I apologize for my statement being misread or misinterpretedI did not intend for it to bewritten in poor taste. I truly appreciate your input DnK and very sorry if I came accross as ungrateful.

DnK you are very much correct that elk are very tough, as you experienced with your .300 WM. Of the 14 Public Land bulls I have harvested in CO and NM, only two have dropped in ther tracks (neck shots). Shots in the vitals with rifle or muzzleloader usually allow the elk to make atleast a few more tracks. My intentions are to find a combination for my crossbow that will ethically and efficiently harvest elk, without experimenting on elk. Most of what I find in regard to crossbows is geared toward whitetail whichI would assume are more fragile than elk. Luckydog may want to confirm that though.
Ranger which scope are you interested in? Are your rage the 2's or 3's?
I was thinking along the lines of Bowfisherman that the two blade might weasel in a little farther. My thinking now is more aligned with DnK and Luckydog that mechanicals won't be strong enough.

Thankyou for all of your input.
