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 years age 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 dark 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 in heavy cover. 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 unsportsmanlike discussion, but that is likely because they have never done what I am about to describe 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, bad angle 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 on older bulls. 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, no problem.
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 on big game…………..
This write-up is in regards to our item # 50A, which utilizes the excellent Nosler 175gr. partition bullet. This bullet will penetrate plenty deep for killing elk, even with raking shot angles. In fact, in the days before “premium” big game bullets, Nosler was the first, with their partition bullet and while Nosler has done several upgrades of this bullet over the decades, this is the bullet that turned Remington’s 7 Mag. into an elk effective cartridge……This bullet has likely killed tens of thousands of elk since its inception. This bullet is soft enough on the nose to mushroom at very long ranges (reduced velocity) and yet due to its tapered jacket, partition and core material, it will not come apart or over expand on very close shots with super high impact velocity, even on the big should bones of a bull elk or moose. For those of you who prefer to use one load for all your big game hunting (in order to avoid re-sighting for different loads), this is a good choice as it will kill deer sized critters just fine too, but will certainly over-penetrate on smaller big game, which has never bothered me in the least.
This load has the same purpose as our Item 50B, which utilizes the Barnes TSX bullet. I chose to make two 7MM Mag. loads that duplicated each other’s purpose just in case your rifle does not like (shoot accurately) the Barnes 160 gr. TSX, perhaps it will shoot well with the 175gr. Nosler partition bullet. Keep in mind that the 160gr. TSX bullet is significantly longer than this 175gr. Nosler bullet, due to the light weight of solid copper and this high sectional density coupled with the expansion characteristics of copper, makes the lighter TSX bullet a very deep penetrator for its weight, but alas, some rifles are bound to not shoot the TSX bullet with great accuracy and the same can be true of any bullet design. So we give you options. This is a great place to read this link: HOW WILL THIS (name any) AMMO FEED AND FUNCTION IN MY “GUN”?
