I bought a Remington mod 700 SS in 300 weatherby, everything works great when I use Federal ammo for it (180gr Partitions). I picked up 4 boxes of weatherby 180 gr X Bullets and fired 1 shot at the range, the shot hit were I aimed, great I thought to myself----But thencould not open the bolt to eject the shell. The range officer came over with a metal rod and sent it down the barrel, which made the bolt open. I fired another round to see if it was that one cartridge, It happened again, and a third time. The range officer said it was caused by the Weatherby ammo, being loaded "hotter", and some guys said it was beause remington is a piece of junk. Has this happened to anyone else? & can something be done to fix this?

thanks
