yeah the 7-2 is a sporter profile barrel. It has a deeply recessed target crown. Not sure exactly how much it weights, but shooting it off-hand isn't bad.
I have one of the 7-2 Biathlon Basic rifles too. The barrel contour isn't exactly what I would call "sporter" but not exactly what I would call "bull" either -- it has a slight taper, but it's pretty stout.
I use mine for a league that has a 7.5 pound weight limit for rifle and scope. With a Muller APV 4-14x40 scope, mine weighs 7 pounds, 7.8 ounces. Talk about cutting it close ... We shoot offhand standing, and I feel perfectly comfortable with this rifle. It doesn't feel heavy to me. Carrying it around in the field all day might be a different story. The stocks on some of the newer ones I've seen have a raised comb that mine doesn't have; I think that could potentially add some weight.
Note that the 7-2 "Basic" model does not have a lot of the features that the dedicated competition rifles have: snow cover on the muzzle, magazine carrier built into the stock, attachment points for the shoulder straps, etc.
It's my best-shooting .22 rifle out of more than a dozen that I own. The trigger is excellent. I have yet to shoot a perfect 100 target with it, but I have shot 98s and 99s.
Sadly, there's currently no US importer for these. I've seen the .22 WMRs for sale, and I think that was because some retailer jumped through the hoops to import a bunch of them. The .22 LR version is scarce as hen's teeth, and I've seen them listed on Gunbroker for $800 and up. I paid $350 for mine in 2006.
