Recent few years the JSAR has been my .177 & .22 slugger. last year picked up some test barrels from Sabre/Karma having a 27 1/2" long 6 groove .25 cal in the lot.
Having tested with pellets previous with much success, it just was reinstalled on the JSAR Raptor for some slug testing.
Now this was not an accuracy test but one of how much Juice it has when shooting HUBEN 43.00 grain Flat base slugs ???
on @ 1900 psi we're at @ 860 fps .... so, we start raising the reg pressure until reg was nearly maxed out at 2400 psi ( Ninja Adjustable reg ) and the 43 grains are at 920 fps !! for an astounding 80.8 fpe
Taking a few shots out in the front yard out into big water puddles at @ 115 yards .... the accuracy appears pretty good ( Tho not zeroed, on bags or really confirmed ) but landing with a big splash really close with similar POA.
Had no idea the JSAR in .25 cal could muster that amount of Juice .... Whoa !!
