257 __________ ? name this wildcat

[jasonco]

257 Vaper.

I got a better one... 257 Chimera.

25 HLP (25 HeLP ) that wont be a beginners wildcat case to form. should be able to keep it 2.800 and fit in any action without modifications. cant wait to hear more on this case and will the hunting bullet still require the same rate of twist as the 131?

Using simple proportions from the picture the case is 0.543 bolt face and 1.87 inches long. A shortened SS or SST. Great little short action case for the long bullets.

no rebated rim it is the other .532 case and your length is real close . we must be going down the same road

257 PRO & LRH are already toys of swamplord. Imagine this bullet being launched from a 111gr norma improved case, yup he does it!

PRO is already used by another member here for his 300 NORMA case wildcats

This was my guess as well, shortened prc case with shoulder pushed back, perhaps improved shoulder angle from pic, looks to be 35-40° bunch of f'n gun nerds, get out a caliper and start reverse engineering a picture from quick-design.....yup we're guilty!

Can't measure exactly from that picture but it's the standard magnum bolt face and shorter than Rich's cases.

I like 257 Blackjack. Keep the company name up front.

25 dasher

 

[Creedmoor shooter]

257 creedmoor magnum

 

[can1010]

already built it in quick design. came up with 59.3 grains capacity and a little more tweaking could get it exact . I am thinking 32 degree on shoulder maybe to 35 to control case growth but no more than that for PRS type matches

If you want it to survive; keep Remington far, far away...
