True, but woofer is looking at a LW hunting rifle, not a bench gun, thus the hair-splitting.
Yea under those parameters I would take the 243AI there is not much much diffference unless your shooting high volume. I just debated im my mind what to chamber a new brux 6mm interrupted fluting sendero contour barrel in. I have reamers for 6x47, 6x284, and 243 and 243AI. I decded that I could not go wrong with 243AI. Now just to decide what action and stock to use. I am thinking just a trued 700 in a HS stock. I have decided to use the defiance action and McMillan
HTG I had earmarked for this barrel with a Rock creek ABS that arrived the other day. My stable of 6mms is getting unmanageable. I think I am going 243AI with both but may change my mind and do one in 6x284.
