Re: what should i expect..257 Wby mag
I have a 257 Wby Mag too. It's a stainless Vanguard Classic.
Expect to have to tune the trigger and lap the lugs. I also bedded the action and floated the barrel but it already shot well so it didn't make much difference.
My load, which always shoots around 3/4 inch, is:
100gr TSXs, 73.0gr RL22, 3725fps, COL 3.18, CCI LM primers
Recomended COL is 3.25. Mine is more accurate seated back from that. In this gun, with a Weatherby throat, that's a long f'in jump. But it is what it is.
I'm pretty happy with the volocity at 3725fps. I admit it's a hot load, but I get no high pressure signs unless it's a real hot day. RL22 is a very temp-sensitive powder.
Long Time Long Ranger is getting in the low 38XX fps in his .257. I'm not sure what his load is though. Maybe he'll chime in and give out.
You are going to be so happy with this caliber. I call it my .257Laserbee.
