Why not a 243 AI??

[bobinpa]

I have a chance to put together a 243 AI..... Long story short, the barrel is already chambered with very few rounds and I have the rest of the parts. It is a sporter weight barrel for a carry weight varmint rifle.
My question is what are the draw backs with a 243 AI? Will it feed from a factory Remington mag? I don't think they are known to be finicky to tune a load for but I could be wrong...

Please educate me.
Thanks

Mine is a single shot action so can't reply to that question but it is an easy button for tuning and mine is a custom build by ODCR that is very accurate.

243 AI is an amazing round. I have never tried to run it out of a factory BDL set up. Mine wears an HS mag and bottom metal and it works fantastic.

I have one on a M700 varmint. Feeds fine. Berger 105's and H4831sc shoot very well out of it

easy to convert to M5 bottom metal from PTG and AICS Mags

ODCR also built my 243AI. That was about 3 years ago and it still shoots Sierras, Hornadys, and Norma bullets so well that I'm always having trouble which one to load. It's mainly for marmots and coyotes so I expect it will last a few more years. In the 3 years I have had this rifle I have yet to trim any fired cases. My only complaint is that I can no longer shoot it as well as it can shoot. Old age kinda creeps up on you!

Looks like a good place to start? Older info, but may still apply?

No worries Bro. Happens to us all. Keep shooting.

There are no certain downsides, other than if you mind fireforming. You get extra fps and don't have to trim brass anymore. I simply prepped 300 cases and went on a prairie dog hunt. Fireforming made easy.

Mine is a Savage with a flush detachable factory mag; never had any feeding issues. I have several AI rifles and the only one I encountered any issues with was a 223AI using the Wyatt detachable box mag. I can only load 8 instead of 10 or the altered shoulder dimensions cause stacking issues.

This is good to hear. Thank you.

Thank you. I've looked at that page. A lot of good info there just like the rest of this forum. Appreciate it.

No draw backs in my eyes. Just make sure you have the correct dies first.

Awesome round and they feed out of most things

I'm curious. What are the correct dies? Should I assume there are different versions of an AI?

243 AI vs 243 win improved 40°. Are they the same or what’s different?

Hey guys. I have wanted to rechamber my 243 win for quite some time now and was wanting to go to 243 ai but am having a pain trying to find dies. Have recently broke 4000fps out of the win and am wanting more.

This side of the world we only "have" the 243 Ackley Improved and that's what we refer to as the 243 Ackley but the thread above is quite interesting

I've got one in a Rem. 700 BDL with a Broughton bbl. Feeds fine and is a varmint killing machine with 105 A max bullets. Do the build and have fun!

Thanks. That's good to know.

This one has a 1 - 10" twist. I think 70gr - 95 gr bullets should work great and I have A LOT to try and use.

The link in this is what I was talking about on the "Correct" dies. I believe PO Ackley used a formula for the case wall taper and the 243 Win 40deg Improved dies deviate from that, at least mine did. I have read others with the same issue but not sure if all of that companies dies were that way. Die company would not send me a copy of the specs and diagram of the die so I could compare to the reamer which the reamer company was more than happy to send. You may not have an issue.

I have two 243Ack and they feed fine out of the factory 700 mag with no issues
