Your 284 FPS setup would lose -4.63 inches of trajectory from 40-45 yards.

Your 306 FPS setup would lose -3.90 inches of trajectory from 40 - 45 yards.

So Basicaly you make up 3/4 of an inch with the extra 22 FPS.

It would for sure help you stay in the 10 ring on some of the larger McKenzie targets and god forbid the 8's of the smaller ones
