The Big Cat 1250 fire a .177 caliber pellet. If you are looking for more specific information, I would contact GAMO USE directly and ask them.
See the link below
It's usually on the side of the barrel, close to the hinge
Yes it is. It is a single shot .177 pellet rifle. It is not a BB rifle.
About 3 inches at the barrel.
a big barrel baseball bat is a bat that is at least 2 5/8th inches in diameter, these bats can only be used in jr. high or higher levels of baseball
They are both Excellent Rifles but I personally feel the Gamo has the edge on the Crosman. Both shoot lead pellets at 1000 FPS. Both will shoot the PBA pellets at 1200 FPS. The Gamo has a 38lbs cocking effort while the Crosman has a 31.5lbs cocking effort. The Crosman with scope is a little less expensive than the Gamo with scope. So it this isn't a big deal to you then I would go with the Gamo Big cat.

Calibre refers to the diameter of the barrel of a gun. Also known as the bore. It is referred to in imperial measure or metric depending on the manufacturer
Get a GR3T trigger for it. It is considered the very best trigger available for Gamo. See the link below
Take a look at the comparison chart (see the link below) I think the Gamo has a slight edge over the Black hawk.
1250 square miles.
This is like asking is Ford better than Chevy. It all really personal opinion. The Gamo cost a little more but both are rated at 1000 FPS. The XT has a wood stock the Gamo has a synthetic stock. So the choice is yours.
First of all it must be legal in the country where you live to make this modification. Second I would contact Gamo and ask them directly for the parts list.
