My my complaint about Steyrs is there consistency. Mines is best on the chrono with express and luckily it shoots good with them. With exacts from the tin 25fps was the norm and at 55 yards that was no good to me.
Mine is pretty good 40 shot string 13fps spread on average the best ever being a 9fps spread. A normal 10 shot string is 9-10fps spread and the best is about 4fps. Once it's running good and you understand what effect the cold has on it and get a barrel cleaning regime in place it's pretty straight forward..... I hope.
