I should have one of these arriving a few days. I was wondering what your likes and dislikes are. What are some of the considerations I need to take into account for bag setup for the unusual buttstock design. I have short arms and the stock will most likely be shortened. Was considering an adjustable buttplate incase i ever want to get into F-Class. Will be using a Rem 700SA chambered in 6.5x47L mostly for IBS 600yd.
