WHen Richard came down for a visit a couple weeks ago with his close friend and my new friend Rob. I fitted one of my 257 cal Lilja test barrels onto his old Rem 700 after I gave it a good accurizing job and chambered it to the 257 STW.
After we got all the work done we did a quick load development with these same 125 gr ULD RBBT. Loaded them to right at 3500 fps with Retumbo and got her where we wanted it at 100 yards and then drove up to my long range shooting areas.
Set out some milk jugs full of water at what measured 445 yards. Plugged all the data into Exbal and it reported a hold of 10" high at this range with the zero we were using.
Told Rob to hold about 3" over the top of the milk jug and at the shot, POOOOPPP!!!! Followed her up with a second one as well.
Then we turned to some 1/2 mile rock breaking. He just had a conventional duplex reticle but once he figured the hold over, he was breaking 10" rocks easily at that range with that bullet.
I will agree, for a conventional twist 25 cal, this bullet is EXTREMELY impressive.
I will not say it hits the hardest of any 25 cal I have seen because I have played with the 156 gr ULD RBBT ALOT and that bullet has to be seen to believe its actually a 25 cal bullet landing, BUT, for conventional weight 25 cal bullets, there is really nothing close to the 125 gr ULD RBBT in a round like the STW.
Keep us posted to future results!!
