7mm Rem Mag vs 300 Win Mag

Why not run the numbers (or “look at the charts”) using comparable bullets? Even lobbing softballs like Partitions, 200 vs 175, there is no practical difference between either cartridge.

If you start talking about retaining velocity using modern bullet design then there absolutely starts being a difference....
Cartridges are a lot more alike than they are different. Bullets matter more than headstamps.

Sidenote, got a lot of “tough country” over there in Saskatchewan where an elk or moose needs to be anchored right now? Just askin’......



Don't know much about Saskatchewan, do you.
 
Comparing two classic big game loads for the two cartridges :

7mm Rem Mag 24" barrel
160gr Nosler Partition @ 3080 fps
Recoil in 8lb rifle = 25 ft lbs
200y - zero, 2704 fps / 2597 ft lbs energy, 2.3" wind drift (10mph crosswind)
400y -17.4" drop, 2357 fps / 1974 ft lbs, 9.8" drift
600y -60.0" drop, 2037 fps / 1474 ft lbs, 23.8" drift

300 Win Mag 24" barrel
180gr Nosler Partition @ 3080 fps
Recoil in 8lb rifle = 30 ft lbs
200y - zero, 2703 fps / 2920 ft lbs energy, 2.3" wind drift
400y -17.4" drop, 2356 fps / 2218 ft lbs, 9.9" drift
600y -60.0" drop, 2035 fps / 1655 ft lbs, 23.8" drift
 
I've shot a fair amount of game with both . To be honest , they both kill well and are excellent rounds . I like to shoot the 7mm because it kicks less , other than that , there isn't much difference IMHO .
 
I believe both are great western rounds but freely admit I prefer the 7mm RM over the 300 WM for no real important reason. Likely only because I had one before a 300 WM. The big 7 does recoil less but that isn't my big concern personally. That said I am a Weatherby guy and therefore am bias to the 300 Whby Mag over either. I also love the 257 Weatherby. This is a awesome calibre for mice to moose. Cheers.
 
I shoot 140s at 3200 from a 7mm wsm. And 180s at 3000 and 200 gr at 2800ish from a 300 win mag. 300 is 2 pounds heavier to help with the recoil. I much prefer the 7mm due to seemingly alot less recoil with 2 pounds less gun. Never seen anything that liked to be hit with a 140 accubond yet. But I keep and use both.
 
The 300 hits harder at both ends. The 7 always seems to hit hard enough, and is easy to shoot.

This is how I see it.

Now, there are guys that like the recoil AND CAN HANDLE IT. Those are 300 guys. They can put the bullet where they want it to go. But, given the situation where a shooter might shy from the recoil, the 7mm Rem Mag has the edge.

Better to put the bullet in the spot, than flinch & miss.

BOTH are great cartridges!

On paper, the 300 is bigger, badder, faster, ect. In reality, I've seen large moose and bison drop when hit with a 7mag. For me, less recoil is a good thing when you're giving up nothing when it comes to meat in the freezer.

They'll do that when you spine or head shoot them with a 243 as well. I've never seen a bison or moose drop on the spot from any caliber with a heart/lung shot. If they do, you better reload quickly, because you didn't hit where you were aiming.
 
when i looked at the initial table that was posted in this thread I thought about the bullet weights that were tabled and wondered how close the 7mmRM and the 300WSM would have been. i've shot the 300 WM (180) and downed - barren land caribou at extended yardage and it perform very well. And I've shot moose at extended yardages with the 300WM (180) and it performed well. I've shot moose with the 7mmRM at a bit closer range (175) and it performed as needed. I've used the 300WSM (180) and it does an adequate job on Moose and Woodland Caribou. I know what a caliber does after I use it and see the real life results. Both are great cartridges and do a good job on the animals cited above. For Bison I would use a 9.3 x 62 (286) or a 45-70 with a 300, 350 or 400 grainer (or more) bullet. My experience has shown that the 30-06 is usually too much for Whitetail deer. Yet I've done it and seen the results. It seems to blow a fair size whole whither one uses a 150, 165 or 180 grainer at 200 yards or less. So crunching numbers is good, and so is studying ballistic tables. But it's the experience in the field that is most useful when determining - which caliber for which animal on a future hunt.
 
Modern bullets (be it super VLDs/ULDs or performance game bullets and hybrids) have made much of the ballistic arguments made today moot.

Honestly I've married up with a 7mm now, just due to this factor. 160gr AB kill very well, have a slippery disposition and the recoil is easily tolerable. My opinion is once I feel the need for greater than 190gr projectiles I'll move up to a 300.

I don't have that issue in NA so the 7mm is where I stay right now.
