When Hornady and Ruger collaborated in 2007 to create the .375 Ruger cartridge, they also in future-sight, perhaps knowingly, or not, modernized many yet-to-be named magnum calibers such as the new PRC’s. 

The .375 Ruger cartridge has no belt, no taper, larger case capacity, and a larger shoulder with which to set headspace than the .375 Holland and Holland Magnum. 

I remember reading an article by Jon Sundra in 2011 below about future 7mm, .300 and other calibers that could come from this .375 Ruger collaboration.

Did you know that the 7mm PRC and .300 PRC cartridges are children of the .375 Ruger cartridge?

And likely more will come. 

Will they replace magnums? Time will tell.

For nearly a century, many commercial magnum calibers had a belt to set headspace because they were based upon their parent cartridge case, the famed .375 Holland and Holland Magnum created in 1912.

For decades, the H&H Magnum case availability made it easy for industry to reform the case for smaller diameter “magnum” calibers like the famed 7mm Remington Magnum.

I own the .375 Ruger and love it. But it is a magnum cartridge, without saying so, perhaps like the 416 Rigby. I still like the “Magnum” moniker however. 

But the .375 H&H Magnum cartridge will likely not go away and will not for many decades to come. There are far more .375 H&H Magnum rifles in Africa and world-wide today, thus the brass case will remain in mainstream manufacture for many decades.

And the .375 H&H Magnum still has a mystique-like following in Europe and Africa as a dangerous game round up to and including elephant.

So why create a beltless “magnum” case and drop the magnum moniker?

The .375 Ruger’s brass case seen above, removed the belt, case taper and gave a better shoulder in which to set headspace.

Is that enough, to eventually replace the .375 H&H Magnum case?

Replacing the 7mm Rem Mag and 300 Winchester Magnum whose parent case in the .375 Holland and Holland Magnum will be daunting as the belt does not bother me for head space.

Accuracy and energy in my Browning X-Bolt Speed 7mm Remington Magnum, when hand loaded with 175 g bullets, achieves the same energy as the 7mm PRC factory loaded cartridge but the PRC may edge out the 7mm Mag for long range target accuracy and use heavier bullets.

I shoot sub-moa with my 7 magnum.

As a hunter, that is more accuracy than I need. And if I want a heavier hunting bullet I would go to a 30 caliber.

I, for one, like the manly term “Magnum”. And I hand load the 7mm Remington Magnum with great success and accuracy for hunting big game. 

Target shooters will likely migrate to the 7mmPRC and 300PRC  for very long range target shooting but in very heavy rifles to reduce recoil. 

The hunting community will perhaps move much slower as we do love our 7mm Rem Mag’s for long range hunting accuracy and delivered energy.

And case components and rifles for the 7mm and 300 win magnums are on the shelves world-wide right now. Not next year or so. I am older and can’t wait my friends. 

In five years more PRC rifles and components may change that dynamic. We shall see.

In the meantime, I am happy with my 7mm magnum rifle for hunting all North American big game species. 

Good Shooting

It’s all a matter of time, patience and some cash for me to get back outside to my Outdoor Life hunting, fishing, boating and camping. I began my spring with pulling my 2007 Key West boat and trailer out of storage with one of the brake pads frozen.

So much for chasing early striped bass. The fix included ordering pads and then having them installed and bleeding the air out of the trailer lines. It wasn’t cheap. But then it was windy and rainy which makes striper fishing crappy. Rain, rain go away as the saying goes. 

I got the boat home and cranked my brand new 200 hp Yamaha over and it purred in my driveway like a kitten. Nice! I was running a checklist before launch. I grabbed the hydraulic steering wheel and turned it to center the outboard but the helm wheel just spun in circles. Must have air in the hydraulic lines or something. Back to the shop.

A new helm and purged lines later, I was back in business. It is just money, right?

Next, the trailer, a bunk type needed TLC so I decided while in the shop to do repairs on it and will sell the trailer for a new roller type and protect my sizeable investment in the boat. Boat stands for; (Break Out Another Thousand $).

This is my third power boat and true to form, it is costly but you can’t trade its ocean and lake benefits of freedom on the water. Todays fiberglass, well equipped boats of my size can cost more than twice what I invested so I should take heart. 

And soon the sun will shine and the fish will bite once again.

Good Fishing and Boating and Sunshine!

The Browning X-Bolt Speed 7mm Rem Mag 26 inch 9.5 twist barrel I have tested this past three months with a new Timney trigger (set at 3 lbs), simply put a wide smile on my face today. 

Some shooters say 7mm Rem Mag in 9.5 twist is said to rarely achieve 175g spitzers at 3000fps and MOA accuracy. This may be true for some, but not here.

I am here to tell you that I have achieved hand-loaded sub-MOA results with Nosler 175g ABLR and other bullet manufacturers to 3000 fps.

Using Alliant RL 22 or Vihtavuori N560 Smokeless Gun Powder have both pushed Nosler 175 ABLR to 3000 fps while achieving sub-MOA 3 shot 100 yd accuracy. . Standard Deviation hovers around 10 fps. I am using Norma Cases and CCI or Winchester Mag primers.

I have achieved the bench rest group below three times in a row today. It’s no fluke!

I attribute my success with attention to handloading detail, a great Browning rifle, a Leupold scope, a Timney Trigger, Nosler bullets and world class powders. Note: 7mm Rem Mag ammo is on the shelf across the world for hunters.

Good Shooting!

I ran into a friend who shot a doe with spitzer type muzzleloader bullet. The deer ran hundreds of yards before dropping. And he recovered the bullet, which never mushroomed to deliver killing energy.

I advocate for semi-spitzers with rounded nose, round/flat nose or hollow point bullets for muzzleloaders that deliver sufficient energy to open/ mushroom the bullet. 

Do your homework and read up.

Avoid spitzer styles that are difficult to open and mushroom.

Most shots are taken at 40 to 60 yards and do not need sharply pointed bullets. 

You will be glad you changed bullets. I like a 300 grain semi-spitzer/hollow point for my 50 cal.  and at least 100 grains of pyrodex. 

Some examples of better mushrooming bullets.

Now is the time to shop!

I avoid sharp sleek pointed bullets that are not designed to readily expand. 

Good Shooting!
