.243 AI

Going to rebarrel my .243 and was thinking heavily about an ackley improved .243.
Does anyone that shoots this have any load/chrono info on this round before I go for it?

Re: .243 AI

I would definately go for it if thats what you want. What will be the purpose?? For longer range shooting, most go with a 1 in 8 or 9 twist to shoot the heavier 105-115g bullets. They do a lot better past 500 yards then a 55g zipping along at 4300fps. Should reliably be a 1K getter for coyotes,chucks,pdogs, and probly would work on antelope/deer out to 700 yards, maybe 800. I would love to own a 243 AI and shoot the 105amax or berger VLD. Good little round. You should get some good advice from people who actually have had hands on experience with this round. I'm going by all heresay and from what I read. Good luck!

Re: .243 AI

I've had two and would definatly go the Ai rout , yo gain about 100fps in 24-26" barrel lengths but the case ife is WAY longer. Most of my load data got washed away in a huricane but I still have a couple books that arn't totaly ruined I dig them up.
I would definatly recomend the 1-8 twist unless you wanting to shoot light varmint bullets only.

What is it your gonna be asking of this rig?

Re: .243 AI

I would definitely go with a 1-8 twist barrel in the 243AI. I am shooting the 105gr berger at 3250 out of a 27.5" barrel. I have shot antelope out to 460 yds. Instant bang-flop....I have shot out to around 1300 yds with it now, and have had great luck with it. I even built the "little woman" one to hunt with.

Mine

Her's

Re: .243 AI

I have a 1-9 twist and it shoots the 105 amax ans 107 very well. Mine is a 30" Hart Max HV profile benchgun however the extra barrel length is really not needed. I can drive the 105 class bullets to 3450fps but they group better around 3200fps. Go with a 26-28 tube for a hunting gun your not giving up much. Use Lapua brass to save time prepping brass. Also forget the three groove barrels they will blow up the vld thin jacket bullets. Mine shoots the light bullets well also but after you shoot the sleek vlds you will never go back!

Re: .243 AI

I have 3 groove Lilja's on both of our rifles...so far, we have blown up any Bergers. I have driven them to just over 3300 with my rifle and not had any problems. I don't think that I would want to go any more. The A-max's definitely don't survive over about 3250. I will say that the VLD's seem to shoot the best around 3200-3250.

Re: .243 AI

Probably mainly a whitetail gun up to 500 yards. I've got a ton of 243 brass to use, but wanted to hunt whitetail with a little bigger than the 85's I'm shooting now. They do great but I would like a little more energy a little farther with the 100+ weights. With AI rounds if you neck size only do you need AI dies?

As far as 500+ I'm hoping the 300 RUM I'm getting together will cover my needs there!
