6 XC for now. Very wide flat tune node from 39.5-41.5g of H4350 using 105-107g bullets...tiny, tiny groups. Tubb is making some very, very tough brass($69 per hundred)
115g at 3050.
R#17 jacks speeds up 100 fps.
I use 7 1/2 in the Small primer brass and Fed 210's in the large rifle brass.
Also made brass from 308 brass, still shot small groups 2's and smaller, neck trim and turn are involved
Finishing up a 6 BRA now.
The 6 Dasher and 6 BRX produce 243 Velocities with 10+g less powder.
The 6x47 Lapua is a hands down winner, NO down side.
