FX Impact pellet probe problem

[Keyman62421]

I just finished drilling out the broken screw on the pellet Probe block, tapping and installing a larger screw. I noticed that although the block can fit either way in other words it will reverse . the probe screw is offset by about a 16th of an inch I failed to measure or notice this when I took it apart but I took some time to measure my transfer port clearances and put the short end to the rear my gun. loads better shoots better than it ever did I think either the screw was broken when I bought the gun or the probe wasn't straight when I bought the gun. The gun did shoot rather well but it had discrepancies and always had some slight loading issues. The reason I was messing with the probe is that I bought a 700 mm Barrel to be delivered in the future and I thought I might want to figure out if this thing would come apart. Good thing I did. Has anyone else noticed this variation on the probe set screw?
after repair and little tuning I put 14 out 16 mark 2s in a pellet tin lid @ 110 yds.10 rds in 1 1/4"

I had I problem with mine being loose and not properly aligned to the barrel. You put a bigger set screw in the block and probe.. awesome idea and I'm come tomorrow morning I'll be on the drill press doing the same thing.
I actually didn't have any loading issue. My problem was it was really loose so snugged it all up. Well when I snugged it up it made the probe not align with the barrel. I think that had to do with the flat head bold on top cause I loosened that and the whole probe shifted in place. 
I'm thinkingif I drill and tap a bigger set screw it should help like it did for you. I'm hoping. I haven't actually took the set screw all the way out so I don't know if it's broke, bent or anything good time to find out

did your accuracy change? I went from 1in groups at 50 to less that 1/2in at 50 now. I was amazed how much the probe plays a role in accuracy.

Take the cheek well off then the port side plate on the shoulder rest and you can drop the pellet probe and block right out of there you have to take the screw out of the top of the pellet Probe block pay attention there's a difference between front and back on this thing at least there is on mine

I wish I Would get all this posted at one time. I drilled a 1/8 inch hole through the threads and tapped it with a number 6 tap & set screw
