My buddies 280 AI is a Gaillard. We found around 100FPS less?
100fps is easily within the range of different chamber dimensions, different lot#s of powder,or difference brass.

Bolting down the barreled action will not result in a significant difference in velocity.
An oversized chamber has more volume,so the same powder charge will produce less pressure in a larger volume chamber,which results in less velocity.A minimum spec chamber has less volume,so ,more pressure results,which in turn results in more velocity.

If you had a 7mm at your disposal I'd be interested to see what your results would be with a 160gr with 61.5gr of RL19
So what is your exact speed out of your AI & 7mm compared side by side?
Not even a reasonable attempt to prove your earlier claim.But then again,I didn't expect any different from you.
This is just funny, as you said the AI will do 150fps more with a 10gr heavier bullet. It's fairly common knowledge that the .270 can push a 130gr bullet to 3150fps. This would be one of those conclusions you talk about below.
There is no barrel length listed on the Nosler site,and your data including velocities,does not match the data given on the Nosler site.The load in Question is a load using R-22,not R-19.
Don't confuse the issue with facts that lead to reasonable conclusions.Only rem338win can draw conclusions,everyone else must only post direct proof.He can plainly state that Bell never killed a Dall with no proof whatsoever to back up his claim,but you can't post information that may contradict his claim without positive proof.He sounds like a government employee,probably dealing with regulations of some sort.They are always right,sometimes even if you do provide evidence that contradicts their conclusions.
You took the words right out of my mouth. This is the point I was originally trying to make. We are going in circles here.
There aren't many sheep along the Hudson Bay coast, but when I do a Yukon Dall hunt I will simply pack the rifle I had built to hunt any big game anywhere on the planet. My .375 Ultra carbine will drive a 260 gr Accubond at 2900 resolving any issues concerning trajectory, and this thing has proven to be varmint rifle accurate.
That is what I would take myself, but if I was making a suggestion for anyone else's dedicated sheep rifle it would be a 7 or .300 magnum or a .270, .280, or a .30/06 with a factory chamber. The .25/06 shoots as flat as a laser, but I prefer a bullet with more mass and the 6.5 the smallest bore I am happy with for big game, despite the extraordinary performance a pal of mine has exhibited with his .25/06s. The only wildcat I would consider is a .280 AI, and if it was my rifle I doubt I would bother with the outsized chamber. For those who like em, short action rounds like the .260, .7-08, or the .308 are tempting when chambered in short light carbines. The .284 or the 6.5-284 is best chambered in a standard length action.
A flat shooting rifle makes the long shots easier, but once you are in the field the cartridge your rifle is chambered for is unimportant provided you can shoot it well. A model 94 in .30/30 wouldn't be an ideal sheep rifle, but you can make it work.
The last time I was in the Yukon this Sako .300 Winchester with a 3.5-10X Leupold and loaded with 165 gr Ballistic Tips proved itself on the 500 yard rams at the Whitehorse range, but unfortunately I didn't get the opportunity to hunt with it on that visit. For the record, shooting off the bench is poor practice for an upcoming hunt.

I have to agree I will also be taking my 375RUM if I go after sheep/goat this year and my buddy that used to pack a 270 Win for years has now switched to a 375RUM as well.
Last year he encountered quite a few grizzlies on his hunt (yes all of our hunts are unguided) he said that having the 375RUM along definately made him feel more capable of dealing with anything that he had to deal with.
We're both shooting 300gr Sierra Gamekings @ appr 2775fps (98grs RL22) they have the same BC's as the 260gr Accubonds's so also have an awesome trajectory and are extremely accurate I have repeatedly placed 3 shots within 3" with this rifle/load @ 460 yards shooting from field positions.
I attribute this accuracy to the B&C reticle scope and a range finder...
My buddy uses a Leupold VX111 2.5-8X duplex reticle scope and a McMillon stock, I use a VX111 4.5-14X Boone & Crocket reticle scope and I will switch out my LSS stock and pop on a synthetic stock for this kind of hunt.
I've been to that range. Very nice!The last time I was in the Yukon this Sako .300 Winchester with a 3.5-10X Leupold and loaded with 165 gr Ballistic Tips proved itself on the 500 yard rams at the Whitehorse range
My buddy shot 1 6 point elk @ 40 yards and wasn't overly impressed with the performance the 6" exit hole out the off side rib cage didn't slow the elk down as quickly as he thought it should.
He shot another 6 point bull elk @ 80 yards in the neck driving the elk into the ground killing it almost instantly but the bullet seperated so he figured it failed.
I asked him at what point do you think the bullet failed he responded "when it seperated" I asked "did it kill the animal almost immediately" he answered "yes" I said "so obviously it did it's job and didn't fail if the animal died almost imediately"...![]()
He was in on a buffalo hunt last fall as well he is a bit more convinced now that these bullets hold up to almost anything he can do with them put 2 into a big bull I don't know the range bullets mushroomed perfectly.
I haven't shot any animals with the Gamekings yet I have been using my 300gr Partitions for shots within 300 yards, shot my grizzly last year @ 230 - 250 yards the Partition worked perfectly.
Nosler used a 26" barrel for their manual testing (like I said a fairly recognizable person from Nosler even confirmed that) which happens to be the same results they posted up on their site. Imagine that. And at what point in time was RL22 the only powder for the job? RL19, VV165, H4831, IMR7828 are all good powders not to be ignored either. I used the fastest loads from the manual in my quote. I figured you'd want it that way to be subjective.

Further more Bell never wrote about killing Dalls
Bell subsistence hunted in the Yukon, which I envy him for, but made his name for himself shooting in AFRICA. My original statement may have left the opening that you seem to be flogging to death, but after that I made it clear that the difference between Bell and O'Connor was that O'Connor made his living writing about chasing sheep (amongst other things) and Bell made his living off of ivory. I see no argument left there.
And what earlier claim did I make that I made no attempt to prove?
Bell didn't kill any Dalls)
