Will Lapua 6.5 Creedmoor brass be ok without bolt modification?

[Kracken McGraw]

Please note that in the .308 Lapua Palma brass, the flash hole was smaller and would keep the decapping pin on my Redding S-Type bushing die. I contacted Redding and they sent me smaller pins by return mail. I removed the decapping pin, squeezed the end of the rod gently with pliers and installed the smaller pin and decapped thousands of rounds without issues since then.

Thanks for the Heads Up Turbulent T. Redding must of took note. I measured my full length Redding decapp pins this morning. 308 was .061 and the new 6.5 was .057 to .058

...and the new 6.5 was .057 to .058

Yep, says so right on the box label.

Lapua musta learned something after they got complaints about stuck decapping pins when folks started using their Palma brass a few years ago.

I believe ALL the small rifle primer brass they make has the smaller flash hole... but I could be wrong.

I ordered 50 Palma cases from Peterson Cartridge Co. a couple of days ago, will be interested to see if they follow the precedent Lapua established. Some members here have used it already but I haven't seen mention of this little detail.

When Hornady started making 6HAGAR brass under contract a few years back they went with a large flash hole for their small primer product at the instructions of the group behind that initiative.

Shoots just fine but then that's a case almost exactly the capacity of the 6BR too....

My point is that if you're coming from a LRP cartridge to an SRP cartridge of the same caliber and you're now piercing your SR primers, you have the wrong primers. The LR primer are all thick enough so as not to pierce; that's not the same with SR primers. Choose wisely.

And my point is if your firing pin does not have a radius on the end or the hole through your bolt head has excessive clearance it will crater or pierce any primer. I pierced 450's BR'4s and Remington 7 1/2's before I got the bolt head and pin taken care of on a 700 SA. No problems since.

Yeah, and I'm thinking one of two things is probably the issue:

1- Not all firing pins are created equal. I've not had a problem transitioning from LRP to SRP with my Panda F-Class action. In fact, at the Kelbly website, I have not found any reference to a smaller or larger firing pin. It doesn't mean it's not there, but I have not found it. At any rate after several thousand rounds with SRP Lapua Palma brass and no issues, I'm not concerned.

2- Maybe you're pulling the trigger incorrectly.

 

[DHuffman]

Yeah probably.

I always forget when I post on here chances are I'm talking about my experience with Savages and Remingtons compared to someone else's high end custom action experience. Kind of apples to oranges and since I have no Panda F class experience to speak from I would say you are likely right concerning what you're talking about.

I haven't had any troubles with the SR primers in my Palma's converted to 6.5 Creedmoor. All my primer piercing has been done with Lapua 6.5 x 47 converted to 6 X 47 because of a sloppy remington bolt channel and a savage in .223 which I believe was a firing pin not properly radiused.

Either way both potential problems were addressed on both actions and the problems resolved I can't really say it was one or the other on either.

I have a Defiance with the large firing pin. I've had no trouble yet. Norm told me it's 50/50. Some do fine others need to be bushed. Might depend on how hot you run it.

Stock Ruger Precision Rifle 6.5 Creedmoor, no primer piercings in converted Palma cases and now factory Lapua small primer cases with over 1800 rounds using BR-4, Fed 205, and Wolf SRM primers. I have loads that are medium to warm with 140gr class pills. I have shot a few dozen hot loads in testing with different powders and no issues. It will depend on your FP/bolt but I would go out on a limb here saying the Ruger bolt and FP fit isn't the most exacting out there.

I have a Defiance Stryker Ridge short action chambered in 6.5 Creedmoor. Really would like to purchase the small primer Lapua brass, but will it be ok without changing firing pins and adding a bushing. I feel like a lot of guys are just going ahead and just using it. What's your opinion. Thank you.

I've had two 6.5x47s, both on 700 actions. The one with the bushed firing pin shows no cratering. The one with the box stock factory bolt would crater primers badly.

That being said, I believe most custom actions are coming out of production with the small firing pin. My Shilen DGR, also in 6.5x47, came with the small firing pin and shows no cratering either. If your Defiance has the small firing pin I'm quite confident you will have no issues. Indeed, with minimal clearance between the pin and the hole, it's possible that even a large pin will present no problems.

As for me, I see no downsides to the small firing pin and all my rifles will have them from here on out.

I have a Ruger M77 6.5 Creedmoor, have always used LRP. Will I have a issue with using Lapua SRP brass?

Probably fine. As posted, it depends on the primer. I've had good luck with BR4 and Fed ARmatch in 6.5cm. I didn't try Wolf SRMs as they didn't have enough ass to run in .308 palma.

I've never had any piercing issues in Bergara or Rem 700s

 

[Bill K]

I shoot small and large primer Lapua brass in my 6.5CM with no issues, why do you think you would ?

 

[spudgun]

My Savage Model 12, 6.5 CM would crater and sometimes pierce my Starling cases using CCI SRP. Went to CCI #41 primers and all issues went away.

Yes I could have sent my bolt off to have it sleeved for the firing pin dia, but 4 years using #41 primers and not a problem.

My second Savage Model 12 has not shown this issue..

 

[White Eagle]

just go ahead and use it the way it is
you may have some trouble with lighting the charge may sound like a hang fire
what I did and it resolved that was to open up the flash hole's with a lyman flash hole champfer or deburring tool
all it is is a long shafted center drill looking thingy

Everyone I speak to about reloading for competitive shooting says Lapua Brass. With that said I ordered 300rds.
My question is with All the case prep that is done on every loading what makes Lapua BETTER?

The metallurgy Of their brass is made strong to handle higher pressure better, plus the immaculate workmanship on their brass.

So it’s a Stiffer Brass basically?
