Sierra 130 grain Tipped Game Changer TGK for 6.5mm Creedmoor
I got two boxes of 130 grain Sierra Game Changer TGK bullets on Saturday and I put together two loads with IMR4451 Enduron powder for my Savage 12 LRP.
Temperature was between 34 and 44 degrees over a two-hour period with winds calm to 2 mph.
Shot four 5-round groups with each of 2 TGK loads using Lapua brass and CCI BR-4 primers. The 8 groups averaged 0.377

The Game Changers seem to shoot as well as the Tipped Match Kings.
Another comparison, the Hornady 143 ELD-X bullets average 0.353 with IMR4451 Enduron powder based upon 46 groups.
But this particular 12 LRP likes heavier bullets.
