Mag primers?

[BRTreedogs]

Intotally agree. My ES and SD went up a tiny amount with the mag primers but to me a more complete ignition on around 80gr of powder has to equal more consistency on target. That's what I'm testing next. I'd rather use my BR2s but I'm going to feed it what it likes.

Well my reply was for the OP since its his thread
He is only lightning off 57.5 grains.

And its just a general rule of thumb. If its already shooting well I'm just not sure chasing speed only is a worth while endeavor.

But thats just me.
