SK Semi Auto Rifle versus Eley Bullseye X

I bought a couple of bricks of each to try. Both are extremely accurate out of my Hammerli Xesse SF , after trying a few rounds. I think the Bullseye X is a little more reliable but I looking for others opinions.

In my experience the SK rifle-type cartridges are problematic in a pistol. SK Standard (yellow box) is fine, but the others use a slower-burning powder which kicks pretty hard and tosses more soot/still-burning-powder around. It shoots quite well, however! I just think it's hard on the pistol.

out of 6 pistol .22 LR types, that i tried in my in my Hammerli SF

the SK pistol Match is the most accurate.  FYI 
Good Day

I think that semi auto rifle is even better. Only thing close was the old Cone Shaped bullets they sold in the red box a while back. 

I chose the eley because I had a good experience with the CMP Eley ammo.
