There is no simple answer, let me try and cover it quickly and as simply as possible.
First off I do not know this pellet but it is VERY heavy for a .177. Actually it's heavy for a .22 as well.
In an air rifle the GUN provides the power, conventionally up to 12ft lb, whatever pellet you put in will effect this power to a small extent as pellet weight, shape, BC all have an effect on the efficiency of the pellet to carry energy!!
In a cartridge rifle/shotgun the cartridge itself provides the power not the gun, and there can be some VERY wide differences in power in the same rifle.
