I purchased the Professional in 280AI a couple of months ago as well... the rifle is currently on its second vacation to PA. They didn't fix the problem the first go round. Thing still shot like crap. Had some 3 round groups where I could stack the first 2 and the 3rd would land 3" off the mark. Other groups where rounds would land in no particular pattern into an awful 4-5" group. Not sure what's going on with my rifle, but let's just say I'm not confident the problem is going to be addressed this trip either. This will be it's last trip to PA. If it does not shoot I will take it to one of the many competent smith's in this area to have it bedded properly and, if necessary, rebarreled. Seriously regretting this purchase. How's that saying go? If it sounds too good to be true, it probably is.
