The 425 Express - an overlooked caliber - 2 rifles added

I just acquired 2 rifles in 425 Express caliber. A custom Winchester Model 70, and an Original A-Square Hannibal.

The .425 Express cartridge was designed in 1987 by Cameron Hopkins and Whit Collins, for African hunts. Ballistically it is equally efficient as the 404 Jeffery with a shorter length. Although the cartridge was originally based on a slightly shortened .300 Winchester Magnum case, A-Square standardized the case length as the same as the 458 Win Mag. (The A-Square Company was the only Company that offered Factory ammo.) As such, making brass is an easy task. One pass in a 425 full length sizing die is all that's required.

This cartridge fits standard-length bolt actions such as the Winchester Model 70, (my new rifle) the 1917 Enfield, (my other new rifle) and Mauser 98 or other similar-length actions.

Both rifles were field tested with a moderate load, although A-Square Factory ammo was loaded to 2400 fps with a 400g bullet.

The Custom Winchester Model 70 is shown first, the A-Square second. The description above the pictures tells most of the features. However, what is most interesting is the Leupold Scope that came mounted on the Winchester. It has crosshairs that taper to the center, with a DOT at the intersection. This really offers quick target acquisition and fine shot placement.

and as always, comments are most welcome.

Good find. I have never actually seen a Leupold CPC reticle with a dot but it looks like a perfect option for use with that chambering.
 
I own one on a interarms x action. Fine round for sure but mine has horrible recoil.

Well, recoil on these 2 is relatively mild compared to some of my other rifles, like my 475 A&M, or my 700 NE double.
 
I have an extensive collection on big bores from 500 NE on down to 9.3's. My 425 really kicks, have the same rifle in 450 Watts, 375 HH, 400 HH, 458 win, 375 IMP, all are much more pleasant. My 2 cents. Still a fine round for sure.
 
It had that reputation for recoil. Is it because case size requires the use of certain powders? It needs to hit out of it's shoes? Here is a case of looking for 404 performance out of lighter loaded 416 Rem. That maintains some case options that are relatively available.

What diameter bullet does this Express cartridge use? .425”, .423”?
 
What’s the weight on the A-Square rifle?
The A-Square weighs 9 pounds 9 ounces, and the Winchester weighs 8 pounds 15 ounces. The additional weight of the A-Square, and its recoil-check stock, makes its felt recoil about 3/4 of that of the Winchester. Art Alphin really knew what he was was doing when it came to his stock design.

trperk1, I bought the Kimber Caprivi 375 back in an earlier post. You attached a target with an impressive three rounds touching 100 yards. I took the 2x10 VX5 off and put a VX6 HD Gen 2 1x6x24 Duplex Firedot on the rifle. It's definitely a shooter curious what loads you used for the group. Loving this rifle so fun to shoot. Africa 2026 Mozambique. Buff and PG. Any info appreciated.

Thanks .
