My son and I both scored on some tender does using our new Vortex crossbows with Bolt Cutter broadheads.
Both were shot at 20 yards, and both ran about 20 yards before going down. My son's deer ran in the open so he saw it fall, while mine ducked into heavy cover. Both were hit just behind the shoulder with the bolt passing out in the mid rib area on the other side.
My only concern is that there was almost no blood on the ground from my son's deer and I didn't see any at all from my shot. I watched the FireNock disappear right where I was aiming so I knew I hit it right, but I was dismayed at not seeing a blood trail. I was relieved at finding the deer along the deer trail that I thought it picked, but what if the shot were off a bit and the deer ran off through a maze of trails with no blood trail to follow?
Upon dressing my deer, all the blood had remained inside the cavity but with plenty of damage, not unlike what is typical from a rifle bullet.
So now I'm wondering if I should switch to the 100 grain Excalibur Mechanical broadheads? And why isn't that made in 150 grain? I take it that heavier Boltcutter is more accurate than lighter broadheads, while the Mechanical is plenty accurate in 100 grain plus there's some speed advantage, plus less wind drift.
In the past, I've read of problems with Mechanicals, but Excalibur's version looks pretty foolproof?
I just switched to 125 grn. Swhackers, and problem solved, 
see my post, (Swackers Scored ) you'l see what i mean.
