Best Barrel Twist For 280 AI (SAAMI) Up To 160 Accubonds (Hunting)

[Fuj']

A 9 twister will do but, if an 8.5 is available I'd snag it.

Would the 8.5 be too much for 150 BT''s and Partitions?

You'll be fine. The other thing to consider is them longer bullets
like Berger is making. Keep all your bases covered.

I've been researching the .280 AI for a month or so now, as it is what I want to build next. I plan to shoot the 162 ELDX and a 8.5-9 twist is recommended from everything that I've read.

I'm going to go with a 9 twist CBI in 280AI.

10-4, thank you. I grew up in Eastern Oregon so I know what a "sagerat" is. Are you near Burns, Vale, etc...

What length on the CBI? It seems I always read 24" is best but I think I'm going 22" in heavy sporter. I want to carry it for whitetail and Elk. Hopefully I would not have to clear out the barrel channel on my B&C Medalist much since it is currently holding a Savage 30-06 sporter.

You must be my brother from another mother.... I'm changing over from my trusty old 30-06 (111 action) and I'm going with a 24" Heavy Sporter as I will be putting a muzzle brake on mine (I don't like the recoil of my 30-06 as is). It may be a little longer than I'd like for carrying in the thick stuff, but the country we've been hunting for awhile now has a bit more "wide open" with shots ranging from 300-700 yards. I want enough GAS to get there with 1500 ft/lbs of energy still remaining. Heavy sporter will fit in my OEM plastic stock without too much sanding to open the barrel channel, so your's should be about the same process. My goal is to keep the rifle weight to about 9 lbs (Hopefully).

I don't live close to Burns/Seneca/Lakeview (I have to drive 4+ hours) but that is where I do all my hunting for Elk, Deer, and Sagerats.

Let me plant a seed of doubt...have you looked at 280 Sherman? They are some nice looking cartridges and give you a bit more.

Thank you sir!
