All that said, powder being increasingly expensive, if you want it all, every lick of distance, and have money to burn, the 7mm wins but by very little except for and grains where the 7mm has an edge for bigger game like Moose and better sectional density. But if you were going to hunt larger game regularly, the 7mm is not the caliber of choice.
Now we are talking about how to handle recoil in a serious way too. In my case I skipped the lesser 30 caliber and went for the. Currently my 2 gun battery is the. Making both guns easy to shoot. If you are strictly a deer hunter then the. Reloading brass from the to. From a practical cost effective application deer hunting standpoint the. The Nosler load data site gave me something to think about. Nosler makes its classic Partition and high tech AccuBond Long Range bullets in the grain, 7mm size.
The SD of these bullets is. Nosler lists 7mm Rem. The highest MV of all loads and most accurate load tested used Downrange, the MPBR would be yards, with ft. The far zero would be yards. I am impressed! In summary, the. Magnum, using bullets on the heavy side for their respective bore sizes, are potent against Class 3 game. I would not advocate going after the biggest and baddest Class 3 animals with grain bullets in the. There are three other topics I want to briefly discuss.
These are using far zero as a shooting distance limitation guide, recoil of the selected cartridge loads and reloading considerations. I am not buying into the current fad that promotes extremely long range hunting shots. Simply put, I feel that this is irresponsible hunting behavior. This gives me a margin of error in case I underestimate shooting distance in the field.
To illustrate, assume I hunt with a 7mm Remington rifle, using the grain load featured in this article. If I sight in the rifle for the MPBR of yards, but limit my hunting shots to the FZ of yards, then I have a 45 yard cushion in case I underestimate the range to my target.
Put another way, suppose that I have a shot opportunity at a deer that I visually estimate to be about yards away. If I execute the shot properly, I will still get a vital zone hit even if I have underestimated the range by some 50 yards, since the bullet trajectory will still be within the MPBR of yards.
Altogether, the five cartridges and seven loads featured in this article have an average MPBR of yards and an average FZ of yards. This means that the average range underestimation cushion is 40 yards. In my world, yards is a long hunting shot and having a range underestimation cushion of 40 yards is both a comfort and a confidence builder.
Recoil is the price to be paid for the high performance of the hotter cartridges and loads I have covered. To quantify and compare the recoil of these loads, I assumed a uniform field-ready rifle weight of 8. I did not have information on the powder charge of each factory load, so I consulted a couple of reloading data manuals to find powder charges that would drive bullets of given weights at velocities very close to the factory load velocities.
Here is a tally of the results when I entered the relevant data into a recoil calculation program. The results were pretty much as I expected. The most startling result is that the. This cartridge burns a lot of powder to get its high velocity and flat trajectory.
Everything has a cost. The 7mm has a very mild recoil, the. All five cartridges are eminently reloadable. The number of powders that work well with each cartridge has never been larger and the selection of. I checked a couple of my go-to reloading components websites and the only yellow flag I found was that there are currently only four brands of.
Brand options and prices of brass for the other four cartridges are better. Three of these cartridges already have complimentary labels. Chuck Hawks has called the. It seems to me that these five cartridges, among them, offer pretty much anything a hunter could wish for in the. Note: Full length articles about all of the cartridges mentioned in this article can be found on the Rifle Cartridges index page.
Overview of rifle and factory ammunition availability Here are some indicative data that give a sense of the availability of rifles and ammo options in each of these cartridges. Performance of selected loads in each cartridge To evaluate performance of the cartridges, I chose a single "workhorse" Federal Premium brand commercial load in each non-magnum cartridge.
Nosler Ballistic Tip, MV f. Trophy Bonded Tip, MV f. Nosler Partition, MV f. FZ yds. Mag, gr. Other considerations There are three other topics I want to briefly discuss. Both are very close on cartridge best-seller lists , usually lurking around the No. The real difference, if there is such a thing, is that the 7mm Rem Mag is not truly a magnum, and that the. The cartridge had just enough bullet weight to take on any North American big game except the big bears. It had enough velocity to make hitting easy at what was then considered long range.
There was a grain load that did around 3, fps, and a grain bullet that made 2, with a strong following wind. And it had very little recoil. The 7mm Remington Magnum debuted in , chambered in the brand-new Model rifle.
The cartridge was loaded with grain bullets at fps and grain slugs at These are real-world figures from my own chronographing. The round was a major, and immediate, success. One of the factors that drove the 7mm Remington Mag was undoubtedly the excellence of the Model Those rifles would shoot.
In fact, the first sub-MOA group I ever saw from a big-game rifle was shot by a gun writer named Bob Zwirz with a in 7 mag. The rest of the load was CCI primers and 68 grains of the old Hodgdon powder. This was in , and it made such an impression on me that I remember the load today, when I often have trouble remembering who I am. Zwirz cut out the group and kept it in his wallet. When he showed it to people they became hushed, and a few wept openly.
Another factor that helped the 7mm Rem Mag was the fact that in , hardly anyone had a chronograph, and if you did, using it was a major pain. After all, it kicked more and made more noise than a. Herein lies something of a mystery. When the Remington magnum was developed, it was by no means the first such round in. Les was a Wyoming gun nut, and outfitter, and I think they sent him an experimental rifle in the new caliber, and he loved it, and so they went with it.
