This is humble stuff: it is only a cow, cheaply, on short notice (next weekend).
I jacked up my equipment to meet Natcon specs of minimum 600gr arrow and 80 ft.pd energy, screwed my bow up to 80 pd to give me 245 ft/sec to get there, had 6 arrows inserted with weight tubes and a knife maker make me 6 one-piece 2 bladed broad heads.
No salt licks, water spots or hides, which leaves walk and stalk option only. I committed myself not to exceed a 20yds shot, oblique, quartering away only.
Please keep al fingers crossed.
Lochi.

All best - throwing sticks at buff, tsk tsk . Don't get "stepped" upon, and do let us know how it went, successful or not.

some wiseguy might ask if you are taking a 45-70 for back up? But I wouldn't think of raising that issue.
