Has anyone tried this. I just saw some at Brownells. I haven't heard of it before. It uses a small rifle primer. Pros. Cons?

Re: Lapua 308 Palma brass
before 6ppc,.308 cases with sr primers were loved from benchresters, because someone says the flame of sr primer works in a different and better way to ignite the powder_ I really doubt you can be disappointed with them, if employed in a adequate rifle and with adequate tlc on reloading tasks_good luck

Re: Lapua 308 Palma brass
I am in the process of trying the Palma brass. The main negative that I saw when researching it was that sometimes people had hangfires in cold weather. I live in Texas so I doubt it will be cold enough to be a problem,but to compensate I am using Remington 7 1/2 benchrest primers which are said to be relatively hot primers.
I had been using 47.0 gr of varget,F210m primers , in standard Lapua brass with Berger 155 vlds at about 2950 fps. Strangely it only takes 45.8 to get that velocity in Palma brass with the Rem. 7 1/2 primers in my 28in. Krieger 10 twist.Groups seemed comparable.
I changed because I was starting to get loose primer pockets, and I think the Palma brass will hold up better.

Re: Lapua 308 Palma brass
I've given thought to using this to form 6.5 Creedmoor brass, but haven't gotten around to moving it high enough on the priority list. Like the claims of the 6.5x47, I could envision/hope for a stronger case head when running hotter loads...
Thoughts anyone?

I was under the impression the idea behind the small primer was based on the philosophy that "the weakest adequate primer is best". It seems picking the hottest small primer goes against the whole idea?
Also, I think tge extra material surrounding the primer will handle higher pressure.

that,of course,has differet results on ignition times and behaviours of the various powders/charges_(for sure,some benchrester can explain that more properly than me)_good luck!

Re: Lapua 308 Palma brass
Mr.Langelius,if you know a better answer,I will be very interested to learn something more updated and, above all, understand if,in your experience, try to find s.r. .308 lapua brass can really worth the effort, regarding the accuracy_ with respect .

Re: Lapua 308 Palma brass
I had the rare pleasure of speaking w/ G David Tubb, and asked him about his experience with the smaller primers in .308 sized cases. Essentially he had tried them, liked them, and used them for some time successfully.
On later review, he determined that if one were to adjust the load somewhat, the same performance resulted from cases with large primers. He discontinued his work with the smaller primers after that.
His overall conclusion was that either would work equally well with good load development.
He also told me that he F/L resizes his brass for each reloading, which came as a surprise to me; but he believed then (back around 2002 i believe) that it worked better.
I currently use Lapua 6BR brass (opened up to .30BR) which uses the small primer. Load development is well along and it appears to be capable of very good accuracy.

Re: Lapua 308 Palma brass
I thought the idea behind using the small rifle primers in any case design is to limate as much of the influence the primer has on pressure/velocity as possiable. The idea being primers are a "uncontrollable ignition source" meaning you cant predect or adjust for a hot or weak primer, so by using a small rifle primer the primer has less of an impact on velocity there for less inconsistancy in velocity caused by the primer. This way if everything else is equal, like powder charge, NK tension, seating depth, case demision ect. the small rifle primer case could potentially have less SD and ES. Just how I see it.
But also on that note I shoot standerd LR primer cases in my 308 and get good #s, using 210m or CCI BR primers.
