Thought about two charges, and the pros-cons. I am used to double triggers, so the practical use of individual barrels ain't a stretch. May be too much hassle, making two horn measures for each barrel.
I believe the only one barrel thing applies to ML elk and deer. So if I wanted to ba'r hunt with both charged, I think I could.
As far as distance, true, I do hope to shoot at archery ranges. Always try to no matter the gun, if I can. That'd just me. Buuuut elk are where you see them. No fair opportunity shall be wasted. Thanks Jimmy.
