I'm glad the 6 & 6.5 are out. I have both, like the 6mm better & if it's hurt any one cartridge IMHO it's the 308 as premo ammo & components have gone down in price. Ive bought 1Fed 168 & 175 GMM bthp for just over $15 box back in the summer. For shooting steel the 243 & 7mm-08 went 400 more yards hypersonic anyway but theirs room for more with killing any calibers.
