I borrowed a factory stock Tikka from a Great Buddy who let me shot it for a few matches. I also borrowed my dads CZ 457 Varmit, shot it in a few matches. The Tikka shot a little better for me, no knocks on the CZ, but the Tikka was a little more accurate, and liked all ammo I fed it. So my goal was to buy a Tikka.
I saw a fair number of Ruger RPR being run at the matches, I paid a great deal of attention to them because it was on my checkout, and possible buy list also. I noticed a couple of things, 1) if they were shooting a factory gun the accuracy was just not the same accuracy level of the Tikka and CZ, it wasn't bad, just a hair larger groupings.
2) if the RPR had been modified to shot Open Class it was very finicky, on extracting and ejecting, plus 3) if a 25 round magazine was used, if the magazine touched anything during the feeding or working of the bolt it jammed up big time. 4) RPR were also magazine sensitive with a few 10 rounders too.
I ending up getting a used Sako Quad, I could not find a Tikka at the time, all of the LGS were out. But I am very happy with my Sako Quad, I shoot in Open division now.
