i figured an adjustible hha would be usefull for many of my toys
ranging the havoc, shooting a 22lr to 400 yards, making me buy a crossbow
on a crossbow it can handle you out to 70 and you would not fire a bolt further than their anyway
on a sr1 i could care less about a 20 yard shot, on a crossbow thats medium range.
i work the hha backwards and get it on paper at 100 and see where it cranks back to.
also if you mount the scope further foreward, i believe you increase the drop.
i could put it on a 20 degree scope mount.
