I can only comment on the Ruger. Owned and shot several. Bought them b/c I could afford them. Never happy with overall accuracy until I began reloading. Then I was able to achieve acceptable hunting groups for mid range: 1" at 100.
Long story short, bbl was ruined in flood, got a new Hart bbl put on, action trued, glass bed, float bbl. Now this Ruger/Hart combo will punch several different bullets less than 1/2" with several different powders.
I've owned a Ruger 308 which defied any reputation of Ruger's inaccuracy problems. Shot as good or better than an out of the box Savage.
My current Hart bbl Ruger is a 270 and out of my 9 custom rifles
it goes to a lot of places b/c it's so accurate.
