I am trading for a M77 Hawkeye in 7mm Rem Mag this week. I currently have a 7mm-08 and 30-06 in that range so I think a 7mag wouldn't get any use but neither will the 270wsm that i am trading. The difference being that I can turn the 7mag into something I want, plus I like M77's and just want one.

So help me decide what would be cool. I hunt in Texas only and thats not likely to change. So whitetail, hogs, coyotes and varmints are hunted on my place. I dont see myself replacing the 7-08 as a whitetail rifle so I want this rifle to focus on something else. We do have a "texas mountain" on our place which would allow as long a shot as you can see. So I do have some interest in something that can drop a hog at long ranges. That said what do yall think?
 
Both choices listed were on my short list. Im leaning 7mm STW because it adds a long range caliber which I think would be cool. Now I will just have to figure out how to use it.
 
I have an idea. Why not leave it a 7mmRM? There's nothing that you could turn it to that would be more useful than that.
 
.338 Win Mag or .257 Weatherby. Those are above and below what you are currently using diameter wise. The Hawkeye is a relatively light rifle, so in .338 it will bounce around a bit. The .257 is a pretty decent long range cartridge although it doesn't carry a lot of bullet weight. Still darn effective though, and it should work perfectly in a Hawkeye.
 
Well, if you don't want a bruised shoulder from all the heavy thumpers why not get a .25-06 Rem? Easy recoil and can be used for just about anything in the US. Heck, you have a .30 cal, 7mm now the logical choice is a .25 cal.
 
7mm STW ==> Belt

7mm Dakota and 7mm RUM ==> No Belt

The choice is clear to me (if you stick with a reaming of same barrel), and it ain't 7mm STW! :)

The OP states that he is rebarreling the rifle not re=chambering it. With the super duper 7mm's you will much better off re-barreling with a longer 26-30 inch tube rather than re-chambering a more than likey factory 24 inch bbl.

The rifle he is getting has a magnum bolt face of .532" while the 25-06 uses a .473" bolt face so it would require getting another bolt if he were to re-barre to 25-06l. Now the 257 WBY will work and is a fine flat shooting cartridge.


TXHORNS, I have to ask....do you handload? Some of these cartridges mentioned are expensive to shoot and factory ammo doesnt have a big selection and good LR loads are very limited. This is a factor when considering LR type shooting which requires a great deal of practice to be proficient. Handloading is really the way to go as you can taylor the loads to suit your needs....... just my $.02


While lacking extensive bullet choice, the 270 WSM certainly isnt no slouch, my Sako spits 140's out a tad bit over 3200 fps. Shoots fairly flat without a lot of hoopla, kinda like the 7mm RM .
 
i cannot think of a more versatile, all-purpose for every situation, kill 'em all kill 'em now whenever and wherever found at whatever range rifle than the 338 win mag.

i think anybody who is serious about rifles must a have a select few chamberings, and the 338 win mag is most definitely on the list.

congrats on your new 338, and good luck!
 
I think it would be more cost effective to sell the 7mm Rem Mag rifle and buy another rifle in the caliber you want.

Maybe not as "interesting" but more cost effective. ;)
 
I've done two from a 7mm Rem Mag, one a .264 Win Mag, the other a .358 Norma. I like em both, but since you're in Texas, do the .264. I've taken 3 elk with my .264, deer and antelope too. It's a good, all around chambering, and won't beat you up as bad as the Norma.
 
Get rid of the 30-06.

You can share bullets between the 7's. Load the 08 for close range, and mag for medium to long distance.

Did you have to wear welder's goggles when you set that beast off? Does the manual tell you to scream "fire in the hole!" when you pull the trigger? Does the Forest Service you tell you to keep that thing out of the woods on hot, dry days? Do you still have eyebrows? Can it fire grape shot? I could go on . . .

Oh man, you made me laugh harder than I've laughed in 3 months...

Don't know

I'm not sure I'd change anything.

But I really do like that .264 Win. Mag. idea...................
 
What is the reason for getting rid of the 270 WSM, ammo cost? You have to know that the 270 WSM is a long range, laser-like killer in its own right. It's easily the equal of the 7mm Remag and 264 Winmag.

The OP is wanting to re-barrel a 7mm RM. I suggested the 7mm STW because it's an awesome cartidge, AND it shares the same bolt-face as the original rifle; he wouldn't have to rebolt the gun. As an extra advantage, you could simply ream the chamber of the 7RM to 7STW if he decided not to re-barrel the gun.

The .264 WinMag is a a good suggestion as well, as it too shares the existing bolt-face, as does the 338 WinMag.

The .358 Norma Mag, .257 Weatherby Mag, .25-06, 7mm Dakota, 7mm RUM, and .270 WSM suggestions will all require a new bolt or re-working of the bolt-face.

The .358 Norma and .257 Weatherby won't require any additional bolt face work.

I'll take your word for it, although the case head dimensions do differ (.530 outer rim, .455 crown, and .05 rim thickness as opposed to the existing .532, .480, and .05 of the original). I've never re-chambered the 7 mag coming or going.
 
Before you decide what caliber, you need to ask yourself "What job?" Of course, that's assuming there is some planned practicality involved. If the caliber choice is for sheer entertainment value, your caliber choice becomes very easy. Simply pick a caliber you want to be entertained by.

The 7mm Remington Magnum uses a magnum diameter rim on a belted magnum case designed to be short enough to use in a 30-06 length action. The magazine rails are opened up wide enough to feed belted cartridges. That will limit what you can re-barrel the Ruger to. (However, it's possible the Ruger Hawkeye action is magnum length.)

The Remington Ultra Mags may be too long for the action. The Winchester Short Mags and Remington Short Ultra Mags are designed to work in 308 length actions.

So your choices are a bit limited to 264 Win Mag, 7mm Rem Mag, 300 Win Mag, 338 Win Mag or their ballistic twins from Weatherby.

However, belted cartridges offer no advantages and are a waste of magazine space. If I were to re-barrel a 7mm Remington, I'd use a caliber using a beltless case with the correct rim size.

If it were me, I wouldn't trade the 270 WSM for the 7mm Rem Mag. I'd trade it for a 204 Ruger, 223 or a 22-250. If I had to re-barrel something, I'd swap the 270 WSM for 308 length action an build a 22 Cheetah, (or a 260 Remington if I didn't want a wildcat cartridge) and do some long range precision shooting
 
Kentucky Rifleman, the OP already owns a 270WSM, the question is why trade it for a 7mm RM.

As far as re-chambering a Ruger7mm RM Hawkeye to 7mm STW, lot's of luck, the action is not long enough to handle a full length H&H case. Even if is was doable, again I would'nt suggest doing it on a 24 inch tube, it simply needs more barrel to burn the large amounts of powder.
 
From the Ammoguide Interactive rebarrel conversion guide:

Base Parameters:
Start with 7mm Rem Magnum
Keep the bolt face unchanged
Keep the magazine length -- this is the limiting factor
Replace barrel entirely (not rechamber)

The acceptable cartridge choices are:
6mm Mach IV
264 Winchester Magnum
6.5mm Remington Magnum
275 H&H Belted Magnum
338 Winchester Magnum
350 Remington Magnum
375 American TR
458 Winchester Magnum


I vote for 458 Win Mag

What? Are you skeered?
 
We do have a "texas mountain" on our place which would allow as long a shot as you can see. So I do have some interest in something that can drop a hog at long ranges.

You just bought a 6.5 Remington mag.:evil:
or a 264 Winchester mag:D
