A new bow brings new challenges to shooting

So a few weeks back I ordered a bow from a guy named Nate Steele of Bama Bows out of Tulsa, Oklahoma. I went big with the thought of someday going to Africa to hunt big game. I selected the most basic model because I like minimalist bows and the price was right. I asked him to make a 100 pound draw longbow and it arrived some six weeks later. I recieved the new bow two days ago and have been actively shooting it as much as I am physically able.  Yesterday I took four shots with the bow and today I took about a dozen. The physical toll this takes on the muscles is amazing. The process is like a workout with shooting, two of my favorite things. Today I have taken about 30 shots in a series of two sessions. The accuracy is nothing to brag about but I can hit a four inch circle 4 out of 6 shots at ten yards. The penetration that this setup is achieving is incredible. From 15 to 20 inches into target backers is common with the two types of arrows I am using.
