BUFFALO BORE PREMIUM 7MM REMINGTON MAG. SUPERCHARGED AMMUNITION

The 7MM Remington Mag. is a super useful North American big game cartridge. I have a personal bias when it comes to cartridge usefulness/effectiveness which I will discuss here at some length. Many folks believe the 7MM Mag. is a super elk cartridge. I don’t. I’ve killed and seen killed, numerous elk with the mighty 7 and it certainly will kill elk, especially if your ammo selection is proper.

So here’s the deal regarding killing elk with a 7MM Mag
If your task is to simply kill a meat bull, which is usually a younger/dumber bull of 4 yearsage or less, the 7 Mag. is very capable, but I have killed close to a hundred bull elk in my life, some of which were older than 15 years. Once a bull reaches about 8 years of age in this steep, hard, cold country, not only will his bones be twice as thick as a young rag-horn bull, but THEY WILL BE FAR DENSER TOO. His skin will be twice as thick, literally. His muscle mass will double a younger bull. He will rarely if ever leave the cover of trees in daylight, so when you do get a shot, it will likely be at a bad angle where you can only see part of the bull in timber and require at least a few feet of penetration and a running shot may be the only shot you get!!! Young bulls will go into the open in daylight and they will tend to stand still and eat for a while, but older bulls stay in the heavy forest unless it is night and they NEVER stand stationary while awake, broadside and wait for you to shoot them in the middle of a pretty meadow, like you see in the hunting magazines, so if you are a trophy hunter, you need ammunition that makes a big hole and penetrates deeply for those big tough, smart bulls. We can make the 7 Mag. penetrate deeply through bullet design choice, but it will never make the size hole of a .308 caliber magnum or a .338 caliber mag. I’ve killed at least 5 dozen bulls with a 340 WBY or a 338 Win. Mag. and the other 4 dozen have been killed with about everything else you can imagine. Additionally, I have guided many dozens of hunters to their bull elk, so I’ve seen many cartridges kill many elk and that has left me with some opinions.

Spare me the complaining emails please on this next part of this discussion, as some readers may think it is an un-sportsman-like discussion, but that is likely because they have never done it and don’t understand it…………….Hunting giant old bulls (and many of my bulls have been older/bigger) in dense cover and taking the only shot they normally give, which is some stage of g-o-i-n-g a-w-a-y, requires raking, quartering or straight away shots. I’ve taken several big old bulls with poor shots, but in all honesty, the shots were not poor, because I was using bullets designed to do that job and I was always using a .338 cal., .375 or .458 cal. bullet for that kind of dark timber, moving shot. I’ve never lost a bull I shot up the butt, in the hips or the guts, as he was darting through dark timber, with a 338 cal. or larger bullet designed for deep penetration. (Normally Barnes TSX or Nosler Partition bullets) No matter how good the bullet design, I would never shoot an older, tougher, bull up the butt with any 7 Mag. load……..the bullet simply is not big enough to be effective as it needs to be for these circumstances. If you are going to use a 7 Mag. for elk hunting, you need to be able to pick your shot precisely and the 7 Mag. will suffice nicely, but you'll not find me hunting giant old bulls in the heavy timber with any 7 Mag. load! Yes, I have and will hunt them in semi-open country with a 7 Mag. and proper ammo.

As of this writing, (02-2018) we are going to (for now) produce four different 7MM Remington Mag. loads and I will write a short tech paper for each load explaining its design and intended uses. I see the 7 Mag. as a fabulous long range deer/sheep/goat/black bear cartridge, that serves the dual purpose of an elk or bull moose cartridge ASSUMING PROPER AMMO. The 7 mag. ends up wounding a lot of big game animals and here is why……………the typical 140gr. bullet is doing around 3200 fps at the muzzle, so if you fail to choose a tough controlled expansion bullet design, the softer bullets tend to over-expand or rupture and not penetrate deeply enough……..on deer, this is not normally a problem as they are thin bodied and you do not need tons of penetration to kill them, but on big elk, big bear or moose, your 7MM Mag. bullet, had better be tough enough to not over expand on those close shots, but still have a soft enough nose to expand on a 500 yard shot when the bullet is going significantly slower. Hypervelocity cartridges always have bullet design issues…………..

Each of these loads was designed for specific uses and as we release each new 7 Mag. load, this tech paper will give insight into the purpose of each load.

This particular write-up is in regards to our item # 50E. The Nosler Ballistic Tip was chosen for its accuracy potential. This bullet is not a deep penetrating bullet and was designed (in my opinion) for deer sized game. If you shoot a big mule deer in the shoulder at 50 yards, this bullet will likely disintegrate and not penetrate far enough to break the off shoulder and this will kill a 300 lb. animal like a large mule deer, but not an 800 lb. bull elk…….you’ll have a wounded elk on your hands. Now keep in mind that if you make that same hit with that same soft bullet at 400+ yards, due to the drop in velocity, the bullet will not rupture, will expand nicely and penetrate about twice (or more) as deep as that 50-yard shot. So my intention was to design this load for deer sized animals (In Idaho, older mule deer bucks can exceed 300 lbs.) at any distance. If you choose to shoot elk with it at close range, keep your shots double lung (no shoulders) or brain.

Below you can see what velocities my real world rifles are producing with this load.

I chose a very modern powder for this load that is temperature stable, so if you are hunting in a very cold -20° F temp. or a hot 100° F, you’ll get uniform velocities regardless of ambient temps. and thus accuracy in a wide range of conditions. I could have safely squeezed another 100+ fps from all these 7 Mag. loads, but after much testing, chose to keep pressures down and accuracy up by using these velocities. Good shooting and God bless.
