Gentlemen, I am new to the forum so please forgive any mistakes I will make...I just spoke with a tech at Krieger Barrels and i can get a nice deal on a .284 barrel with a Sendero contour fitted & fluted, but he seemed to be concern with a 9" twist being to fast for anything less that 168gr bullets. Can y'all help me out and give any insight on it being to fast for the 140 Accubonds I planned on loading? It primarily going to be a 400 and under gun. Thank you all in advance!!
