.257 ai

[Trickymissfit]

Did you mean wsm or wsaum? I have a 25 Bobcat ( 25 x 270 WSM } had my own reamer cut so i named it after my company. I feel its very efficient i can get 257 whby. vel. out of a short action. Have 2 of the 25x284's also very efficient chambering.

25WSM. I said to myself that this case would make a nice little 6.5 round with all that case volume. I've never been in love with the .257 WBY mag, but other folks love it.

I have a buddy whom a local gunsmith is doing one for. Only trouble i ran in to was you need a base die, i learned the hard way. But very efficient in my 25, i had 2 whbys and nice at time but with this and the 25-284 i took the scopes off of the whby.
