264 Win Vs 7mmRM preference & why?

They are both outstanding, but both are limited by the factory 1:9ish twist rates. I would hesitate to get either one with anything slower than 1:8 twist if you want to shoot above ~0.300 G7 BC bullets.

I have both, in nearly identical rifles (Savage LA, X-Caliber 1:8 5R barrels), and the 264 WM has a moderate velocity advantage, and noticeably less recoil, when comparing the same B.C. bullets.

24" 264 Win Mag, 147 ELDM (~0.350 G7 BC) = 3050 fps
26" 7 Rem Mag, 175 ELDX (~0.350 G7 BC) = 2950 fps

The 7 RM does have a couple of bullet options that have significantly higher B.C. than any 264 bullets (e.g. 190 A-Tip, 180 ELDM, 195 EOL).

For me, the decision would be made based on hunting scenario. Up to deer, 264WM is about the best there is. If elk, moose, or walrus is on the menu past 400 yds, go with the 7 Rem Mag.

Yep, that's why I recommended a re-barrel. My .264 WM has a 1:7" twist.
 
Same here kinda. Bought a M-70 264WM Extreme Weather and rebarreled it to 264WM. Only 8 twist #4 contour Bartlein. 156EOLs @ 3100 do some damage. My go to. Righty.
 
I own both a 7mm mag with 140 ballistic tips and a 264 win mag with 140 ballistic tips, identical down to the tikka 26" preffered prefit 1-8" twist on both wearing 3-18x44 Z5's. For MY purposes axis deer out to 500 yds I can see the difference when hit with a 7 mag which hits harder for whatever reason. Recoil is about the same, velocity is about the same, trajectory is about the same.

Now this is where to me on several rifles I did notice loading was easier for the 264 win mag, to me it was more accurate and faster to find a sub MOA and consistent load. Brass is harder to find and more expensive for the 264 win mag, bullets in each have their unicorns but overall to me the 7 wins because of the way how I see animals just drop and die faster.

You cannot go wrong with either one…. But if you want something better…. 270 wby mag with a 1-8" twist!!

Aloha
 
I've always liked the idea of "gapping" calibers. If you're a 6.5/264 person it makes sense to skip the 7's and go to the 30's. If you're a 7 person it makes sense to skip the 6.5's and go to the 24/25's and to skip the 30's and go up to the 33-37 caliber cartridges for an appreciable difference in the power bands given a similar class of cartridge.

What's "best" is subjective to where and how you hunt… and also what's legal. For larger game like Elk many states out East implement minimal calibers like 27 caliber and up. While many might argue and have proof they've killed with smaller calibers that would be a discussion their lawyer would have to advocate for them on their behalf.

So I settled on 7's as my baseline and gap from there.
 
264 all day and 5 times on Sunday. Every 7 I have ever fired and there have been many, kicks like a mule so 7 doesn't always win. Better BCs with 264, again no 7 win. Only 7mm I have ever owned was an STW, good gun with a brake recoil was tolerable for light bullets (140gr ok, 160 175 not so much), but since I have been a .264 guy since my first one, a Sako Finnbear in 1975, I have no use for any 7mm and someone I met wanted the stw way more than I did so now its his to toy with. Small 7s won't do anything a 308 / 264 can't do and the big ones won't do what a plethora of 300s will do. Just one man's view!
That is funny... Your screen name is 340 Weatherby for everything, and you say a 7mag kicks too hard.
 
I am not a big fan of comparing apples to oranges. It boils down to personal preference and intended purpose. I have .264 WM built to propel the 156 Bergers, and I like it thus far. If you have had many left-handed 7MM RMs, why did you not re-barrel it to .264 WM?

Feenix; gave me a rebarrel idea here! Would you care to share more details on this setup like barrel length, twist, velocity etc?

Also do you have a rough estimate of barrel life if ran moderate?

While loading for both with the same projectiles are the powder loads about the same?

Mine is a budget build based on Savage LA. It has a 26" X-Caliber 1:7" 5R Sendero contour. Load development has not been finalized; I am just exploring with powders I already have open. As with anything else YMMV, with RL-25 and 33, I was propelling the 156 Berger 2950-3000 FPS . About barrel life, I have never paid attention to any of my rifles. Here are calculators that might help you with barrel life projection, https://pierrevanderwalt.com/elementor-3527/, and https://bulletin.accurateshooter.com/2008/10/spreadsheet-formula-calculates-useful-barrel-life/ Good luck!
 
Two excellent caliber, for medium game like deer, at medium ranges. ( 300 to 500 Yards)!! Either could be loaded to provide a flat trajectory with high BC bullets, and deliver sufficient energy to kill deer at 300 to 500 yards. Shoot them both at the range every week. Great Fun!! IMHO! For HUNTING, I would favor the one I shoot the best and give it the best scope I could afford, to help me dial in Elevation at those ranges. ( Ex; Leupold 8.5X to 25 X , 30mm Tube Windplex.).
