Primer sizes for.308 ?

[NobullSKS]

Researching.308 brass before a rifle purchase..... hopefully it will fall through.

Midway has .308 brass with selection of small or large primer pocket size.... the LRP are sold out; so that’s what I probably need

Can someone break down the difference, in terms for a dummy.... me....?

I have never seen SP .308. Not saying it doesn't exist, just never seen any. I have seen SP 6.5, apparently some believe they get "better" ignition from small primers. I would avoid it just to keep things simpler.

These guys have once fired .308 in stock now.

These guys are in Moses Lake, I support them when I can.

SRP 308 exists, Peterson makes a variety and is headstamped as such. C.I.P. says they are to be large though.

So you don't want the rifle but you're still researching brass? Do please explain...

I wondered about that as well. I guessed he meant GOES through.

I don't know?... That rifle you really want, shouldn't afford? What are you going to tell the wife?......

 

[BigDog67]

What I tell her is, "If you want to come out and stand on the road/street and put up with the driving public, THEN you can tell me what I spend my money on." It usually doesn't go beyond that.

Learned something new here. Never heard of small primer 308 before.

I use small rifle primer in 6.5 Creed, so it seems plausible.

I talked to one of the people that shoots a Palma rifle and he said he uses the small primer .308 brass.

 

[BigDog67]

Seems REALLY stupid to me, but I'm just a hunter with 60+ animals in the last 43 years. WTF do I know about primers??????

 

[thorborg]

I could just as easy use large or small primers.
But...
Mixing primer pocket sizes for the same brass requires too much attention to details that one just doesn't need worry about.
I went down that road with the 45, ultimately labeling it as Irritating and stupid.
As 99% of my brass were large primers, I gave away the few hundred 45acp small pistol primer brass I had.
I hope God forgives me for screwing with the other guy's life.

 

[BigDog67]

I keep the small primer .45, but I have Blazer boxes to keep it in. When I shoot, I shoot all one size or the other NO MIXING. But I don't need that with my rifle brass. .223=SRP, everything else=LRP/LRMP.

Well good news on that...... I was waiting to confirm logistics with seller. Turns out the seller provided me a wrong telephone number in private message after short PM here. Ooooop. Someone got a boarder line impatient text message. Suppose to meet and start transfer Sunday. Woohoo

There was some confusion in contact with seller here. Good news.... was able to get to an agreement and starting transfer Sunday. Woohoo
Found everything I need on the shelf at local shop in Renton. Everything but dies. I’m gonna have to be patient on that one..... but was able to get 200 LRP and powder. Good shop

Pretty good read here:

Small Rifle Primers vs. Large Rifle Primers

A close look at using small rifle primers rather than large rifle primers in reloading cartridge cases where both are offered; testing shows size matters little, with a few exceptions

308 Match Brass - Small Rifle - Brass Cases

"The .308 Match is our small primer version of the .308 Winchester case. Many competitive shooters prefer the consistent velocities produced by small rifle primers."

 

[NoMeat 2]

Remington made 308 Win. brass with small rifle primer available in the 80'S to accommodate match shooters, and cases to form 22BR, 6mmBR, and 7mmBR cartridges for "New" XP100 Pistol, before they actually provided factory formed brass (spp). Large rifle primers are most common in 308Win

IMHO......

Get the brass made for the Large Rifle Primers. I've never tried brass for a .308 Win in small rifle primers. BUT....knowing the confusion that it could cause. WELL...just like with the .45 ACP brass.....IMHO, stick with the "standard" (large primers).

As for what primers (if you've decided to go with Large)?

Well, now you should be doing research as to what powder you will be using and what the books says is appropriate with that combination. Hint: Just like with some women.....some powders prefer magnum.
