Nice rifle Taco! Which action is your rifle built off of?

[Biggerhammer]

The action looks to be about as Remington 700 as it gets.

Trued 700 with a fluted bolt, Broughton barrel, Timney trigger, McMillan stock. That rifle is far better than I am shooting a fixed 6x scope.

You might look at er shaw rifles . They are cost effective  and  work off the savage action plus there page is fun to play with.

Never heard of ER Shaw where are they located? Benchmark is literally in my backyard so I would most likely have them do work for me. Just looked at a chart that had 7mm Remington Mag at just slightly less felt recoil with 140 grain than a 30-06 with 165 grain.

I guess my biggest question is at longer distance which will have more knock down the 30-06, 280AI, or 7mm Mag?

I know the shooter (me) has a lot to do with the equation which rifle can I shoot better in all situations, but from a bench out to 400 yards which will be the most consistent?

The 7mm will always have more knockdown than the 280ai, it simply has more powder capacity. Some will say there 280ai is just as fast as a 7mm but to do that they have to run their 280ai's at a higher pressure than a 7mm.

As to which is more consistent, that would really be splitting hairs. There was a chart at one point from one of the bullet manufacturers in regards to inherent accuracy of cartridges. Essentially, shorter and fatter cartridges are more effecient and burn  powder more consistently. There is nothing set in stone as to what rifle is more accurate than another. Cooper sends those targets with nice little groups with all their rifles, not just 280ai's.

That's why there are horse races and we don't all have the same horse!

They all have their place, it's all Persenal preference.  I like fast cartridges along with super magnums but have no problem getting it done with the 6.5 Grendel or 6x6.8 SPC. I grew bored with factory offerings a long time ago. Then I grew bored with your basic wildcats and decided to tinker with my own and a good reamer maker helped.

I prefer to hunt with a different or several different chamberings ever year. One year it may be a .375 260gr Accubond at 3050fps the next a 6mm 90gr Accubond at 3000fps. It's what works for me.

One thing I do know Yorke is making me crazy with that .338-.408!!! I'm going to have to build one!!

Bigger hammer that is kinda what I am getting at. It's like having an old car, truck, or boat and wanting to tinker with it. What can I do now? Add a new motor, lift it, add a winch, tires, the list goes on.

I could go buy a model 94 30-30 and kill Deer the rest of my life with it, or I could tinker and have a really cool custom rifle. The end result is the same, the Deer won't know the difference!

In the 80's I had the itch for a spiffy, shiny over and under shotgun.   I bought a Winchester 101 Pigeon grade trap gun. I don't shoot league trap anymore but I do like looking at that gun.

Good luck with your purchase.

Get a barrel with a tight twist so you can run a 180/190 grain bullet.  If you are shooting 150 grains and under anyways... you are just hotroding a 7-08 which also usually has the rate of twist "issue".  Silly American cartridges.  We should have just taken the 7x64 Brenneke home and been happy.

7x64 Brenneke? Never even heard of that caliber what is the origin of that caliber? I have seen the 7mm-08 around quite a bit though.

I would have suggested another blast from the past, the .256 Newton.

Wait Dustin Ackley improved his BA to .280 in the winter leagues or what?

JK! That's just what pops in my head everytime I see this thread.
