Had a little time this afternoon to answer my own question regarding which pellets shoot well out of the Leshiy 2 350mm .25 cal.
the photo above is a target printed on photo paper from Joe B off his site.
Bipod and a shooting bench was used at 28 yards (This is the max allow in my back yard)
Each numbered square is one inch.
A is first shot group of 8 shots, B is second shot group of 4 shots (tried to take it a little slower between shots to concentrate).
JSB Exact Kings .25 25.4gr box #1 and #2 A group was not bad, B group was better, took a little more time to aim and more careful not to jerk the trigger.
Benjamin Dome 27.8gr Box #3 and #4 A group was surprised that these cheap pellets for my old marauder did so well. B group just as good.
RWS Super Dome 31gr Box #5 and #10 A group was good except two that just went left and right. B better ,but all over.
Beeman Kodiac Match 31.0gr Box #11 and #12 A group was simlar to the JSB's but I dont know what happed in B group, still fair
Beeman Crow-Magnum ? gr Box #13 and #14 A group was all over the place, B group was a little better (these are big and heavy pellets with hollow pointed)
H & N Baracuda 31.0gr Box #15 and #20 A group performed just behind the JSB and Beeman Kodiak Match. B group had one shot off.
Box #21 and #22 was just repeats of my basic standard JSB's Performance consistent.
Im not a great shot, but these are the result I got with a little testing, the Eunjin .25 35.8gr flat head pellets by air venturi and the .25 43.2gr pointed head pellets would not fit into the magazine.
