It's a off questions but I have had a few 243 ' s and have sold them and now I questioning building one but I already have a 22-250 Ackley and a 6mm Ackley, so do I need one? The 250 has a 1-12 twist and the 6 has a 1-8 twist. Now my dad swears by them !! And I have been trying to take that into consideration being since he has had them his whole life ( ultra medalists, vixion, 40X ) just seeing what you all think. Thank Caleb.
