Had cheapie Benji mounts, a Burris scope with long eye relief, and a butt riser that just came in from China. It works alright.

Looking good Dan. So what aren't you liking about it? Since you say "alright"

You are perceptive, Rob. It shoots alright, but not awesome. My expectations may be skewed, though. Sometimes I subconciously play favorites where a half inch group looks great from one gun and terrible from another...
This 392 is pellet-picky. It throws a lot of flyers with H&N, JSB, and Crosman pellets, but it does ok with RWS pellets at mid power. It shoots well enough to reliably plink plastic golf balls out past 25 yards, but it doesn't group as tight on paper as I would prefer.

Nice looking 392 you have there. I guess you never know from one gun to the next, even of the same brand, what pellet it will prefer.
My 392 shot Crosman piranhas great until all the paint overspray was out of the bbl., but groups opened up wildly after that.
I ordered a sampler pack of gamos a couple of weeks back just to try.
I was really surprised when the domes(hunter) pellets just made a very small black hole at 20 yds. benched.
Magnum energy pointed shoot into the same tight hole as the domes.
The master points started out shooting like that, but I ran into some of those with bigger heads and had flyers.
Also the TS22’s at 21.75 gr. We’re literally trying to get into the same pellet hole at 20yds....but, seemed to have more lag time in the bbl. and had to really watch my follow through with them.
I was pleased when 3 out of the 4 pellets shot so well.
I hesitate to recommend them at this point, but their holding up in my rifle just fine.
Shooting over the top of a car standing on a 2x4 lol, it put the domes in 1 1/4” at 50yds. 5 shots and the magnum pointed in 1 1/8” with 5 shots and 4 of those were well under an inch.
“Might” be worth a try?
I will add my brother’s hatsan 95 wouldn’t shoot them at all....too tight for his chamber.
I tried them in my 392 simply because i had already tried gamo rockets and red fires in mine and they worked well too, but not quite as well as the domes and magnums have.
I just mentioned my experience with these since you said you’ve already tried some jsb and H&N in yours.
Might work for you... might not.

Thanks for inspiring me to try some new pellets and retry some old pellets this morning, buddy.
I recrowned the gun yesterday, which may have helped it be a tiny bit less unworthy - best 10 shot 10m group shrunk from .330 to .310 inches. This morning, I shot some more and finally hit the jackpot with JSB 15.89s- 10 shots at .250" ctc. I remember shooting poor iron sight groups with them when I first got the gun, but they are working now!
I resealed this gun and did the basic two-spring mod and extra center oring with Teflon on the threads. It was shooting 575 fps with premiers when I got it, and now it's doing 625. With the JSB 15.89s, it's doing 503fps on 4 pumps and 615 on 8. So I'm feeling good about that.
Next step is the trigger. I have a Supersear I can drop in, or I might just reprofile the OEM sear.
Edit:**pic of single target is before recrown.

Good to hear about the improvement with the crown and the jsb pellets.
Mine could benefit from a trigger touch up. It’s a bear from the bench. It breaks like glass with zero creep.... but at about 5 pounds.
Way to heavy from the bench. I never seem to notice it when hunting though.

I dropped the Supersear in this morning. It lowered my pull weight from 4lbs 3oz avg to 3lbs 2oz. I then proceeded to shoot a group about the same as my .250 effort from yesterday.
I have a 397pa at my girlfriend's house that I reprofiled the OEM sear on. I'll get a weight measurement on it next time I'm there.

Sounds great Dan. How does your 397 shoot?
I’ve thought about getting one at some point.

The 397PA is a 1997 model. It is accurate, and not pellet picky. I did the 2 spring mod and extra middle o-ring mod on the valve and threw a peep sight on it. It does 600fps with JSB 8.44s with 3 pumps and about 800fps with 8 pumps and 850 on 10 pumps if I recall correctly.

Attached is a pic of the reprofile method I used on the sear.

Nice...made me want one even more.
Those are some nice FPS. no. on yours.
Gotta love those Benji pumpers!

Sorry to hear that Dan. Yes I got lucky on mine, even being a newer 2014 model. When it arrived from amazon it took a beating upon delivery. After, getting the barrel cleaned it shot well. I got lucky and got a good one that likes darn near anything I feed it. It has its favs, but its harder to find a pellet it can’t shoot well.
I thought maybe you weren’t liking the barrel clamps for the mounting of the scope. There are couple choices as you’ve probably stumbled on by now. Most my shooting is pesting and I prefer the peep for that. Looking at where you have your scope located have you thought about the Baker mount? I prefer to only use those clamp mounts for small tubed scopes.
