OK I finally go some trigger time with the Diana 75 . First impressions follow ...Bear in mind I shoot almost nothing but my FWB so it'll be what I compare it to .
Looks . OK both look incredible , each has its own niche . But both have the all business approach to Airguns but do it with Style !! I like them both .
Trigger , both have plenty of adjustment and can be set light . I didn't play with the Diana much ...It is COLD HERE . Both are very nice . Not really fair comparison because my trigger on mine just breaks without me thinking after 15-20k shots . Little secret .. When I sell on of my personal FWB rifles, I keep my trigger group Everytime ..lol
Speed . Again it's kinda a wash . Mine handles the 10.3 pellets MUCH better . You can see spiriling with the Diana , they both shoot the lighter pellets GREAT !! Photos below . FWB is a Little faster but not a ton ..Plus mine has a Macarri spring.
Cocking effort . This on goes to the FWB . Not by a huge amount but it is lighter . Trade off is with the Diana you don't have to latch and unlatch lever . You just pull it open , and push it closed . But it does take a little more effort .. That being said they are both VERY easy to cock .
Loading ... If you load right handed ( I don't ) then the Diana wins by a mile . Absolutely no obstructions between you and the breech . Left handed it's about the same .
Ease to scope ... The Diana is much longer between scope rail and port so a longer scope can be used with obstructing the breech . But the FWB has longer grooves . The Diana uses a quality machined riser to attach ring ..FWB uses grooves machined in reciever.
Firing action . Hen the trigger fires on the Diana it literally feels like a PCP , there is a slight quiver and then a hole in the target . FWB entire action slides rearward to absorb any recoil . Both are amazing , but the Diana in NO WAY feels or sounds like a springer . If you to shoot it blindfolded it is almost like a SSP . Except for the slight firing noise . Both are plenty quiet !!
ACCURACY the BIGGIE . It's too early to tell ...But both are Badasses !!!

These were shot with a north wind hitting me in the face ( vertical strings) and I am dying to see what it'll do in light wind . The Diana is absolutely astounding . Best way I know to put it . I've only fired 3 springers that made me go WOW in my head when fired for the first time . ..HW30 , FWB 300 , and now the Drain 75 . It's THAT GOOD !!! I also realized that a Hawke 2-7 is WAY under scoping this gun . My Leupold gonna have to do double duty for the video .
