Hmmmm....looks like my Trail NP2 likes all three pellets that I feed it.
My Summit doesn't group all that great--maybe 2" or so @ 25 yards with a flyer here & there. My shroud also loosened up, a lot, before I noticed it. I thought that was the source of the unsatisfactory accuracy. I tightened it up as much as I could, keeping in mind that too tight could crack the plastic cone piece at the end. The cap for the shroud is different than the ones on my other Benji/Crosman rifles--no hex that can use an allen wrench on so it's difficult to gage how tight you're getting it. I ended up using channel locks with tape wrapped on the jaws trying to protect the finish, still managed to scratch some paint off the cap. Now I'm wondering if the darn thing is too tight. Could that effect accuracy? Crosman must use as special tool to tighten the cap. There are small indentations in it, I tried to use the points of needle nose pliers--no workee. Any suggestions or comments welcomed.EdI've used CPHPs, JSB 15.89s & H&N FTTs 14.66 . All performed about the same as far as grouping. POI changed of course.

That part did not come loose on mine, the entire shroud lossened up, where it seats against the part that breaks to cock the rifle. I snugged it back up tight and then backed it off a little after the accuracy slipped. Hopefully I will be able to play with it more today.

Pretty hard to do that with the tiny bit of area. Don't know why the got rid of the hex, maybe to prevent OVER tightening. Ed

Pretty hard to do that with the tiny bit of area. Don't know why the got rid of the hex, maybe to prevent OVER tightening. EdThis will be hard to explain. The little piece at the top did not unthread, it stayed in the shroud and the entire shroud twisted and came off. With the little top piece, baffles and all staying in the shroud.
Do NOT use Loctite on the baffle! Loctite and plastics do not get along. I just tighten it by hand until it hard stops. You really cannot overtighten it. Sometimes, the shroud will twist without coming loose. This can affect groups. When it happens, I just twist it a little more. Mine likes the JSB Junbo Exact 1813 the best.
Thanks. Thats good to know since I can't even get the baffles out of the shroud, the whole piece comes out as one, baffles and shroud. I didn't know the threads on the baffle were plastic. I may need to try something, it works loose fairly quickly and messing with it seems to effect accuracy.

The shroud on those isn't set up quite the same as the Trail NP and XL but they both do put tension on the barrel and change POI when the tension changes. That is to say it changes on the Trail series and I don't see why that would be different on the NP2 series. I asked Crosman about the Trail series and they have no spec for the shroud retainer tension so I just found a tension it liked and used some temporary thread locker. I can still take it off when I want to but it doesn't work loose.
Thanks a bunch for that info. What thread locker did you use? I was thinking a dab of clear nail polish since the threads on the baffles are plastic.
