I am building a 243 ai on a remington action and a mike rock barrel. In order to shoot up to the 115gr bullets do I need a long action in order to seat the bullets out far enough?

Re: 243 ai action size
Its really close but you will be around .04 off the lands if its getting a normal throat in it just to get it in the mags at 2.8".

Re: 243 ai action size
So the .04 is probably going to be to much jump then for the 115 class bullets. I hate to go long action but it looks like I might have to then.

Re: 243 ai action size
If you're going to the trouble of using a long action for better cc then you ought to consider a 6mm rem AI. You'll be able to drive those bigger bullets faster than the .243ai.
Look on the angelfire 6mm Ackley site for lots of data plus a coupke of rifles on 6mmbr. One of which by Richard Franklin (although he drives the 87v at extremely high velocities)

Re: 243 ai action size
If you don't have a reamer yet, here is another option for a fast 6mm that fits in a short action. http://www.snipershide.com/forum/ubbthreads.php?ubb=showflat&Number=1456128&page=1

Re: 243 ai action size
I am pretty set on using the 243ai as the case. I am hoping the Rock 5R barrel in 1:8 twist will stabilize them. Has anyone ran the 1:8 twist in the ackley and if so how is the stability.

Re: 243 ai action size
Sendaroman was running them in his 1-8" 243AI, he had issues in the cold temps with them stabilizing.
I run the 105 class of bullets in my 243AI, but it's a 1-9"twist and that's what I built it for. I only tried the 115's just to see if they would stabilize in a 1-9", they didn't. A 105Amax at 3250fps surely doesn't suck though.

Re: 243 ai action size
I guess I need to talk to Sendaroman then. I will be running the same conditions considering he only lives about 70 miles from here.

Re: 243 ai action size
Load a dummy case to the length that fits in your gun and send it to the smith. There is no reason you can't fit the 115DTAC into a short action repeater.

Run a 1-7 or 7.5, the 1-8 is too slow in colder temps.
