[QUOTE="TOM H, post: 1143430, member: 306"] It really depending on how much weight you want to carry. I wanted longer barrel on my 280AI as I can do some longer shots here in Co. I got little smaller contour so I could have 27" barrel and still keep rifle under 10 lb and still have well balanced rifle. If I want with that barrel I can do 3100fps plus with 160gr AB and has 1/9 twist and it will handle 180gr Bergers. If I replace that barrel I might do 1/8 twist and kept same barrel length. When I had 280AI I also had 284 build long action and same barrel length as 280AI and OAL 3.228" same as 6.5x284 Norma. You can neck up Lapua brass and I think there some Norma 284 still maybe do 25" barrel and 1/8 twist be a nice deer rifle. I shot 6.5x284 Norma on a long action for couple years and with the bullets improving for 7mm is one of the reason I did 284. Well good luck [/QUOTE]
