Question for the 6.5 by 47 lapua guys

[scuba52]

I am getting a new shillen barrel I stalled right now on what was a 308. What are the odds of having an issue with piercing primers, and does anyone make a savage bolt head pretty fit for small firing pin.

Savage actually makes two different size firing pins, small and magnum. If your action used to be a 308, you probably already have the small firing pin hole.
I have a 6.5x47L built on a custom action, no primer issues at all. I also have a 6x47L on a 700, and I had cratering from the beginning, but only one pierce primer in about 300 rounds so far. I went with a heavier firing pin spring and the cratering disappeared. Cheaper than bushing the pin hole, but does make the bolt lift heavier. I will probably end up bushing anyway.
In your case, both methods will work if you need them. Bushing the hole is even easier for you since the bolt head is removeable.

TL;DR Use CCI primers and see what happens.

I have two 6.5x47 right now, one built on a rem 700 and one on a ruger precision rifle I've never had a problem with primers yet. Also had one build on a tikka t3 action and no issues there either.

 

[scuba52]

Good. Going to try the cci 450 and see what happens

 

[Alpheus]

Not necessary to go with SR magnum primers either. I use BR4's exclusively and have never had any ignition issues, even in -20 temps.

The consensus world wide is that the CCI 450 is the best primer to use in the 6.5 x 47, however, try whatever to achieve the best accuracy in your rifle by all means.

I found 205m's work best with varget and br4's work well with h4350

I'm running cci 450's in my 6.5x47L.
Stiller TAC-30 gives me just a tiny little bit of cratering around the firing pin,
but not enough to cause any issues

Piercing a primer is weird terminology...

The vast majority of primers that leak are not pierced by the firing pin - the indentation blows out and leaks. It's a rare day that a firing pin is sharp enough to pierce a primer... and then it would do it every shot.

No doubt some primers are tougher than others. In the past the Remington 7 & 1/2 was the toughest and very popular for the hottest loads.

The closer the fit of the firing pin hole and the firing pin tip the better... and the smaller both are the better.
