I have the real thing and will share my experiences and some load data.
I started with a factory barrel (18.5 in in length).
Tried 140gr bullets,velocity was under 2800 ft/sec.
Had the barrel changed to 20'' and picked up around 75 ft/sec Still a little slow
for what I wanted.
Switched to 120gr Ballistic Tips and that did the trick.
Velocity increased to 3010 ft/sec with 49.5 grs H-414 and deer fell where they
This ended up being one of my favorite rifles.
The barrel is a 20''#7 taper shilen select match on a model 7 action and a AI
Best group to date .053 5 shot @ 100yrds.
A friend of mine has one with a 22'' barrel and only gets 25 to 30 ft/sec more
so it appears 20'' to 22'' of barrel is optimum.
With the short action and a 20'' barrel this is a very handy (short) rifle and a
very good running deer/hog rifle .
I have taken game over 500yrds with it and would not be afraid to shoot targets
to 600 yards with this combo.
For longer distance I would increase bullet weight to the 150gr bullets.
As for the 25/06 it would need a long action and 24'' to 26'' barrel with no
improvement in velocity with a 120gr bullet (About The largest bullet in .257).
