I just bought a new browning a bolt medallion 300 wsm. whent to camp to shoot it and it wont chamber a shell i cant figure out why? I tried to call browning and cant get an answer from any one. any one no what could be the problem? i have a couple other brownings and have never had a problem with any of them

It has an external clip right?? If it does I had mine bend on the tabs just a little bit and it wouldn't let the bolt grab the bullet...just push it to the side....just a thought?

The short mags have been having problems loading and ejecting shells since they came out. Sounds like you just got one of "those" guns, take it back to the place you bought it before you try and deal directly with Browning.
