I just recently started using Palma brass.
I tested 3 loads with the intent of only figuring out what it took to get me back to the velocities I run with regular Lapua brass.
Turns out it took .4g more.
Noticed that the groups looked like hammered dog poo while testing. Easily 1.5-2+moa at 200 yards.
I stuck a Weaver T36 on the rifle and was using some cheap, constantly settling bags for testing so I didn't think too much about the groups.
ES and SDs were not very good. When I got the load back to the velocity I was looking for the ES was 19 and the SD was 7. The lighter loads were as high as 40 and 19.
Today I shot a 1K match with the new brass and my groups on Target were less than stellar. I used every bit of the 10 ring with 22% leaking into the 9 ring.
I used Wolf SRM. I have 15K of them for the Service Rifle.
Apparently that may not be the preferred Primer.
The Lapua Palma brass has an extremely small flash hole. None of my decapping pins from small rifle dies or small pistol dies will go through it.
So, I need a hotter primer? Bigger flash hole?
I absolutely love the Wolf/Tula LR primer in standard brass. Usually this rifle shoots in the .5s with ES' of 9 and SDs around 5.
BR4 - too mild?
CCI450- magnum flame with a harder cup? Not usually associated with low deviations?
CCI400- standard flame and softer cup? Probably more flame than the Wolf but I know they will pierce in an AR at the levels we run those loads.
CCI-41- Hard as heck cup with a magnum flame. I tried the 34 once just for grins in Palma loads and it made a good load shoot like poo.
Federal- does anyone use Federal?
Remington 7 1/2- advertised as a bench rest primer. Flame too soft?
