soontjen10 Posted September 21, 2014 Report Share Posted September 21, 2014 Hi all just bought an at44 in .25 cal, i put some hawke scopes on went out to zero it (nice gun buy the way) couldn't get it to zero, so took the moderator off which is a sako and got it grouping very well, put the sako moderator back on and all over the place. Any help would be appreciated. Thanks in advance Gary. Quote Link to comment Share on other sites More sharing options...
casts_by_fly Posted September 21, 2014 Report Share Posted September 21, 2014 Probably clipping the inside of the mod. Pull it apart and see if there are any marks on the baffles or exit port. Rick Quote Link to comment Share on other sites More sharing options...

onatangent Posted September 21, 2014 Report Share Posted September 21, 2014 Top tip to avoid jams when loading is with the magazine inserted for the first time pull the side lever back as if to engage the safety again. This indexes the magazine everytime. If not there is a 50/50 chance of the pellet probe fouling. I followed the manual initially which just says, insert mag, click and roll back to index to stop. As per other post strip mod down. Has ballastic matting, nylon hair curler looking pieces and a couple of washers so they might have jiggled when it was put together.

soontjen10 Posted September 21, 2014 Author Report Share Posted September 21, 2014 Stripped the mod down its a one piece aluminium tube all drilled for baffleing drilled the centre hole out to 10mm as it looked slightly bent and 8.5mm where pellet comes out and now sorted. 9 shots grouping the size of 2p piece.

Sha Bu Le Posted September 21, 2014 Report Share Posted September 21, 2014 Did you buy them new, was the mod fitted to the gun when you bought it, if new maybe you should have taken it back. It could affect any warranty claims you may have in future. Anyhoos glad its sorted. Quote Link to comment Share on other sites More sharing options...
bruno22rf Posted September 21, 2014 Report Share Posted September 21, 2014 With the loopy trajectory of a .25 are you sure that the pellet is not dropping over the length of the moderator? Quote Link to comment Share on other sites More sharing options...
soontjen10 Posted September 21, 2014 Author Report Share Posted September 21, 2014 Sorted now but the rifle and mod were second hand as I've said in an earlier post grouping nice now thanks Gary Quote Link to comment Share on other sites More sharing options...
hoggysreels Posted September 21, 2014 Report Share Posted September 21, 2014 Sounds an interesting choice. I'd guess it will be great for ratting and the Grey Squirrels ... l'd like to try a .25 myself. Quote Link to comment Share on other sites More sharing options...
