RAW TM 1000 POI changed

[rcolletti]

Hello all, last year I purchased a used RAW TM 1000. Up until this month it has been shooting like a laser. At last week’s competition, sighting in at 27 yards it is right on. At 50 yards it's supposed to be -1.5 to hit center but it ended up being -10. Same with 10 yards, my hold point was -3 now it's much more. Any ideas what caused this, could it be the regulator? Is this something I should try to fix or just send it in for an overhaul?


Thanks in advance for your suggestions.

A chrono run would be informative.

Yeah…you need to confirm the gun is shooting slower before any conclusion what might be going on.
Does the gun sound different? I’ve had a reg fail on me, essentially you get bottle pressure right on the valve. Hammer no longer had enough oomph to open the valve. Gun sounded really quiet..was around a 300fps loss

agree with all of the above.

Reg issue is possible, but for such a sudden and significant POI change, I doubt it. I once had a sudden and drastic POI change in my RAW, and it turned out to be a dirty hammer assembly. I disassembled it, cleaned and lightly lubed it, and the issue has not recurred. And, the first thing I eliminate with any accuracy issue is a dirty barrel. I've had a dirty barrel cause problems I would never have guessed.

Yeah…I’ve heard of that too. Personally never experienced it though.
Also a very simple fix.
