Hey y’all, I went out today after getting the new Athlon chrono. Got a low 7.X SD using Barnes LRX in 6.5 PRC over 17 rounds.
Both rifles are chambered in 6.5 PRC.
One is a Sako S20, 24” with an area 419 t-match brake, and the other is a Tikka T3x Superlite, chopped to 20” with a scythe-TI.
Barrels should nearly identical from the factory (same flutes, mostly same company).
Average velocities were 3024fps over 7 rounds, and 2907fps over 10 rounds, which supports the 25fps/inch rule of thumb.
The Tikka (isn’t broken in, so I expect it to speed up a little bit, and the suppressor likely sped it up just a hair.
Not sure if this post is helpful, but it’s the kind of information I look for sometimes.
