So had a jam today with the 130 Sierra Game Changers and 68 gr 2217 / H1000 shot a 25mm group (5 shots) no velocity data as there were two other users and the LabRadar was getting a bit confused.
That said, the POI was about 10mm higher than my 140 SST load at a chronographed 3050 fps, So I estimate they were cruising at 3100 ish.
Load was warm, so wouldn't go any higher than another grain.
Will load at 68 and chrony tomorrow before some long range goats and autopsies to see how these new bullets go.
Also picked up some RL33 (cheers for the jungle tip @Kiwi Greg) to try with the 140's.
