I own both Browning std and BPCR models. I also own both Ruger #1 and #3 rifles.
Neither are the greatest thing to put a scope on though with some planning both will work ok.

I like to shoot single shots with tang sights. The Rugers are pretty much a loser without a lot of expensive gunsmithing.
The tanged models of the Browning are ready to mount for tang sights.

Unlike some shooters I have fired both rifle types far more than any hunter. I shot rifles with both metallic sights and scopes.
The one modern caliber rifle is a Ruger #1S in 7mm Rem Mag. Though I used Wilson benchrest dies and techniques accuracy was never much better than 1 1/8" to 1 1/4" at 100 yards. This was using both a 2X7 Burris and a 12X Weaver.
By contrast I shot similar groups with cast bullets using a Browning BPCR IN 40-65 using a tang sight.
