YUP, SMOKIN!
SO, you got me thinkin on the P.O. Ackly improved! Tell me more!
Tac, the scopes we have available to us are a mixture of MOA and mrad
My Leupold and Vortex are MOA, my Zeiss, Nightforce and Nikon are mRad
my M1 Garand iron sights is yards, my Mosin and Mauser are meters
my Bushnell laser rangefinder has switchable scale
I grew up with MOA, and as an old guy am trying to convert to metric, but still confusing to me

Oh, BOY! Now I gotta visit Velsey! Darn You!
While it may not be the fastest thing out there, I do the the load data for the 180 gr, and even better, my fav, Swift Sirocco 180s should show a pretty good improvement! They seem to like being driven hard, so this might just be the hot ticket for me!
AND, as luck would have it, I have a nice little project rifle that could really benefit from this, BUT, it currently wears a 22 inch tube, so I gotta find some barrel length data to see what sort of loss i'm gonna see, if it's worth it or not!
Thanks @orygun!
How deep a throat did you get?
A lot of work and silliness to duplicate a 308 Norma Magnum.
. I didn't say the 308 Norma had an advantage, but the wildcat is a useless expenditure of time and energy.The only way I see the 308 Norma Mag having an advantage over the 30-06 AI would be the availability of factory brass. The improved 06 gets the same speed as the 308 NM with about 8 grains less powder making it a fair amount more efficient and providing less felt recoil. That is quite an improvement in my eyes. Ackley didn't hit them all out of the park but thank god for his endless tinkering because without his countless endevors, we may not have my personal favorite the 280 AI.
My rifle is a 77 MKII so it has the big ol claw for yanking brass outta the chamber. Just one of many reason I shoot this style of Ruger rifle.I see what your saying now! With so little of the original shoulder and no case taper, there is not very much "holding" the standard case. BUT, this brings up a new question, I wonder if a Controlled Round Feed Mauser Claw would make any difference, as it effectively holds the case against the bolt face ( sort of a second head space) and would in theory keep the case from moving forward. If your Ruger is the 77 type, I wonder if tuning the claw would change things for you? I'm digging around to see if this might be a possible solution!
I took nosler load data for both 308NM and 30-06AI using the same powder (imr 4350) and similar velocities. The velocity on both was out of 24" tubes. I input the data into a recoil calculator and got the following results. Load 1 is the 308NM and load 2 is the 30-06AI.

All things factored in, I know which one I would choose, and yes powder charge weight does have a very tangible effect on recoil. In this case 2 ft/lb.
