Great round! I used one for years for deer hunting. Will outrun the 7mm/08 but you have to use a LA and modern rifle
I have not loaded for one in a long time but with new powders available it would shine.

Isn’t the 7x57 a long action round?


For it is not the quarry that we truly seek, but the adventure.

Most of the modern rifles are Long action but one company is making it in a short action. My old memory just doesn't pull it up.

.

It is usually in a long action since it is in between todays short action and long action. Great old round that is well over 100 years old and with a little more case capacity it can in modern guns beat the velocities for the 7mm-08, generally it and the 7mm08 I think of as ballistic twins,,I had one for a while and it killed everything I shot it at. Have not reloaded for it in years though.

A couple of the famous people that hunted with it in the past Bell used it for elephant as the 275 Rigby same cartridge British named and Jack O'Connor's wife hunted with it a lot.

Great round- easy on the shoulder and wide range of bullet weights. One I’ve had a long time is a Ruger 77 I bought new in 1978 for 195$. Spent a lot of time working with it and ended up with 140 grain Nosler Partitions and 4064 powder. I also have a #1 that I picked up last year that I’m waiting for a little cooler weather and I’m going to try 175 grain round nose bullets in it.
Can’t go wrong with a 7x57.

175 round nose is a traditional heavy weight in the 7X57, if memory serves right it was also a 175gr FMJ that was loaded as the military round in it and there was a soft point of same shape and basic loading.

I had a 7mm Mauser barrel for my Encore from the TC custom shop. It was 24". It shot very well. I had it chopped down to 15" and used it as a pistol barrel for a few years and then sold it on.

I am now in the process of finishing up a 7mm Mauser built on a Turk Mauser action. The barreled action and bottom metal is at Cerakote right now. As soon as it comes back, it will be bedded into a Boyd's Prairie Hunter laminate stock and have a Burris Fullfield E1 3-9X with a 4A reticle. Should be a great deer rifle when it is done.

A good load for me was 45.0 grains of Rx-17 under a 140 grain Nosler BT.

Published max loads, via Hodgdon, temp stable powders.

7mm-08, H-Varget, 162 gr, 41.0 gr 2644 fps (that's slower than what a 24" barrel will do in real life)

7X57, H-Varget 37.5 gr, 2404 fps (bet that's slower too)

284 Win, H-4350, 53.5C gr, 2822 fps (still slower than real life)

Isn’t the 7x57 load data mostly watered down due to old design/construction of firearms much like the 45 colt?

I think most data for 7x57 will be well below max pressures for 7/08 so you just have to work up. Just know 7x57 has 3- 4gr more capacity than the 7/08 so it can hang no problem.

In my experience, that is the case. Also, in my experience, if you follow good loading practices, and diligently look for pressure signs, you can load up until you are not comfortable anymore, which will most likely get you a bit more than published max loads with the 7X57.

For years our local hardware store had one of those on the shelf. I admired it every time I went in. It seemed like the perfect central Texas WT rifle and I wish I had bought it. We were poor though.

KM "Karamojo" Bell of African Elephant harvesting fame is supposed to have used mil surp 175 gr FMJ's most of the time, and taken his kill shots from about 7 yards in order to hit the small "portal" in the Elephants skull structure that allowed an unobstructed brain shot.

I've been very periodically shooting a limited run USRAC M70 Fwt 7x57, with an even smaller production # of rifles equipped with factory iron sights ( rear height adjustable folding leaf & the original front hood). I started not to shoot this "collector kinda rifle" at all, and have not yet reloaded for it or taken a shot on game with it, but with inexpensive import ammo in 140gr's, I find the recoil to be not as sharp as a Fwt 308 or 270, but is sharper than the USRAC 257 Rbt's I hunted exclusivly with for a long time in the '70's until the rifleing was almost gone. Finally quit using the Rbt's when it almost got me eat up by a wounded hog that had taken 3 body hits until at 30-40 feet during the final face to face charge I "airconditioned" his brain pan while trying to dig the wounded critter out of briar patch so thick I could not stand up,.using Remmy 117gr RN bullets that was all that was availible in factory ammo at the time. Switiched back to a Ruger 77 270 for everything and cured that problem.

My longest game shot was on a Pronhorn in Wyoming however with that M70 Rbt's at 444 yards, not quite offhand, as I was leaning into the fender of the guides Bronco with my thighs. & using the rifles preferred ammo of Winchester "White Box Silvertips" the original silver aluminum tipped PSP's, that would give me 5 holes off the bench avging about 1/2 to 3/4's of an inch groups when the rifle's barrel was still good. Used to regularly win $5 bets by "writing my initials" on the back of a standard sized business card at 100 yards at the old Winchester Range in ?Dallas off Luna Rd.

I suspect this 7x57 can get close to that accuracy with reloads as it's trigger and safety & ? else has been lovingly smoothed and lightly tuned & even with the almost junk Serbian stuff can give me 3 shot's touching when my shoulder will allow it. Probably gonna try to find a factory takeoff stock and preserve the USRAC factory stock if I put it in the rotation....or mebbe not if the new to me T3 Swede Hunter & the best wood I've seen on a Hunter is as good as the pics, I just traded for & have not received yet, for will shoot as well as I expect. Still need a wet weather hunting rilfe though.

Most of the modern rifles are Long action but one company is making it in a short action. My old memory just doesn't pull it up.

I don't remember a problem with the 7mm Mauser but the Remington 722 created problems with the .257 Roberts.

If you google terminal ballistics 7x57 there is a really good write up on the cartridge. I don't see any reason in trying to hotrod it. Shooting 140-150 gr sp bullets at 7x57 velocities you will be surpised at how well it kills deer sized critters while being easy on the shoulder and a pleasure to shoot. That is why it shines and has a following.

^^This

And it is the case with most cartridges. Lawyers got involved, and neuter many cartridges. So of us begin just under book max, and work up from there. Doing this in July, and August is beneficial. I have safely gone pretty far above published max, and I have also had occasions where I had to stop climbing, because I saw the early warning signs of pressure. Shoot, lift the handle, eject the brass into my hand, and inspect the case, EVERY TIME.
