What is a 257 Condor? How are the cases formed? Any help would be appreciated....

I believe that it was a .257" built on a 2.5" standard magnum case (in other words, a .257 Weatherby without the double radius shoulder). When I get home tonight, I'll look it up in Ackley's book.

Lee,
Thanks for responding. Now I will muddy the waters even further: Can you safely shoot 257 Weatherby ammo from a 257 Condor?? I saw a Ruger #1 in 257 Condor but I do not reload. Thanks for any and all input!

Tim...I wouldn't recommend it. I'll have to see about the total case length of the Condor, but it seems to me that it was different from that of the Weatherby. I also think that the shoulder position and overall taper are different as well.

Also, the Condor was one of the 'fast twist' cartridges. If I remember correctly it had a 1 in 7" twist to stabilize handmade 150-160gr bullets. Many over the counter bullets with cup jackets cannot take the torque and come apart. 75-85gr bullets are just vapor trails. Also had a heck of a problem with throat erosion. Don't remember the type of barrel steel, but first signs showed up in the first 100 rounds. Mostly experimental very specialized piece.

Blackhawk is correct. The 257Condor was designed around a 160gr. bullet and a 1-7 twist. I believe the designer was a gunsmith named Harold McFarland.

Who makes 150 or 160 gr bullets for a 25 caliber?

Barnes ( original factory ) had make very heavy bullet in some caliber some year ago

good shooting

Even the jacket on the Barnes will likely be too thin. Condor bullets were hand swaged with heavier tempered jackets. Barnes originals are usually .025 and untempered.
