7MM Rem Mag vs 300 Win Mag

[jyerxa]

Oh you will never get a fair answer from me.  I've had my 7MM for 30-40 years. And that's that.

I saw not to long ago RBros was messing with basically the same thing. I can't recall what his was labeled, mine is the 7.21 SAGE.

Rbros is called the 7mm Rogue

Getting a new rifle for deer and elk.

Pretty much narrowed down to these two calibers.

Why would I pick the 300 over the 7MM?

Thanks!

+1

Can I ask what your thought process was to narrow down to these two calibers?

7mm fan here. 
My 30+ year hunting partner is a 300 fan.
We both have 2 each.
Neither one of us have ever had an issue with animals hitting the dirt.
Flip a coin......

I enjoy the two so much, I crossed the two with a custom reamer I had done, it is bases on the .300 Win Mag case necked down to 7mm, less body taper, shoulder angle change and neck dimension lengthened and a "Secret Squirrel" throat.   I saw not to long ago RBros was messing with basically the same thing. I can't recall what his was labeled, mine is the 7.21 SAGE.

Interesting....is that why you asked PTG for my reamer print after my original post?


The 7RM built properly will outshoot the 300WM in longrange.  In most hunting distances it really is a wash.  The 7RM has less recoil, the 300WM makes a bigger hole.  Take whichever you get the best deal on.

I was doing the math on the throat, asked for several wildcat reamer throat dimensions. Your targeting the 180's VLD's. I was looking for a happy medium to work with the 160 Acccubond as my first choice and possibly the 180's. Besides the 6.5-284 Neck is a perfect length and one doesn't need one longer. Other than the throat, your knocking on the Mashburns door, kind of like a Bill Alexander thing.

It's close to a mashburn but more capacity.  The neck is different along with our throat design.  I played with the mashburn a lot and the data it provided helped design my case.  Trust me, it's definitely not a copy of the mashburn.  The throat design also has a patent pending on it.  Part of the reason it's proprietary.

I have used both alot. When I have chronoed factory loads I have never had a 7mmrem mag come close to the published specs. I think any difference in felt recoil is more in gun design than cartridge. generally speaking a 7mm shoots a 150 grain at the same trajectory as a 300 shoots a 180. My 300 loves winchester failsafe, published at I think 2960 fps, chrono out of mine a 3025 avg. deviation of about 25 fps.
either will kill any animal in North America handily, I will never bad mouth a guy hunting with a 7mm however I shoot a 300.

In the eyes of the reamer builders " Proprietary  " is a simple is saying " Proprietary  " and POW! Proprietary is typed right there on the reamer print. It's fun to play with different cartridges and bullet diameters. Angles, throats and such but in the big picture, it has been done so much by so many that many are close to another or performs so close to other Chamberings that the difference doesn't really matter. But then again we wouldn't have horse races if everyone had the same horse, what fun would it be on the big firearms track if we were all running the same chit.

I have both, the only advantage I see one over the other is the availability of the 300 win mag ammo over 7mm mag.
More places, have more 300 win mag options.
Both are great calibers, buy one of each

Great advice.....   and thanks all.

I decided to just buy another 7MM so that I don't have to keep track of yet another caliber in the safe.

Happy shooting to all!

[DBHAWTHORNE]

I think you will be happy with that for sure. Which one are you going with?

Savage 111 combo with the Nikon BDC 3X9.

Nothing too fancy, but hey, I'm a working man.
