Amazing how a diplomatic explanation to his incorrect calculations lead him to clarify that he made a mistake in his calculations rather than the all the harsh comments that were previously posted.

he backed down finally.

Now it's the best airgun in it's category.
( he must have forgotten he said his would own my guns in no time...cause now it can only be compared to a .177 all of a sudden.. :roll: )

so only those with airguns made out of a nailgun, ducttape and his secret barrel design using exactly the same pressure , dimensions and ammo can try and beat him.
Anything else would be considered cheating I'm sure.

That would be considered a different category..

He never apologised for insulting me..
