I have been doing some research on working up loads and i read on a particular website that they thought most 209 primers are too powerfull, as in pushing the sabot down the bore before the powder has a chance to push the sabot itself, resulting in poor grouping.

On the other hand, i have also seen tests done on primers where they measured how far a primer would push the ramrod down the bore. I'm assuming to find out which primer would push the farthest.

So what is it? Do you want maximum fire and push from a primer, or just enough to get reliable fire without too much push? I'm thinking along the lines of accuracy here.

Anybody have any thoughts on this?
