Hi all,

It appears I'm the second to register on the forum. I hope this is going to be an active forum with much learning, new ideas, and making new friends.

One of my main interests are wildcats. I've been trying to find info on the quarter bore doing 4000 fps or close to it anyway. Saw an article on a .257/.300 Winchester Magnum and found it interesting. I've thought about making a .257/7mm Remington Magnum. I think it would produce the same type of results and the brass would be cheaper and easier to reform as it is closer to the .257 bore.

Saw an article on a ..257 WSM and .25 SUAM both produced the same type of results with Weatherby .257 type velocities. Impresive antelope medicine for sure! 8)

Looking forward to hearing from everyone as this forum gets kicked off.

If the moderator/founder doesn't mind...I will post about this forum on some other shooting forums I belong to...I'll wait for your reply before I do though.

It will be hard for these forums to gain a nitch but I would welcome any new visitors and topics! As for the cartridge you are describing, I have some info on the 257/300 Win Mag and I will need to dig through my files as at one point I was going to add quarter-bore cartridge pages on the website but I have always been too busy. If anybody would like to take a stab at putting overviews for any of the .257 cartridges I will be honored to host your review and post your full credit for doing the write-uo!

Now, as for the 257-7mm Rem Mag wildcat. It would be a rocket of a rifle but it will also need a really long barrel as I am not sure you can get away with even a 26-inch barrel with many powders in a case that big pusing a 257 slug. Then again, all fun project come with some costs and it would be a fairly easy wildcat for most gunsmiths!

Thanks for joining me here in the forum!

Hi folks, I just joined cause I'm kind of a quarterbore nut myself. I shoot,
among other things a .257 WBY. I was given this rifle by my Dad over 40
years ago and just had to have it rebarrelled. I think the 25 cal. rifles do
a marvelous job on game, especially with the newer premium bullets available nowadays. Sure hope Hornady makes a 117 gr. Interbond! As to .25 cal wildcats, there is one around here called the .257 STW. It is ,of
course based on the 8mmMag. case. I suppose that this is probably the practical limit for .25 caliber. As for 4000 fps, I have achieved that with 75 grain bullets. It's a great coyote load and with Barnes X bullets, it does in whitetails VERY efficiently. I am still breaking in the new barrel on my .257, but it is shooting 5 shots nicely within .5 inches already. This rifle has never failed to impress me as to dispatching game, even elk. My daughter killed her first elk with it. Enough for now, catch you all later.

The Winchester Super Short Mag 257 is a duplicate of the 25-06. I would like to see a 257 Win. Short Mag.from the cases they use for the 270 W SM. It could be close to the 257 Weatherby but with longer case life.

Tuck, I hear ya ! But I have solved that problem. Innovative Technologies make a belted magnum case resizer that resizes that portion of the belted magnum case just foward of the belt. Even full length resizing dies couldn't do that. Now I can have just as long a case life as non-belted magnums. The really nice thing too is that the die works for all belted magnums (with only a couple of exceptions). Have a good one.

I was wondering if anyone has heard of this one? From what I have heard it was made in findland on a seko action but I don't know much about it. I just want a short mag in .25 cal.

Here is a 257 mag that was cooked up down the road from me.

Wow... I would love to see what that would do to a small furry groundhog... Then again, my 243 with 55-gr Nosler BTs are moving at just over 4000-fps and there ain't a while lot left after one of those explode

I am working towards putting a 257 STW together for my attempt at 4000 fps.

I have a Savage 7MM STW that I plan on making it a switch barrel gun. I will obtain a Douglas or Pac-Nor barrel chambered and threaded with lock nut, probably about 30" long and in a heavy varmint taper. With a 100 grn Berger or similar bullet I should be able to doe this.

I am iputting my gun fund back together from the 7mm STW purchase and should be able to start this project first of 08.

Hey Tuck, on your comment about the 25wssm...did you mean case life is shorter with these cases? I heard that once before in Precision Shooting magazine just a couple months ago and was wondering if anyone else had that problem. I have a 25, but have only loaded the cases a couple times so I don't know how many reloads to expect.
