The SMK XS78 is a copy of a Crosman model 2260 sold in the USA. The SMK is sold in the UK. The Powerletts are loaded with the tips pointed in opposite directions. In other words Butt to Butt. The first powerlett faces nose in and the second one faced nose out. The loading chamber is under the barrel.

I suggest contacting an SMK dealer and asking them. See the link below
The SMK XS Super Grade 20 is a break barrel. That means you pull down on the barrel and load it through the back of the barrel after you cock it all the way open.
Seek medical attention right away.

When you say Air Rifle you are referring to a pellet rifle not a firearm. At present there are no 300 Cal air rifle being made.
Only if the scope is designed for an air rifle. Because of the recoil being different on an air rifle than a firearms rifle. Air rifle scopes are made differently than firearms scopes. A firearms scope can break it's glass mounts if it is used on an air rifle.
