Hello,
Trying to join the 100 yards club ( with modesty ) , I've got a FX Boss .30 cal. Put a Hugget moderator at the end of the shroud and a Hawke 8-32X50 scope.
I tried the JSB 44,75gr , FX 46,30gr and Baracuda 46,30gr. None of these gives me the expected result.
The target is at 50 yards , my usual range. The problem is that 1or2or3 pellets in a row go through the same hole ; then the followings hit a bit low , a bit left or right , no more than 3/4 of a inch , but I was expected much better from this gun.
I can't explain the reason; maybe it needs more break-in (I'shot mo more than 100 pellets 'till now ) , barrel cleaning, pellets sorting , lubricating, resizing... . I shot outdoor , with no wind . Maybe the shooter himself is to blame , but at this range I put all the shots into a dime with my Cricket bullpup , Cricket carbine , FX wildcat and Vulcan , all in .25.
Maybe the .30 cal doesn't fit me :(.
If anybody could give me an advice.
By the way , did anybody try a Edgun R5M in .30 . Just because I like bullpup :D, even in .30.
Thanks

First thing is to eliminate the moderator. Try the gun first without any modifications.
Could it be clipping the pellets?

Yes , that's an idea . A moderator , in most case and even the pellet doesn't touch it , has an effect of the POI . I put a moderator on my cricket , making an adapter to screw it at the end of the shroud. Not an easy job because the end cap was epoxied to the shroud , not screwed. The first adapter was not perfectly in line with the bore , and the results were catastrophic. I built a second adapter more accurately , very tight fit , now the gun shoots very well.
I'm going to my shop to make some tests.Anyway this gun is quiet enough without moderator . Keep you in touch for the results.

Marko , your suggestion was great ; you got it: the gun shoots now much more accurately : five shots in a 1" diameter . The cost is...the noise , which increased quiet a lot . Now I have to check what the noise is at 150 meters , that's where my nearest neighbour is :D . In fact , the noise coming from the impact with the paper target is the one which upset me the most , as I shoot from inside my shop with the door half closed. Moreover I've built a kind of absorbing wooden box , filled with sand bags to damper the impact….yes I'm very fussy about noise ;D
Maybe the shroud of the gun could be improved by drilling some very little hole near the breech; Ernest Rowe ( a great airgun tuner , plenty of videos on his site ) did that trick on some of his guns .
Another trick is to run a mower engine during the shooting session , to mask the noise .
Well , let's go back to shooting ;D

It has be documented over a "Long Period of Time" the FX Smooth Twist Barrel "DOES NOT Like LUBE with Pellets, and is not a slug shooter. Virtually EVER! And is confirmed by FX themselves.
Perhaps the New "X" Barrels with be different, but not the smooth twist. ;)

OOOhhhh , that's it . Yesterday I've cleaned and lubed the barrel ; moreover , I've lubed my pellets !!!!
So I was all wrong and wondered why the gun didn't shoot accurately ::) .
Now, it's maybe a good idea to put a few patches through the barrel (smooth twist) to remove any trace of oil and wash the pellets in soapy water as well .
Thank you for this advice.
Never too late to learn!!

That was it : a good barrel cleaning /degreasing and dry JSB 44,75 gr pellets ; target at 53 yards , 9 shots,
the last one fired too quickly :( .

Nice, good you got it working.

Thanks , I forget to say that the moderator has been put on , just enlarged the baffles a bit to be sure the pellets don't touch.
I drilled two rows of 7 holes at the beginning of the shroud , underneath , about 1,5mm diameter ; then put a roll of fine metallic grid inside the shroud to decrease the blast of air passing through the holes.
Works fine . Now the gun is quieter….and accurate.

Very happy she is working for you now! Love an accurate AG. 8)

nice job with the FX

Try stuffing the target box with old clothes. I shoot old socks and underwear in a cardboard box. Only thing you hear is the pellet going through the cardboard. Maybe it's all the latex in there. :D
