[QUOTE="jebel, post: 1452004, member: 106189"] If you assume 2,850 fps (as suggested by AZshooter with RL-16), shooting an ELDx 150gr would result in an SG of 1.05 at sea level with 1:11 twist. If your twist is 1:10, the SG goes to 1.27. If it's 1:9.5, the SG is 1.41. I subscribe to the camp that you want an SG of 1.5 at sea level to reliably stabilize, but others may differ. If you took that same 1:9.5 twist rifle up to 2,500' elevation (and you truly got your 2,850 fps), your SG would go to 1.52. [/QUOTE]
