Does anyone have experience with the Qiang Yuan domed pellets in .177?

My understanding is they are better known for their 10m match wadcutters. There isn’t even a single review on either Pyramyd or Amazon (orders filled by Pyramyd) but I went ahead and put some in my cart to try them out. They just arrived…I haven’t had a chance to try them out yet but I must say they are some of the nicest looking pellets I’ve ever laid eyes on. Very clean, no discernable parting lines or mold flashing to be found anywhere. Last night I measured 20 of them and they were all 0.1770” – 0.1775” which is as uniform as the very best JSBs I’ve ever recorded. That’s no guarantee they will do well but it is a characteristic shared by the best grouping pellets I’ve used over the years.
Anyway I’ll be testing them this weekend and will report back. Meanwhile I’d be interested in hearing your experience with them.

Im in...keep me posted

Interested as well.

I was given some Qiang Yuan .177 wadcutter pellets to try from the University of Nebraska rifle coach several years ago. It's what they use for their 10 meter competitions. Scary accurate @ 10 meters in my slowest break barrel.

Hi Mike, thanks for your feedback on the wadcutters. I ran across a few pictures of groups with them and that’s one of the reasons I decided it was worth the few dollars risk to try the domes. They also have a version they refer to as a round nose that is similar to the profile of a Baracuda Match but I didn’t get any of those to try. Maybe later if the domes do well.

Okay I got home a few minutes ago and grabbed the QB and set up a flashlight on the target at 30 yards. The first 5 shots were quick and went into a 0.45" group. I took my time on the next 5:

That works out to 0.7 MoA. I think that's a good place to stop before dinner.

A good friend of mine "K-Dog" that is a Exellent shooter has had good bit of luck with the domed ones in his HW97's and a couple other PCP rifles but if I remember the ones he has are 9.4 grain .177 that he got from AOA this summer. Hopefully he will chime in hear with a better report but with any pellet none are one size fits all! J.L.

If you look on the back of the container they are made in Czech Republic. So probably made by JSB. The wadcutter is made in China but these two the Streamlined and Dome are Czech. I have them both and are a pellet I want to continue to have as they are very good in my rifles. About the best in my R7. Tom Gaylord made mention of all three in his blogs and rates them very high.

Classic 21st-century marketing...the label on top says made in China and the label on the bottom says made in Czech Republic. Made in Czhina?

Wow great shooting.

I have heard of a few Dutch competition shooters that reported good results. They aren't used widely yet. Mostly JSB, AA and H&N for FT and HFT.
-
I have used the 9.5 grn and recently got a few tins of the 8.5 and they both are very accurate out of all my guns. I think they are the best kept secret in pellets a d most people don't try them because they are made in China. The tins I have I haven't noticed that they were made in Czechoslovakia I'll have to double check.

Jason that is fantastic accuracy from the QB!
Do you get that accuracy from any other pellets?
Hunter

Thanks Keith and Jo, it's good to hear that these pellets have worked well for others. I read that as an indication they have good QC and I'm likely to get good pellets again the next time I order.
Bayman, thank you sir!
Hunter, the QB is one I retrofitted with a LW barrel a few months ago. It flirts with MoA at modest ranges with a few different pellets when shooting from a front rest but shouldered (subject to heartbeat and respiration error), and that's representative of the best I can do with any rifle & pellet combination so I'm very satisfied with this result from the QY pellets.

I want to try them in a couple more rifles when the rain clears out. It hasn't let up all weekend >:(

On pyramid it shows head size of 4.50mm, can you measure a few to confirm if its correct or if they run big or small for stated head size. Most all my guns like 4.52 and bigger.

Mike, it's in the initial post:
Last night I measured 20 of them and they were all 0.1770” – 0.1775” which is as uniform as the very best JSBs I’ve ever recorded.
Equivalent of 4.50 - 4.51mm

Is your LW barrel choked? I wonder if the smaller head diameter would help the pellet keep up speed in a choked barrel, while still shooting accurately.
-
Hi Chris, yes it's choked.

Hi Chris, yes it's choked.
Fascinating. I believe you said that yours say made in the Czech Republic on the bottom. Which may mean that they are made by JSB? Do you have any 8.44 JSB? I have a tin of 4.53 size 8.44 JSB here. I'd be very interested in seeing how the velocity and accuracy is different between the two pellets.
My .177 Taipan shot .177 slugs 200 fps slower than pellets. Granted, that is a very extreme example of how bearing surface affects velocity...
My hypothesis would be that the 4.53 will shoot tighter, but at a slower velocity. However, the 4.53 should theoretically have a lower BC because the deeper rifling grooves will make them less aerodynamic. Whether the difference is measurable or not is another thing...
At the end of the day, none of these really matters, I don't think. Just a fun thought experiment? If you don't have any of the 4.53 8.44 JSB, I'm happy to ship you this tin that I have.

Yeah it will be interesting to hear where they are actually made. Their consistency suggests they may be from JSB but I don’t see any of the similarities that exist between JSB and Air Arms. They’re noticeably longer (0.270” vs 0.240”), the alloy seems harder, the surface finish looks different, and the geometry inside the skirt is different than any I’ve seen from JSB.
About head size and its effect on accuracy, I’ve tried for years now to correlate a barrel to having a particular preference but at this point I’m convinced it’s a nearly useless predictor of what will group well. Instead there seems to be a fairly generous range of head sizes over which a barrel may group well. One batch of magic pellets will show the head thoroughly engraved and another batch of magic pellets show only slight burnishing where the head skates along the rifling. I don’t know who coined the phrase but it seems that as long as the head is big enough to “ride the rails”, and therefore not subject to tipping off axis, it has as much opportunity to group well as any other. At the other end of the extreme, I don’t want the head so big that it drags the walls (groove diameter). In other words, the perimeter of the head between the rifling marks should be undisturbed.
The only consistent feature of excellent pellets I have found is that they are all sized as closely to each other as possible. Perhaps what that means is if the heads are extremely consistent, so is everything else. Weight, geometry, balance (lack of voids), absence of parting lines and flashing, etc.
So if I get a tin and measure a sampling and they all come in at 0.1765”(4.48mm), I know they have every bit as much chance of printing tiny groups as another tin that measures consistently 0.1775” (4.51mm). Sure, the bottom end and top end of that range will vary a bit from barrel to barrel, I’m just saying most barrels don’t seem to need a specific ideal number.
And of course paradoxically, just because a tin is supremely consistent does not mean it will group well. It might, it might not. On the other hand, I’ve never had an excellent tin whose heads varied by 0.0015” (0.04mm) or more.

Okay I had a few minutes of daylight left when I got off work so I took out the SPA PP700S-A and the Crosman 2240 .177 HPA conversion to try a quick group with each. Same distance as before, 30 yards. The PP700 was looking good at first but had one that went wide left and ruined it. It's detuned quite a bit to sub-600fps so it might have been the wind. I'll try again under more favorable conditions.
The Crosman carbine put 5 of them in a 0.37" group (1.18 MoA). That's great for a gun with a substandard trigger that I haven't shot in a while so that bolsters my confidence in these pellets. Looks very much like they may find their way onto the short list.
