Golfer,
The .25 caliber FX slug liners shoot too. Just not a lot of videos of people shooting them. Bob O obviously shoots the .22 and the guys in South Africa can't have .25 caliber air guns so they also shoot .22's. However, the 30.4gr, the 31.5gr and the 34gr. that Dale makes shoot great out of the 600mm FX slug liner, at different velocities of course. I've got a .25 caliber slug liner coming in 700mm for my MKII also. I'll test a bunch of slugs for that liner when I get it. I'll post the results on AGN for everyone as I go. I'm not trying to push the .25, I don't care what you shoot. LOL I just wanted to let you know that if you like the .25 caliber, don't give up on it for shooting slugs. There is a lot more testing to be done!
