Does anybody have one of these and how do like it?

howdy
every 257 weatherby owner "has" one, with a differnt shoulder, and with good bullets, they are perfect deer rifles

Well I could never see the need for it over the Wby. Longer action required. More powder more barrel wear. Small gains in velocity. If the 257Wby won't kill it get a bigger caliber.

I built one for a customer about a year and a half ago. We did some load developement for it. The customer only wanted to shoot 100g bullets and we found the case to be far too big for that light of a bullet, and probably too big even for 120s. Lots of wierd pressure problems with not very impressive velocity for the ammount of powder burned. In my opinion it's too much of a good thing. The 257 Weatherby is a great cartridge that does work.

My friend has 1 and loves it. It is a Sako 75 action with a 27" Lilja barrel. It shoots 110 Accubonds at right around 3900, if I remember right, at just under 1" groups. I'm thinking of building 1 myself. I have also thought about a 6.5 RUM. Has anyone tried that?

The .257 Wby combination,IMO, is just about the maximum amount of overbore that the .25 caliber can support. The .257 Wby is an excellent ctg. that I am extremely fond of. Dr.C

I hope that the 110-grain bullet velocity at 3900 fps is based on poor memory. The cartridge designer listed maximum velocities in a 26" Shilen barrel with 115-grain Noslers at 3613 fps; max for 100s was 3807 fps. 3900 fps with the 110s would most likely be far too hot. The designer found that at similar pressures, the STW had a practical 200 fps increase over the Weatherby. This is a major advantage to some shooters, and not to others.
