6mm Creedmoor – 115 DTAC with H4350 test with Ruger Precision Rifle

Testing today is with the 115 DTAC in 6mm Creeedmoor. We are evaluating a load using my Ruger Precision Rifle. There is velocity and group data at 150 yards. This high-BC 6mm bullet is similar to previous DTAC bullets with respect to its overall form, but has incorporated a very important design change: it has a rebated boat tail. David Tubb produces these amazing projectiles that claim a measured G1 BC of .620! We use Hornady Brass along with FED 215M primers to see if these magic bullets will stabilize in our 1:7.7 twist barrel.
