The inquiry does not appear to have any association with 'Official' Air Gun Bench Rest competitions, as the range for that is considerably shorter. I forget the specifics but it is one or the other of 25 metres (27.5 yards) or 30 yards. I just can't recall offhand which it is.
In Airgun Benchrest competitions the old standard FWB300 comfortably holds its own. If you are only shooting in Springer class you're going to be OK. Everybody faces the same problem of a lot of gun movement - activity - and repositioning - for each shot. The physical design ergonomics and low cocking 'force' of the 300 even allows it to fare well in the 'open' classes.
In a full powered springer - I LOVE my 54s. I have a lot of other airguns - but the 54s are my 'go to' guns when I care enough to do my very best. The .17 for FT and AG Benchrest - the .22 for bloodletting. The .17 kills OK. Shot condition for shot condition the .22 flat out smites'em.
