I used the 73 ELD-M last season from I think 60 to almost 400 yards, and had no drama with deer being dead (wounds were fairly dramatic at all ranges). Looks like we're about to pick up some damage tags, so hopefully I'll have a bunch more evidence in the near future.
I use the ZPacks carbon fiber stakes, similar to those linked above. Wouldn’t recommend in sandy or rocky ground, but otherwise good to go in my experience.
I volunteer to work with boys between the ages of 5 and 18, and the age they're ready for a knife caries wildly. I've seen 8 year-olds who were ready, and I've seen 15 year-olds I wouldn't trust to cut up their own food. My kids are 8 and 5; my 8 year-old uses a knife at the table, but I can't...
