What do I do

[62hotrod]

  I did a complete tune on my Air Hawk Elite 177 about two weeks ago. I did a complete trigger job, Vortek PG2 kit, Soft bedded the action, plus a few other things. I used a high grade high moly content grease for lube. Not having time to shoot much it has been a struggle to get maybe +- 200 rounds through it. I'm still getting just a small hint of smoke in the barrel after a shot. I'm getting decent accuracy, but I can't help to wonder what if. Should I continue trying to burn it out by shooting it, or tear it down and try cleaning out a little grease.

If after you shoot it you have a light brown haze in the bore just keep shooting it, if you can't see out the other end then tear it down and remove all but a light film of the lube, should be able to feel it but not really see it...

  Thank You Mike, It's just leaving a haze in the barrel sometimes and sometimes it's kind of dark. I think I'll open it up and clean out some grease. It's to easy of a fix to keep wasting time trying to shoot it out. I'm getting a pretty good fps spread I hope that'll tighten it up some anyway.

sounds like just a hair to much lube, check piston seal also, even a small scratch can give goofy problems in some rifles...

  I broke it down cleaned most of the grease from just the piston. When I reassembled it I put the piston in all the way in and put a little grease at the end of the skirt just enough to help the buttons. I shot it some Sunday first couple shots left a very light haze then it went completely smoke free. I had a couple dime sized groups at forty yards and one holers at twenty and thirty yards. If it'll just hold up for the long haul now. I chronographed it last night and got these numbers. i question the accuracy of the Chrono, I was using Chrono connect on my smart phone. I have no idea if these numbers are good bad or what, that's another learning phase I need to under take. Please give me your opinion. Thank You

  Not an expert on the D34 or clones but those numbers don't look bad especially if you continue with that kind of accuracy , also the FPS may pick up a little as everything wears in and mates. Remember accuracy trumps power every time "a miss is as good as a mile" and close doesn't cut it if you are hunting  or trying for 1st place at a match
