Hiya mate, & to clarify !
I didn,t say they were 4.5mm , ( I said mine were 4.4mm )
I said " MY " Bahco was 4.4 mm. & IS, Smooth bored,
I care what your mate says the output was or is ! I stated that mine in the smaller calibre was all out at 4 Fpe !!! I acknowledge that a larger calibre might give slightly higher output ! But not the quoted figures ?
I might add, I take offence that you with " No previous knowledge " Of these guns would suggest outputs & Or any other information, Albeit prices , outputs, & Calibres when you haven,t a clue !!!!
I tried to explain ,!!!!!!!!
I being the owner of one & A repairer of a few, You seem not to acknowledge this,
To cut to the quick,
They with the 19th century valving & Unassisted mechanical aid " As regards pumping "
Were & Never will be powerhouses ! EVER , Tell your mate !
