    I'm looking to by a 7mm remington mag, i have a .270 win. I want to move up because ill be taking longer shots on elk and i can push out to around 700 yards and want to maintain energy at that distance, that being the reason wanting to move to a 7mm rem mag. How is the recoil on the 7mm remington mag as compared to the .270 win, Im wondering because i can get a rifle with a muzzle brake and such to reduce recoil for extra cash so im not flinching because of the recoil, im fine with the .270 win, so again how does it match up?

    There is a recoil calculator here somewhere which can provide numbers to compare.

    I'd guess it's 30 -40% more.

    Personally, I shoot my rifles a lot. Enough to develop a real feal. With a brake, the 7mag is comfortable enough to shoot extensively. Without a brake, the cummulative effects become uncomfortable.

    I would brake it, absolutely.

    Skip the 7 mag and get a 7stw. The total weight of the gun is a big factor in felt recoil. Flinching or getting a scope in the eyebrow is just poor shooting technic. I don't have a muzzle brake on either of my 458's.

    My advice is to borrow the biggest magnum that you can find and shoot about 20 rounds. Then all little guns like 7 stw are breeze to shoot. I'm not kidding. It is nothing to shoot 300 and 338 mags compared to full on 400 - 510 grain bullets. It is like going from a 3 1/2 inch 12 gauge to a 20 guage

    I have been hunting with a .270win. for several years. I just purchased a7mm rem mag. for the same reason you just posted. I am now saving additional money for a muzzle brake to reduce recoil.
    If you can get one with a brake already installed you should.gun)

    My research says that if you don't place the shot out of either one of those cartridges exactly where it should go you'll leave as many wounded elk in the woods with the 7 as you will with the 270.

    If you're gonna stick a brake on something I'd stick it on at least a 338 Win Mag.

    Member mentioned the 7mm STW, pretty hot round. Take a look at it.

    As far as the 7mm Rem Mag, I personally would break it. Like Grit said, it is going to have considerably more recoil than the 270.

    I'm like Roy. Why not just buy an elk rifle instead of trying to make something very marginal fit. For long range elk get a 338 something. None kick with a brake.

    Im in your situation. I own a Rem 700 ADL in 270. I shoot the heck out of that gun. It will probably remain my hunting rifle (as it will remain factory and light). I am waiting on a 338-378 Wby Magnum in the Mark 5 AccuMark :) It has a brake on it

    I'd go with LTLR - get something even bigger (300 Win, 338 Win, 300Wby, 340 Wby, etc) if you really want a long range elk rifle.

    Having said that, you could otherwise try for a heavier 7mm. My 7mm Rem Sendero is not a light rifle, and the recoil from it is very tolerable. This is especially so when prone. I do notice a difference compared to my "hunting weight" 7mm Weatherbys.

    I'm with the others on this one as well. Though either, with well placed shots, will get the job done. You certainly aren't leaving yourself much room for error. If you already hunt elk you well know how tough they can be.

    IMO, there just isn't enough gain to make it worth only stepping up to the 7rem mag. Like someone already said, find yourself a nice used 338win mag. Put a good quality brake on it and it will feel like your 270 or less.

    kc, you'll enjoy shooting that big Accumark. I had one just like you're getting and with the accubrake it wasn't bad to shoot. Never shot it without the brake as I'm sure that would have been another story. :)

    I just looked up some foot pounds of energy calculator. My standard 270 load is a 150 grain @3025 fps = 3047 foot pounds.

    I know that it can be loaded hotter but just use some of chuck hawks figures. 7mm Rem. Mag.

    his 7 mag 150's are 3221 FP's and that roughly ends up as a 5% recoil gain.

    I have never chronographed my loads for my 270, but this is the data, and I think they were around 2700 FPS, not 3050.. That seems high to me.

    150 Gn Sierra, 56.0 Gn H4831 (or SC), CCI Mag Primer, Winchester or RP Brass.

    If i remember right that is not the top but close to it.

    Go for a 338-378, 300 Gn bullet traveling over 3k fps.. that is just sexy.

    3025 fps 150 gr 270 is just 58.4 gr of 7828. reloader 22 and 7828 can get the 140's and 150's moving. Faster powders over pressure before you can get any speed. I tried some H - superperformance this weekend and 57 gr was only getting a 2900 fps avg.

    I have been shooting a Tikka T3 7RM and I won't lie, it packs a kick. All it took was a bipod and now it's a pussycat.

    600 yds 8inch group w/o a bench with 140 gr accubonds 63.5 gr 4831 and wlmr primers. You can still wound an elk with a cannon. Shot my elk at 550 across the river this year through the lungs and they turned to jelly- no worries about using a 7RM on elk.
