I just recently got into long distance shooting myself and picked up a RPR in .308 to get my feet wet, so far I love the gun, still have a lot to learn, these are some of the best groups I've shot with it so far. So far I don't hand load, maybe some day I'll get into it, finding one of the guns favourite loads is also the cheapest match ammo I can get so happy with that.
I shot this at 100 yards with my factory barrel in .308 using Hornady 155 steel match
Shot this 5 shot group (1" squares) breaking in a custom .308 barrel at 100 yards same ammo.
Shot this at 885 yards same factory ammo, this is the furthest and only time I've been with it thus far, was the best of the three groups I did at that distance.
Just upgraded my 6-24 FFP PST to this ATACR 5-25 F1, have only shot at 100 yards with it so far, can't wait to try it out at distance, it's very nice and clear. Also tested some more factory match ammo at 100 that day and found a couple more loads it likes with way better ballistics according to my app vs the 155 I've been using.
