I am hoping the Hornady 143 ELD-X is going to perform, fingers crossed.
I sent Dave Kiff couple of dummies with the 143 seated with the top of the boat tail seated at the shoulder neck junction.
He ground the reamer for this seating depth and turned the neck down to .295". It is still a no turn neck, but tighter than factory. Dave's standard 6.5 PRC reamer has a .298" neck. Yeah Yeah, I'm an anal BR shooter.
For hunting here in the People's Republic of California, I hope the Barnes 127 LRX will shoot well.
I have built a couple of rigs with faster twists to shoot the Barnes bullets, they seem to work better with a faster twist.
Built a 25 Souper for my hunting partner on a Mod 70 Feather weight. Used a Bartlein 1:9 twist barrel, thing is a tac driver!
