Just checking to see if anyone else came across this. I just bought a 412 AMERICAN, in .22 mag . At 50 yards , the first shot is all ways 1 inch high, then the next 4 are bang on. Is it a cold barrel thing ? The 30 grain didn't work good , but the 40 grain are munch better . Thanks all .

I have one (American in .22WMR) and have not had the issue you're writing about. Mine has always put the following shots in close proximity to the first one.

They DO take some break-in, though. Mine has always functioned well with 30s, 40s, and 50s, but it took awhile (and some ammo) to get it to SHOOTING well. Mine took about 300 rounds to come around.
It's shooting CCI 40s into 3/4" at 50 yards now, with some minor verticle stringing, and that might be me.
Keep on working with it and see what happens. If it continues to aggravate you, you might try loosening up the forearm screw, and see if that helps.
And DO keep the chamber squeaky clean, that seems to be the downfall of all the other .22WMR autoloaders prior to the 512.
I'm very happy with my 512M, and wish you the best of luck with yours. I think it will come around, but might take awhile.
