ITEM 50B 

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, as 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 # 50B, which utilizes the excellent Barnes 160gr. TSX bullet. This is my personal favorite elk load for the 7MM Remington Mag. This bullet will penetrate plenty deep for killing elk, even with raking shot angles. Because of its all-copper construction, this bullet will penetrate right along with the heavier famed Nosler 175gr. Partition 7MM bullet, but gives the advantage of less recoil and faster velocity. 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 the smaller big game, which has never bothered me in the least. Assuming your personal rifle shoots this load well, it would be the load I’d use if my main need was killing elk with a 7MM Remington Mag.

Note the below velocities taken from my personal test rifles.

To further educate shooters, I’m pointing out how individual rifles can be………….You’ll note that my 24 inch Remington model 700 had a very low (relatively) velocity with this bullet when compared to my other 23-inch and 24-inch barreled rifles, not only that but extreme velocity spreads went from the normal 20-30 fps to around 110 fps. Why? I don’t know. Barrel internals are unknown, but something about that bullet in that rifle does not work well, which I know seems strange because that rifle shoots other bullets exceedingly well and consistently. Never mind that I have used this 160gr. TSX bullet with great success in other rifles and have even killed bull elk with it. I hope pointing out some of these anomalies helps folks understand just how much we do not understand about internal ballistics……when a knowledgeable shooter tells you that rifles are all individual and just because one rifle does something, does not mean another rifle will, please listen to them. This may be a good time to ask you to read these links.
