Thanks to all who replied! Because of the relatively low price I'm not as apprehensive about shooting it and potentially damaging something as expensive as a car. Groups were about 8-inches at 100 yards but low. Not sure if this was because of my lack of experience with doubles, using express sights, or the ammo, or all three or none of the above? Again, I need to reload and I guess 405 Winchester can be made into 375 2 1/2 - I've got the shooting British double rifles book packed in a box around here somewhere. I'm sure that will start me in the right direction.
