Doug,
Since I've not taken an elk, I'll leave your latest question for those who have, but wanted to give an "Amen" to what Mickey and John had to say. If you are new to "Primitive Archery," these are two of the voices to listen to. WIth the bows they've built and the game they've taken with them, I respect both their perspectives!
I just wanted to comment on the problem I saw several times with guys who wanted to chrono wood bows. They shot their new pride and joy, didn't see numbers that equalled or topped an Adcock ACS or Border Black ouglas, and were suddenly no longer happy with what had just previously been a prized possession!
They shoot again, now overdrawing by an inch (or maybe two), try lighter arrows, ANYTHING for a number that will STILL not reach the magic figures we sometimes hear. Sometimes, the bow is even damaged or takes a set from the abuse....
That's the worst-case scenario of chronos and wood. I know that is not what you were after or asking, but it is why I agree so strongly this the advice you got from Mickey and John!
Get to "know" your bow, learn to shoot it well, and enjoy your hunt. The number is just... a number!
Hope you have a GREAT hunt and a wonderful time with your new direction in archery! It's all so good!
