HP let's not go there..Tally/Leupold...ughhh...I think the only ones I have not sworn at or about are... Warne...I Think, don't quote me & don't take that as an endorsement...Back To Tally...I have been trying to get a replacement snapped off screw from one of their Fancy split styles on a Sako HB Varmint for years...The money we spend on scopes. & The Mounting systems should perform much better for the price we pay..It is not rocket science, giving properly hardened & tempered mounting screws..Mike
