[QUOTE="Longtooth32, post: 1457767, member: 89326"] How did you determine a .145" freebore? Are you necking down 6.5x284 brass? Do you recall the outside diameter of the neck to make it a no-turn neck? I believe you may be slow in your estimation of the velocity that you are able to get with the 131 Blackjack. I am getting almost 3200fps with my 140 Bergers and almost 3100fps with my 150 Sierras in my 6.5x284 with a 28" carbon Proof Research barrel... TIA [/QUOTE]
