If comparing factory rifles then the nod would go to the Savage:
Accutrigger can be user adjusted to around 2lbs with a crisp pull and little to no overtravel (some models are down to 6oz). Rem promark cannot AND they are having some serious grief with safety at this time. Not sure how exaggerated this may be but the lawyers are smelling blood so this will likely get very ugly.
The rem can easily have an aftermarket trigger swapped in. Timney, Jewell and Shilen are wonderful additions but that adds costs.
The center feed det mag that is offered with the Savagea is wonderful. Built like a tank, smooth feeding and allows a cartridge almost 3" long. The Rem det mag is not so slick and most come with a hinged floorplate. The mags are also short internally which will limit bullet options and cartridge set up.
Many will put in an aftermarket bottom metal using AI type mags if they want a det mag. When installed properly, these run very well BUT that is a substantial cost both in parts and installation.
Accuracy is a toss up in factory form but I have owned, shot and seen others who have shot some really accurate Savages. Sub MOA with many around the 1/2 min mark is being reported by a large audience around the world. Sales for the Savages have skyrocketed due in large part to the likelihood of fantastic out of the box accuracy.
Rems have not seen to fare as well recently. I have owned several Rem from the 80 and early 90's production and these were nice. One of those that should have never been sold was a Classic in 222Rem. Shot fantastic, looked great, handled wonderfully, old style trigger group that could be tuned to be a gem.
For me, this was the pinnacle of the Rem 700 BDL.
Recent samples of SPS have not really impressed with with their appearance and feel. The new factory trigger is designed by a lawyer and Rem will likely be hiring a raft of them now.
If you decide you want to change parts, the Savage is a tinkerers dream. The Rem needs gunsmith intervention unless you have the tools and machines to do the work.
For max precision, the Rem should undergo the review and touch of a quality smith to make all the mating surfaces true. Many seeking top tier performance will also modify or replace the bolt to ensure true lock up.
By the time a Rem 700 is worked over, you are within a whisker of cost to a true custom action.
For me, I have been shooting competitively with my Stevens and Savage actions basically out of the factory box with only the addition of a quality match barrel prefit and chambered. Again, savings is massive.
If precision involves the performance typically of F class rifles, I am very happy with what the Savage/Stevens platform provides me.
There is no doubt Rems work and have for nearly/over 50yrs. BUT you better be prepared for spending anywhere from 2 to 4 times the cost vs a comparable Savage build.
If the Vbull match was any indication, I would say the prevalance of Savage rifles on the line has grown tremendously. I did a rough estimate and it looked like 1/3 of the rifles were Savage in either factory formed or the action the basis of a precision build.
Times they be a changing, and many shooters are getting alot of gun from the Savage line up.
There were quite a few Sightrons at this match too
