Remington rebarrel

[Ram]

I have a 2009 Remington in factory 308 that I'd like to rebarrel to 6mmBR or 6x47 Lapua, but I've been told the factory bolt/firing pin would likely pierce the SR primers. Is this a common problem?

Sounds like an OWT.

If and I say if it pieces primers then there is a simple solution. Send the complete bolt to Gre-Tan rifles and have them bush the face of the bolt and turn the pin down to .062 and no more problems. I had 2 remmys done and now they work great.

I've had two factory 700's in .308 re chambered to small rifle calibers without any problems. One in 6br, the other in 6.5x47.

I have also re-chambered without any problems.

I also have a Remmy that gre-tan bushed and it's works great.

To the original poster....NO, it should not be a problem. Firing pin and spring are the same for all sizes of bolt faces, only varying with action length.

This went in detail on the other forum. You need to distinguish between piercing and blanking primers. Two different things all together. I have never seen a pierce primer, but I have seen several blanked primers.

New to me...what's the difference Butch?

I guess the best way to describe a blanked primer is the cartridge is slammed back against the bolt face after firing. The firing pin then cuts a disc the size of the pin. Normally caused by a weak firing pin spring our excessive head space. It is not caused by excessive firing pin protrusion. If you blank a primer the disc could go through the firing pin hole in the bolt and can cause a misfire. The little disc seems to find a place between the firing pin shoulder and the bolt body that stops the pin.
Maybe Boyd Allen can describe better. I have never personally seen a pierced primer and I have shot many many thousands of rounds.

Butch, and others that have posted on this, lets go back and look at the original question. The simple answer is that the information that he has been given is incorrect. I think that we all have used small rifle primers in Remingtons without a problem for years. The fact that these primes are now in larger case heads should make no difference at all. If his firing pin spring is within spec. (easily checked) the shape of the pin tip is correct (highly likely) and the fit of the pin tip in the bolt face is good. there will not be a problem. Even if the fit is a bit sloppy, in the vast majority of cases the only result will be a harmless crater. I have shot hot loads in .223s and .222s for years that produced craters, and never had a pierced or blanked primer. Lets wait until there is a problem before fixing it. If you actually have a problem that is not the result of simply loading too hot, then sending the bolt to Greg Tannel is the best course of action. He does excellent work, with a fast turnaround, at a price that is more than fair. One last piece of advice, do a proper load workup for your new calibers. Too many come to the internet for loads that may be right for the person that posted them but too hot for another barrel and chamber.
