That made interesting reading thanks. I have owned in the past two HW97k's, a .20 for a short while and a brand new .22. I have had for a few years now a TX200hc MkII and a B40 both .22. For me the TX is the noisiest in terms of muzzle rapport, the B40 is noticeably quieter and can't remember the HW being noisy. Out in the open fields they are all quiet enough. The TX for me feels more comfortable and natural to use, stock on the Bam feels dead, can't really explain? The stock on the HW felt unrefined but having an HW80 since 1986 this was not really a problem
All three are deadly accurate and have little down sides but all are worthy guns
For me personally my favourite is
UL: TX200hc
BB: HW80k
