AT3 FF-ML 20 Inch Faxon 6.5 Grendel Upper Range Result

[Jimla]

Jimla I have heard that cfe223 is very temp sensitive have you found this to be true with your testing ?

I don't have temp sensitive problems at all in Hawaii, my hunting area and range only changes +/- 10 Degrees year round. CFE223 is know to be temperature sensitive and higher velocities. If you shooting at different temps(cold and hot), I would lose 50-100fps and focus on less sensitive powers like IMR 8208 XBR and AR COMP.
