Hi All
Just curious as to what ES is good for a 284
I'm sorting out a new 284 barrel

15fps is the figure I hear to aim for in a long range gun.

Tim,

I have a 284 that has an ES of 21 over 10 shots,
I consider that acceptable.

Thanks for the feedback
I will see if different primers improve results

Tim,

I've found magnum primers generally don't suit the 284, even with slow powders.

I'm going to try different standard primers,federals and pmc (someone's old stock)

SD is more important than ES
Single digit SD over 10 shots should be your goal
RB

Acceptable extreme spread for 284?
