Thanks CZman! I'll give them a call.
I've had the stock off mine to adjust the trigger to my liking and to check the adjustment of things. This .270 is a really good gun, basically, but the shifting points of impact have really affected my confidence in the gun and I either need to get rid of it or fix it.
Do you happen to know of a good replacement base and rings, preferably aluminum rings, for the 550?
If I can cut a pound off it's weight, I'll undoubtedly keep it.
Thanks again, and good shooting to you!
