2,750fps from a 7mm-08 with a 160gr bullet is dreaming. Unless you have a 29" or so barrel.
You'll need to go up to the .280 Rem and a 24" bbl to get that velocity. The 7mm RemMag was developed to get 3,000fps with a 160gr bullet, and usually "just does, barely" from 24" bbls. Many lot#'s of factory ammo I've chrono'd for friends haven't broken 2,900fps. Most in past 5yrs have though, largely due to the ammo makers having to be more honest with cheap chrono's in abundance!
Just this afternoon, I was tinkering with some 150gr Nosler Bal.Tips in my 20" bbl'd Rem Mod-7 in 7mm-08.
Bear in mind that my rifle has a "fast" barrel with a tight and short throat. My velocities are often equal to the data barrels in most of the manuals with equal charge weights. My maximums are usually a tad under, as well.
I was able to get a top velocity of 2,740fps @ 25' with a 150gr bullet, over a max load of H4350. I was just starting to get a little drag on the bolt lift, and very slight cratering of the primers. Just about what I see from most factory ammo.
2,650 is do-able with the 160gr bullets,and is not exactly tossing Nerf balls. A gunsmith friend who built my custom .257 Roberts back in the early '80's had a rifle he had built on a German G33-40 action in 7x57mm. It had a 20" bbl and a Birdseye Maple Mannlicher stock. He had to send back a Ruger m77 in .338 back to Ruger because of a bad barrel, a week before he was scheduled to go to Alaska for a Moose and Bear hunt. The little "7" got the nod to go.
He subsitiuted the 160gr Nosler Part. for his usual 160gr Sierra over a stout load of H4831. (The OLD stuff, he bought about a ton of it when it was ~2.00lb). We speculated he was getting a tad over 2,600fps then. Now I'm fairly sure he was, but not 2,700fps.
He shot both a nice Bull Moose and a fair grizzly with the "dandy" little 7mm. He got complete penetration on both, and got DRT kills.
With the "little" 7's, bullet selection is the key. Even with the Nosler 140 Part., you're going to usually get complete penetration on broadside shots. My brother has killed 4 elk in past 6yrs with a .308 shooting 150gr Noslers. He has yet to recover a bullet.
I debated for 6 years whether to get either a .260 or the 7mm-08 I'd been wanting since 1980. When I had the money and opportunity, it was a 7mm that "popped up". So far, 6 deer have fallen to it during "bullet testing" for next years elk hunt. Softest 140gr bullet I've seen is the Sierra, followed by the Remington Cor-lokt. The Hornady 139gr SPt. seems a bit "harder".
With a little luck I'll find out what the Nosler 150gr B.T. is like, in E. Alabama later this week.
I plan on using either the Nosler 140gr Part. @2,850fps, or the 150gr Part. at 2,750fps for the elk trip. However I'm "bugged" by the 140gr Barnes 140gr Triple-shok. But I just can't bring myself to buy 80cent bullets and shoot most of them into dirt in loading development.
If I was going to be hunting thick timber, I believe I'd have to suffer and lug the .338 with 250gr Noslers! But walking 12-14mi. a day at ~7,000-10,000', I'll go with the "little" 7lb 7mm-08!
BTW; the #1 cartridge in Norway for Moose "taken", is with the 6.5x55. Number of one shot kills is only exceeded by the .300 WinMag, and then, only slightly.
Shot placement is much more important than diameter or ft/lbs.
