My Rem 700 Sendaro SA (H&S stock) was a 22-250 . Now its a 6x284 chambered in a 26 " Hart Varmint contour bbl. Time to re-barrel. Want to reach out to 1,000 yds so I want to shoot the 107 gr bullets. Any bbl suggestions ? Thinking of a 28" Brux 8"twist #8 contour or their Remington contour . Is 28" to long ?
