Thanks for that but is there another one that applies. I'm playing around with a Burris Eliminator.

The G7 more closely applies to a HBC, if you want your drops to be accurate dont use G1 as its the standard for short flat based projectiles which of course HBC's are not. If your just wanting to get on paper it probably doesnt matter all that much.
