I'm Gregg and I live in Tucson Az. My favorite thing to do is shoot across canyons down here in the Santa Rita Mountains at rocks. Yup, thats rite-rocks. I love hearing that bullet scream across there and smack that durned ole rock over there and make gravel fly ! Course, the smaller the rock, the better the challenge. I like to hunt too, tho I have not done any of that in 30 yrs or so. I found this web site trying to research 338-378 weatherby ballistics and custom rifles
. Some time ago I acquired a Ruger No 1 in a 416 Rem Mag, and I shot it quite a bit, loading my own ammo, and the cartridge just never did it for me. Frankly, IMO, at the distances I like to shoot from, it is a genuine TURD. So I got to thinking , maybe a hot rod 338. At that time, 338 Lapua was all the rage, and I looked at it close, but found the $125 for a box of 20 brass only a little distasteful. Then I remebered the 338-378 Weatherby. Not only is it faster, but my local gun store keeps a small inventory of this brass in stock, at 1/2 the price, I might add ! So, in my infinite wisdom, and realizing that I of course knew everything ( insert wise smile here ) I ordered a BEAUTIFUL Lilja barrel in the same taper as the 416 Rem Mag. Now, 2yrs later, I am getting ready to mate the two pieces together, and lo and behold, the No 1 has 1" thread shank...and it seems that this gives some folks the blues when talking about that massive Weatherby being chambered thru it. Does anyone here have any input for me ?
