The Benjamin 250 is one of three pistols that make up the 250 line of air guns. Here is how they break down: 250 is a .175 BB pistol 252 is a .22 caliber pellet pistol 257 is a .177 caliber pistol. The problem is finding .175 BB's today most all BB are .177 caliber. I've heard that BB are still .175 only the caliber of the barrel has moved up to .177 to accommodate pellets. I suggest you just try one.
This model was made by Daisy. Its a model 1894 and shoots standard .177 caliber BBs'
NO the Daisy Powerline 1200 is strictly a BB pistol that fires a .175 size BB not a .177 pellet
The 15XT is a BB pistol, like the name says. It is not a Pellet pistol. If you can't force is back into the BB holding slide then you might as well buy a new pistol. You will need a .177 caliber cleaning rod and use it to push the pellet back into the BB loading port
It would be worth between $65 - $75
You will need a .177 caliber cleaning rod to push the pellet back into the loading breech from the barrel.
