Cutting The Choke Off An FX Slug Liner ?

Cutting off the choke doesn't mean that the accuracy is going to be better it is kind of a roll of the dice either it works or it doesn't and then barrel might as well be tossed 

heavy-impact,

I've done it a couple of times to turn poor-shooting "old" .22 STX 700mm liners into 600mm liners. I had a friend with a metal shop cut them using a lathe and recrown the new muzzle. One shot pellets much better than the old 700mm liner and shot slugs (almost) as good as a new 600mm Superior liner. The other 600mm was not as consistent with pellets as the first one(I think because QC was not as tight on the "old" STX liners and almost every one was different and shot differently), but still shot (some) slugs well. I wanted another 380mm liner, so I chopped that one down again from 600mm to a 380mm liner and it performs (nearly) as good with pellets and slugs as my 380mm Superiors. They do get way dirtier quicker than the new Superior liners though.

Making lemonade out of lemons because those old 700mm STX liners were useless to me and nobody wanted them after the Superior liners started coming out. 

Might make sense to get a feel of the barrel by slugging it first. 
If it has loose spots or is lose up to the choke….I don’t see how it will be accurate, unless u find a slug or pellet that would fit. 

I have cut other barrels with chokes off and had some success but Ive never tried a fx liner it still can be a craps shoot but if the barrel is all ready inaccurate you have nothing to lose 

I've only done .22 caliber because there is a wide enough range of .22 ammo with different weights and diameter sizes to able to find something that the liner shoots well. Slugging the barrel was helpful to "weed out" some diameter sizes of slugs.

Why an earth FX chokes liners? There is only one type of barrel that requires choke and that is bad one.

Give it whirl it is like .002 of a choke cant imagine it is doing a whole lot I'd be more worried about the crown after removing the choke 

I say cut it off. .001” maybe a little on the lose side but you won’t know until you try. It just might be stellar. 

The difference is 4 thousandths, unless I’ve forgotten how to math. 

.0 is tenths .00 is hundredths .000 thousandths. .0000 is ten thousandths of a inch how did you get 4 thousandths of a inch ?

See, I did forget how to math, 4 ten thousandths ? Do I get a do-over?

So….I arrived at that answer by obvious mistake, and now you know. 

I see it now, the brain fog is extra thick tonight.
