I'm going to buy the first one that comes my way, especially if it's offered in stainless steel.

The biggest buck I ever shot was with a Remington 600 in .350 and it worked every bit as well as you might think. I've owned or used three 600's in .350, had a couple of 660's and at least two Mohawks. All were in .350 or .308. I still have a Mohawk .308 and a 600 in .350.

A couple of points that may be worth considering before you lay your money down...

These are lightweight carbines, not rifles in the traditional sense. They are wonderful short to medium range hunting tools, especially well suited to heavy cover. A real consideration for hunters is the bolt action. The first shot will be right on the money but there may not be a quick second. If you are fond of autoloaders, levers or pumps a 673 may not meet your requirements. If you live in beanfield country or the wide-open west, the .350 may not be a best choice. Back east, this will be a strong performer, if you can live with a bolt gun.

I found the Mohawk to be the most likeable of the three members of the old 600 family. Just personal preference but with good reason. I also found that recoil on the .350 was way over-rated and over-reported, while recoil on a standard 600 in .308 was way under-rated. The .350 had better stocking and a good recoil pad. Add a sling and scope, perhaps a steel trigger guard if you could find one, and the .350 was no problem to shoot. A 600 series factory .308 without recoil pad or scope was flat out no fun to practice with. I suspect that anybody that had range time with a 600 in .308 wanted no part of a .350. Too bad. My son has a lightweight '06 that clearly produces more felt recoil than a .350.

The .350 cartridge performed well for me on deer. Tracking is a skill you won't be needing if the bullet is reasonably well placed. I did not use the 250 grain loads as the 200's were highly effective.

It looks like the lines for the 673 are already starting to form. I plan on being right up front. I'd hate to think that Remington might start this project up and then get cold feet, stopping production as they have done in the past.

This is going to be one great little carbine. I'm still calling it a carbine because the last I read it was going to have a 20 inch barrel. I, for one, hope that is the barrel length available in production guns.

At any rate, just an opinion based on a lot of time in the saddle with 600's.
