Published fps

[Rerhardt]

Sorry if this has been covered, how close is the published fps of weatherby select plus ammo shooting from a 26 inch barrel?  I do not have a chronograph to get an actual fps.  257 weatherby mag, 100 grain ttsx

I've never bought Weatherby Factory ammo, but I hand load and my 300 WBY shoots 100 FPS faster than what the book says it's suppose to shoot. I'm currently working on a load for 200 grain Accubonds. With 83 grains of IMR 7828 the Nosler book says I should be shooting them around 3028 FPS. I was able to average 3150 FPS.

I also just shoot 180 grain Barnes TTSX and was getting velocity really close to 3300 FPS. The Barnes book said it would almost be 3200 FPS.

I ran some 100gr hornady interlock factory loads over the chrono. Box says 3605fps , I got an average of 3525fps. Never shot factory ttsx loads tho.
