7mm RemMag vs .280AI as a hunting rifle

todbartell said:
maybe look at the 7mm-08 if you're flinching with a 7mm Mag. The 280AI will recoil about 20% less than a 7rm, 7-08 will recoil 45% less than 7rm, and 30% less than a 280

20% less recoil, but spits bullets at 10% slower velocity? What am I missing because in my head the math doesn't add up?

280 provides 10% less velocity than a 7mm Rem Mag? Math isn't your strong suit is it

Totally disagree. I forgot my ammo can once. Was 2am, 5 hours from home when I realized. Had to wait till Canadian tire opened before I could hunt but that sure beat driving home and back.

Edit - to be fair, the CT I went to (Vernon) probably had 280ai on the shelf, they had a very good selection compared to my local stores.

You went on a hunting trip 5 hours from home and forgot to bring ammunition?

So in factory ammo the 280 AI is actually faster? Interesting.
Click to expand...

Actually what you can take from that is those two particular rifles with those particular loads produce those results. Fast barrels and slow barrels are real. For example a friend and I have two identical t3 223's we used all components from the same packages and other than the brass being once fired in our respective chambers and neck sized only the loads were identical. The load produces 2987fps from mine and 3055fps from his for velocity averages Almost as much as difference in speed and way less differences in rifles, cartridges and components.
 
I've not bothered with a 280 or 280ai as the 270 and 30-06 do quite well under the hunting condition that they are used at... But given the original question from the OP the 7mmRM is more then a 280 so it has it's place under longer range field conditions. And if one studies ballistics - its not by much. So with the 7mmRM one is only going to fire one or two cartridges off on the longer ranges it can reach out too. So from the standing position, recoil does not seem to be too apparent / or different with a 7mmRM when comparing to a 30-06. So the 7mmRM gets the vote here over the 280 or 280ai.
 
The 7mm rem mag should be close to a 7mm weatherby, provided equal barrel length and freebore. The weatherby will trump a 280 AI and a 7 rem mag loaded hot should as well. The 280 AI is an excellent cartridge but the 7 rem has the advantage at long range. JMO
 
I have a 7mm rem mag, 280AI and a 7mm SAUM. If I could only pick one it would be the 7mm rem mag. I dont base anything on factory loads as I load my own. All 3 are very close to eachother with the edge to the 7 rem mag. I dont care about the belt, recoil or extra powder... Also, the 280ai and SAUM have more recoil than my 7mag as they are super light rifles... Just my opinion...
 
I currently have both a 280ai and a few 7RM's. I really like my 280a, it's easy to shoot and handle. Selling it in the EE right now so I can build another one on a different action.
The 7RM's i have in my safe are all destined for re-barrel jobs (338 Campfire & 375 Ruger). My previous one has already been turned into a 257wby.
 
I've owned a 7-08, 7x57, 7x64, and 7rm.
Still have the 7x57, 7x64, and 7rm.
7x57 is a nice recoiling accurate round.
7x64 has a fast twist allowing heavy for cal pills, pretty similar to the 280Rem case capacity.
7rm factory loads are pretty mild, it can perform much better with handloads.
The 7-08 was just a little too mild for me, 7rm is my favorite out of the bunch.
 
I personally can’t stand the new kool aid calibers that offer like 100-200 FPS more with a different casing. Stick to time proven stuff. Although a beltless 7mm mag or 300 mag does seem interesting, the rest doesn’t really
 
Either or... .280 AI is a well balanced cartridge and 7mm Rem Mag is one of the best hunting cartridges ever designed... you can't go wrong with either.
 
Over the years, I have owned a host of 7mm rifles: 7-08, 7x57, 280, 280AI, 7SAUM, 7WSM, 7mm Rem Mag, 7mm STW and 7mm Ultramag.
At present I own 2 - 7x57 rifles and one 7mm Rem Mag [M700, 1970's vintage]

The 7mm Rem Mag is one of the great chamberings, IMHO. Reasonable recoil, and stellar performance with bullets from 130 - 175 grains.
I prefer 160 grain bullets in the 7 mag, since at 3100 fps or so, they just do the job, even at extended range.

While one can chase 140's to 3250 or so, I prefer to use that weight in my 7x57's, since that case volume just seems to be about right.
Of course, all this boils down to is personal preference. Either chambering will do just fine for 99% of NA hunting. Dave.

I agree, I like the 140/150's in my 7X57's.
