Lem, looks like you got a shooter. I have around 250 shots through my Switchback and it keeps getting better. Using 28gr W748 and 29gr CFE223 my groups with the 105 and 108 Hornadys are all under 1/2''. I am getting under 1'' with the lighter bullets using AA2230.
I am finding that pushing velocity tends to open the groups with most bullets. One exception being the 87 VMax w/29 gr AA2230 shooting .6 @2950. On cleaning my barrel after 35/45 shots I need 3 wet Hoppes #9 each followed with a couple dry and then 3 wet patches with sweets copper solvent followed again with 2 dry and finish with 91% isopropyl. Very easy barrel to clean if you are not shooting the Hornady factory loads as they are serious soot producers.
