I think 18 grain JSB is usually magic in most guns.
I'm a PCP guy myself because I have a Bauer compressor. Unlimited fills.

I've noted that trend about the JSB 18 gr in the 22 airguns.

MM, what scope mount is on your Hatsan?

It's this one,

Dimensional info is here:

Thanks, does that replace the alleged Weaver rail that it comes with? And, do you like the height, as it relates to the adjustable cheek rest?

Appreciate you guinea-pigging this!

This base mounts to the provided rail. The provided rail appears to be riveted and/or welded in place, pretty solid. it's not something you would easily remove.

The height is ok with me. It could be lower.

Hawke makes a lower version too,

The High mount is 1.4" from base to centerline. The Medium is 1.0" from base to centerline. I believe my scope would fit with the Medium, but probably not with the lens covers.

Although I typically like a low scope mount, the higher mount in this case (low velocity air rifle, rainbow trajectory) creates a bit further zero with a max +/- of say 1" from LOS. So it's OK with me.

Regarding the mounts, another thing that favors the high mount over the medium is the location and operation of the safety.

You need some room to get your thumb on the safety, so that favors the higher mount.

Appreciate it.

Mild day in the 40s today so I was shooting the Hatsan 125 some. Got about 500 pellets through it now.

Chrony shows a bit more speed than when new.

- JSB 18.13 gr, 840 fps, 28 FPE
- Crosman 14.3 gr, 935 fps, 28 FPE

40 yard target. Have it zero'd with the JSB 18.13gr. Slight L to R wind, 5 mph or so.

Looks good.

JSB 15.9's might run around 880, and be smack in the middle of the optimum velocity window for accuracy.

I'll have to give them a try.

I've got around 2000 each of the Crosman 14.3, and JSB 18.13 on hand, so pretty well set for a while, but curiosity will probably get me.

I keep some 15.9s around because none of my rifles will get the 18.13's into the 850-900 fps range. Thats my goal - to buy or put together a "normal" weight rifle (9 pounds or so) that launches the 18.13's in that 850 range, accurately. Think of it as a "light heavyweight".

There are plenty of reports of the Hatsan 125 & 135 exceeding 30 fpe, so even 900 (32 fpe) with an 18.13 should be doable. The 9 lbs goal might not be though....

My "best" .22 is a gas ram RWS 350. I haven't chrony'd it but it should produce 725 fps or so with those. Not quite what I'm looking for. Magnum complex....? Check!

The sound of pellets hitting the trap tells me that the 350 does well with the 15.9's, and that makes sense. It certainly has more pop than my Hatsan 95 which is 800 fps with a 14.3. I'm guessing 800 with the 15.9's for the 350. That puts it in the 22-23 fpe range and in a good velocity window to hold on to that energy.

As an aside, you don't read much about the NTEC guns but I like mine very much. It is very well made, has a fine trigger, shoots strong but isn't ridiculous to cock, and so far has been impressively accurate (at only 9 yards, but we will soon see what it can do at longer range)
I dont remember if your 3500 is a gas or coil spring gun, but either way it should be nearly identical to a 350. You might want to try some 15.9 JSBs in that rifle too.

I've got a couple tins of the JSB 15.89gr Hades pellets. They were one of the few pellets that shot well in the RWS 3500.

Upgraded scope mounts on the Hatsan 125 22cal. Went with Medium SWFA SS rings with the 1" inserts. Seemed like the most solid mount up to utilize the weaver slots in the mounting rail. Height is good for access to safety, but not so high as to need to raise the adjustable comb.

I like it. Re-zero'd at 20 yards.
