...I have a Tika 22/250 it shoots fairly good. I have tried - AA2230, H335, IMR 4064, Win 748, and H414 for powders. I am using 55 Gr Rem Sp bullets, as I don't see spending a fortune for Prairie dogs as a neccessity. Most of these loads are shooting 10 shot groups at 1 1/4". some 5 shot groups go just under an inch. Any one have any ideas on a good powder or load? For the most part it's probably good enough for them.. but a reloader always tries to get better results!! .....I read about all these great sub 1/2 minute of angle loads & I think they are full of themselves. I always said anyone can get lucky & shoot a 3 or 5 shot group tiny as heck once... and say the gun can do it all day! 10 shot groups don't lie and it takes a damn good shooter & gun to achieve those kind of results. One little wiggle and!!!
