Finally got mine out yesterday(.270)---it behaved much like my old A-bolt .270---it didn't like 130's----150's tightened up the groups a bit---140's make it a dang tack driver-----my final group of the day with a fully cooled barrel was 4 shots(did 4 shot groups because thats what the magazine holds) all touching in a nice little clover leaf.
Then proceded to unload the 130 and 150 gn rounds at the 200yd metal plates to have empty cases to reload more 140's.
Its nice when it all comes together and you have a good shooting gun. I'd be looking at getting another one if the price wasn't so high.
