Hello cole5169, i was wondering about the velocity numbers.  I live at 5030 feet above sea level, and it affects my springers at around 15 to 18 percent, i loose that much velocity over sea level velocitys.  Now i have a litttle 1377 that does 480 fps where i live using a crosman 7.9 hollow point, and i think that is a bit low for the average gun, so altitude must be affecting the pump up guns.  Know anything about that, do you live at higher altitude?    fb

Arkansas Man,

Yes, all pumpers need oil. Not an oil bath mind you, but some oil is good!
I guess if you never oil it it would become hard to pump. I've always made sure to oil all my pumpers and have never experienced one getting hard to pump.
Here's a link to a copy of the owner's manual in case you didn't get one...
http://www.crosman.com/pdf/manuals/B392-OM2.pdf

I cleaned the barrel on my 392 with a brass cleaning rod for .17 caliber rifles using a .22 barrel swab and a plastic jag and patches. I know a lot of folks don't like to use rods, but sometimes that's all you can use. The barrel on the Benjamin pumpers is brass, so don't get too aggressive with cleaning it. I cleaned mine when I first got it and haven't cleaned it since.

As for storing the gun with air in it, I'm not sure it matters with the cartridge valve like in your and my rifle. Benjamin and Sheridan used to recommend it, but since Crosman took over they say not to. Some of the tuners say to keep air in them. I generally try to keep air in my guns, but sometimes I forget.

Hello to you airgunandy, would like to ask a question or two, could learn it on my own but that is not always the best or easiest way.  I took my 392 out for the first time yesterday afternoon.  I tried it with open sights, i did not adjust them but used them the way the gun came.  At 25 yds. the best gps. were with RWS hollow points, i had a couple gps. measured four shots at 3/4 inch and the fifth shot making them 1& 1/4 inch gps.  But due to my eyes the sights were blurrrrrry.   I did not do anything to the open sights until today.  I think it will do better now since i tightened and adjusted for center.  Now it shoots almost one hole at 13 yds. (not quite the limit of my backyard but i didn't want to get crazy with houses about).  It seems to me that one should first adjust for windage on the 392, then adjust for elevation, seems that the elevation screw is rather small, and would need to be lock tited in place, is that sounding about right so far????   I tried the superdomes and crosman copperheads and they did not do near as well as the hollow points.  Question, have you tried Beeman FTS pellet or the crosman hollow points that come in the can,  and if so how did they do????   I think i may put in a small pellet order tomorrow.  LOT of questions,,,,, but about the oiling,,,,,, no problem oiling the hinge joints but have you noticed the little hole that says (((air hole do not oil)))????  My question is this, am i supposed to oil the valve or stay away from that area with pelgun oil?    thanks     fb

Redfeater, you mentioned the williams peep sight.  I did a read of the reviews on it at pyrimid air and i think i concluded that the 392 is, from the factory drilled and tapped for the sight, is that correct?  As is look at my 392 on the rear of the action about two inches frome the reari find two holes.  

Now on the left side of the action i find two holes and they are about 2& 1/2 inches from the rear of the receiver, and these holes are coverecd with a small tin plate.   If you don't mind tell me are either of these sets of holes used in the mounting of the williams peep?  

And is necessary to remove the factory sights if i mount a peep?  

if youhave one of these sights on your rifle how do you feel about sending a photo or two to my email.     fortblt@msn.com      thanks    fb

The holes on the right rear of the receiver are for the Williams peep. The two screws and plate on the left are used to adjust the bolt fitting into the chamber. The factory rear sight will need to be removed if you install the peep sight.
Been thinking about getting one to try myself, but haven't taken the plunge yet.
