Re: 7mm rem mag vs. 270 win

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

Re: 7mm rem mag vs. 270 win

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.

Re: 7mm rem mag vs. 270 win

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.

Re: 7mm rem mag vs. 270 win

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.

Re: 7mm rem mag vs. 270 win

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.

Re: 7mm rem mag vs. 270 win

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.
