Any info on these two I can find seem to give very similar velocity with a 140g bullet. Somewhere in the area of 2800 - 3000 fps. What am I missing? I'm trying to decide one one of these for an Encore, but like I said most info I can find put these two on par with each other. I have read that the 6.5/284 is generally more accurate simply by the design of the 284 case. I will use this primarily for whitetail and mule deer. Any input will be greatly appreciated. Thanks
