Buy quality ammo and test it in you rifle. RPR is the same as every other rifle in that aspect
This. All the ammo recommendations that were good in 2018 are still good now……only the price and availability have changed.
Add the 185grn Juggernaut load that ReservoirDawg10 mentioned. Federal loads it in the Gold Medal line. Berger loads it, as well. Of course, you can handload it.
If you’re never going to shoot past 600yds, and don’t need to penetrate through glass and such, the 168grn match loads will do fine.
For longer distances, or enhanced penetration, the 175grn-185grn loads will work best for you.
