So a couple of months ago I bought a new bow. When I purchased it, the wrong draw module was put in. It was a 27.5, I didn't realize it at first and shot it for a few weeks before I noticed. I was shooting it really good, I had tight groups, but I was only shooting to 20 yards. After I figured it out I took it back and asked about it, the shop put in the correct Mod 26.5, (by the charts anyway). Since then, my groups have not been as good, I have had it looked at by another shop, and they agree I should have a 26.5 draw length and I have the correct arrows and the bow is in tune per the dealer as well. Do you think it will just take time getting used to the shorter draw? Should I consider, putting in a 27 Mod, and shooting it for awhile?
