Thread: Best rifle primers - a survey

Best rifle primers - what the pros use. A well done survey. Kind of interesting to read from the edge of the world where choice is a thing of the past.

Should be this: https://precisionrifleblog.com/2025/...-rifle-primer/

Should preface that this is based on PRS shooting.

Plenty of primers around

I have Fed 205, 205M, AR205M, 210, 215, CCI 35, 450, 250, WRE LR & LRM availible

I was surprised with Cals data that no one uses AR205M, certainly have proved a better option that CCI 450 in a few cases I used them in

Apart from CCI BR primers with the marking or primers that are not nickel plated (Rem 7 1/2), it's also difficult to tell what primers people are using externally.

I suspect a lot of that data is not particularly exact... 'Here is my favourite load, I'm telling everyone so they can run out and panic buy my preffered components!'

For example, we now have Vihtavuori (VV) primers circulating in Europe, but not for sale in the civillian market unless you have contacts...

I generally use CCI 450 or Fed AR205M, they both have thicker cups so cope better with stiff loads & big firing pins found in factory actions

If you are after maximum accuracy it is worth trying each to see if there is a difference

It is one of the very few instances when I have seen a difference in performance between primers
