I get use to people wanting to argue semantics. It is like opinions!JE didn't "jump on you". He just corrected you. But, since P.O. Ackley was actually dead before the .260 Rem ever came around, technically NONE of them are "AI" cartridges, they were just designed using his improvement style and dimensions. They are all simply .260 Rem Imp. I still call it a .260 AI, even though it's a misnomer. It's not a big deal, but sometimes we like to discuss and argue semantics.

Runnin 24" barrel and 1:7.5 twist but a 20" tube would be a solid selection too, especially if this is a mountain type rifle where wieght is a big factorI'll stick with my 20" barrel and 1:7.5 twist.
That's why I said long action, the 260ai and sweed both belong in one for max effort.The Swede gets a little tight in a short action with long bullets.
View attachment 139924 I have another thread going about a 260 IMP I built. Look for 260 Remington AI. I stand corrected on the "AI" because it is only 30 degree shoulders and JE Customs will jump on you for being not correct. I found my sweet spot is 43.5 gr under a 142 SMK. My 5 shot group was 0.38 MOA @ 100 yds. This was unfireformed Peterson brass. I'm going to start playing with seating depth on fireformed brass to see if I can tighten the groups up even more.
Sorry If you thought I was jumping on you. I was only offering up what I know. I cant jump on anyone because I have been wrong many times and can only offer my experience in some things . When we post on this site, we often get corrected. Most of the time it is Informative and constructive. Some time it is a personal attack but not very often.
I am always interested in a different opinion. (That's how we learn)

I'm not worried about it Sir. I'm wrong most of the time myself.Sorry If you thought I was jumping on you. I was only offering up what I know.

I am planning to Ackley Improve my Remington 260. I've read and considered all the arguments for and against the AI. My question here is what is the most ideal barrel length and twist to achieve the maximum accuracy and velocity. I realize there will be a process of selecting powders and bullets, and fine tuning them, but I really want to hear your tho'ts about length and twist.
264 sends 130s well above 3000. 140s at 3200 is fairly common in a 264Your speeds sound like a .264 Win Mag, except using less powder. I loved my .264, but it seems it isn't too popular even these days.
My question is why AI the 260 Rem when you only shoot out to 350 yards? You have to fire form your brass so you will go through it twice as fast. I'v hunted w/ my 260 Rem sense 1997 out to 1400 yards. You get less than 50 fps when you AI the case. Even if you don't AI the casing you can get around 2850 FPS from a 20" barrel. That still has enough punch to take white tail all day long at 1125 yards with a 140 grain VLD Berger Bullet. Iv surpassed 1400 yards on coyotes.I am planning to Ackley Improve my Remington 260.
