What's your preferred brand of primers?

Not all primers deliver an equal spark and that's why there are variances in the velocity and es when you swap them.

Very informative! Thanks.

I use Federal match only.
I've had failures with winchester (blowing pin holes and scoring bolt face- faulty manufacture).
Federal are also known to be a "softer" primer, a few guy's I shoot with were having misfires with other brands in their lever actions, they did have after market light hammer springs that could have made the problem worse. Once they switched to Federals no more misfires

They are all different chasing some accuracy a powder and primer awitch helped in my swede. Now running russian Muron primers. Def a good help. Buys some and try em out maybe dont buy a whole crate at once. Used winnie smalls feds and cci large they all went bang but they can make a difference.

From my reading the least influence in velocity by the primers the betrer.

Yep, what Brett said. Federals go off when others won't.
