Not a gunwriter, but I have a NULA 300 Win Mag that was built for me in late 2001.
It is a push feed, and has never failed me in feeding.
It is indeed light. Mine is about 7lbs. with scope, ammo, sling. It's awesome to carry!
Mine does kick sharply, but not so much as to compromise my ability to get under 1" at 100 yards.
When sighting in, make sure you let the thin barrel cool thoroughly between shots. I bring 2-3 guns as a matter of course when I sight in so I can let all my barrels cool between shots.
As for customer service, with NULA it's excellent. Whenever I have had questions, I called and got to talk directly to Melvin Forbes, not some clueless desk jockey who has never even shot a gun before. Mr. Forbes stands behind his rifles 100%.
I'm no rifle expert, but I do know that you could do a lot worse than to go with NULA.
