FX impact mk3 .22 cal

[cain_moa]

Whatsap guys
Recently,
my and my friends we decided to switch from Daystate to FX
We chose the .22 caliber impact mk3
And our goals is to shoot heavy slugs
40 gr at 1000 fps
We do not have experience with fx
so we found it difficult to choose the appropriate gun, type and length of the barrel, with the pieces that must be in it to determine our targets
Any advice guys
And are there a problems with the 800 mm barrel ?

You must be very lucky to get a good liner. I had many of them and just one was a MOA shooter.
