ejection. I sent them back in January but apparently they are having problems getting them just right. I requested they send the ones I returned and I would try to make them work. The ones I got back are not the original set since these work perfectly BUT bolt operation is very, very firm. Almost like a tight headspace problem
I shot 150 rounds this morning of Lapua and Eley and had not one extraction or ejection problem.
Still working on the stiff bolt issue.

 

After around 40k shot i had a broken extractor so i bought the volquarsten one, what a mistake! Ad to find an original one in order to have a working extraction, cost more than the original one and was suppose to be an upgrade!

 

Recently, I bought a new 457 Scout and decided to upgrade a few components. I have had good success with Volquartsen products so decided why not upgrade the Extractor/Ejector set. The rifle went from operating 100% with the factory extractor/ejector to completely unreliable with the Volquartsen Extractor Ejector Kit. I couldn't reinstall the factory components fast enough.

Epic fail by Volquartsen... they should either do better or pull this product until they get it right!

 

FYI on the volquartsen extractor set: on a recent Pursuit Of Accuracy podcast Josh announced that VQ is offering to replace these with an improved design.

I emailed and received an RMA, we'll see if the replacements work any better...

 

Would you mind sharing the email you sent your request thru? I have a new set also that I bought last year and would like to have a better version if it's available as well. 👍🏻

Thank you sir!
