Need to change primers.

[46and2]

I have a FANTASTIC load for a 270wsm. Using Remington 9 1/2M primers. I have had two pierced primers in 40 rounds, I thought the first one was a fluke. I don't have a lot of experience with Remington primers, in fact I have always used 210M primers for all my Wsm cartridges.

Are Remington primers really soft? I have never had a pierced primer in this action.
I have never had a pierced primer using 210s even in hotter loads than this.

What are the chances of reproducing a load like this? Shot at 200 yards from a hunting bag.



Does anyone know which primer might replicate the specific brisance?
I not even sure if this old list was ever accurate anyway.

Any help is appreciated.

I struggle to imagine an even hotter load than this. I would not have fired any more than the first couple and pulled the rest.

 

[Doom]

Just my opinion but I think this load is way too hot. You have primers flattening and cratering. The case with the pierced primer definitely looks to have serious ejector swipe. If you want a harder primer then I would use a #34

 

[46and2]

Primers are not flat

I would say, with that primer you are getting a slightly higher pressure than what you had with the 210's and from what it looks like you need to have your bolt face bushed and stop the cratering of the primer strike.

Yes this factory Savage firing pin hole is sloppy. I wonder if PTG bolt face would be of tighter tolerance?

Just an observation. The Fed210 is Large Rifle. The Fed 210M is Large Rifel Match.
However on the Remington the 9 1/2 is Large rifle and then 9 1/2M is Large Rifel MAGNUM, not match.

Yes sir that is correct.

I just checked my inventory, I have PTG magnum bolt faces but... savage must have changed their bolt assembly over the years. They'll fit my older models but not this model.

The firing pin hole is smaller on the PTG


The bolt I'm dealing with has a much different firing pin spring. While de-cocking the different bolt styles I noticed a much lighter spring tention. Maybe it time for a new spring???? Wouldn't light firing pin spring cause pierced primers?

Just have @Grimstod bush your factory bolt and it will fix your issue. No wondering.

We run a 140 Accubond at just under 3000 fps, it shoots outside a dime 200 yards off a bi pod.
Fed mag primers
H4831 sc xxxgr
Hornday brass iirc
No primer issues, but not quite as fast either, no complaints from the deer. So far..anyway

Yeah, deer dont like 270wsm much, lol.
No worries, this chamber is throated long for the longer bullets. And I'm HBN plating bullets.

 

[Sandstorm]

Time for a new spring Sir...

Time for a new spring Sir...

Yes sir, the more I'm reading the more signs point to blanking from weak spring. I was calling it piercing.

 

[Sandstorm]

Yup...I change my springs with every barrel. I have seen it way too often.

 

[LCazador]

I think your issue is excessive headspace too much bump. Along with that a hot load! How much bump are you using or this new brass?

No question the 270 wsm haul ass.

No sir, once fired brass bumped .002".

Check Hodgdon's Reloading data. Looks like, according to online info, you are over max recommended load with Retumbo.

Starting Load		Maximum Loads
	Manufacturer	Powder		Bullet Diam.	C.O.L		Grs.	Vel. (ft/s)	Pressure		Grs.	Vel. (ft/s)	Pressure
	Hodgdon	Retumbo	OUT OF STOCK	0.277"	2.740"		66.0	2,908	53,300 PSI		70.0C	3,071	63,000 PSI

I'll call Savage Monday to get a spring.
