VALUE FOR MONEY
Qiang Yuan 8.18 Grain .177 caliber pellets are labeled as “Olympic Grade”. This is because they have been used by Olympic-level competitors with success over the years. These pellets have a very high reputation among the precision air rifle shooting community.
These “QY” pellets are individually packed in foam sheets, 100 pellets per sheet. Two sheets per package.
Manufactured by Zhuhai Qiangyuan Sportsgoods Co. Ltd. in China, Qiang Yuan 8.18 Grain .177 caliber pellets are expensive – as you would expect from a product with this reputation and background. The Street Price is $16.99 for a tray of 200 pellets, making the cost per pellet a hefty 8.5 cents.
Of course, leading online retailers offer “buy four tins, get one free” offers, so the price could be correspondingly less if you buy in bulk.

COMPARISON TO MAKERS CLAIMS
The Qiang Yuan 8.18 Grain .177 caliber pellets tested by HAM contained 200 in the pack, exactly as claimed by the manufacturer.
The claimed weight of Qiang Yuan 8.18 Grain .177 caliber pellets was exceeded by the pellets in this test review. The average tested pellet weight was 8.53 Grains.
Although no specific head diameter is claimed explicitly for the Qiang Yuan 8.18 Grain .177 caliber pellets, there’s a label on the bottom of the box that included the numbers 4.50. The head diameter of the pellets tested by HAM averaged 4.52mm.
There were no damaged or malformed pellets in the HAM test sample.
Head diameter of the Qiang Yuan 8.18 Grain .177 caliber pellets was tightly controlled, with a minimum of 4.51 mm and a maximum of 4.53 mm. 60% of the “QY” pellets tested by HAM had this head diameter, with 36% at 4.52mm. Just 4% had a head diameter of 4.53 mm.
The variation between smallest and largest head diameters in the pellets tested by HAM was just 0.4%.
Weights of the Qiang Yuan 8.18 Grain .177 caliber pellets tested by HAM varied between 8.43 Grains and 8.60 Grains. So, none of the pellets actually weighed the claimed 8.18 Grains. The heaviest pellet thus weighed 2.0% more than the lightest tested.
The most common weight was 8.55 Grains, with 22 % of the tested pellets recording this weight on Hard Air Magazine’s incredibly-precise, laboratory-grade milligram balance.
The most common length for the Qiang Yuan 8.18 Grain .177 caliber pellets tested by HAM was 5.68mm. 24% of the tested pellets were of that length. The longest pellets – at 5.72 mm – were 1.9% longer than the shortest, which measured 5.61 mm.
The photograph below shows the amount of lead dust and dirt particles that was in the pack of QY pellets tested by HAM. This measured 0.45 Grains of dirt for the 200-pellet pack, equal to 0.23 Grains per 100 pellets.
This represents a low level of the dirt and dust that’s inevitable in lead airgun pellet manufacture.
As usual, HAM charted downrange performance for the Qiang Yuan 8.18 Grain .177 caliber pellets using the ChairGun ballistics program. We used a Ballistic Coefficient of 0.011, supplied by Predator International, the US distributors for QY pellets.
Muzzle Velocity averaged 907.3 FPS with the standard HAM test gun, the Beeman 1074. That equates to 11.74 Ft/Lbs of Muzzle Energy. Standard Deviation – the measure of shot-to-shot variability in Muzzle Velocity, was very low at just 3.97 FPS.
As Qiang Yuan 8.18 Grain .177 Caliber pellets are specifically designed for 10 Meter shooting, most shooters of these pellets will not be concerned with their performance at longer distances. However, Chairgun tells us that – if sighted-in at 35 yards – these QY pellets will shoot to a point of impact within plus or minus half an inch between 11 and 39 Yards.
Below is the data from which the above chart was calculated.

Qiang Yuan 8.18 Grain .177 Caliber pellets are specifically designed for precision 10 Meter shooting competition. So, it’s not really fair to evaluate them for hunting use. However, the accuracy and wound channel characteristics indicate that they could be used to good effect for very short range hunting of small animals or birds.
As a wadcutter, that’s flat-fronted, design, Qiang Yuan 8.18 Grain .177 Caliber pellets loose speed and energy very fast downrange. In fact Chairgun calculates that the retained energy will be just 11.0 Ft/Lbs at 15 Yards from the muzzle. That would be our recommendation for a maximum hunting range with these pellets.
However, the large – 10 mm – wound channel in the standard HAM soap test block would be an asset for hunting. Pellet head expansion was 16.5% in the soap block. The original head diameter of 4.52 mm had expanded to 5.27 mm in the target.
BUYING AND OWNING
Qiang Yuan 8.18 Grain .177 Caliber pellets are individually packaged in a push top plastic tray. As you would expect, this provides excellent resistance to damage from shipping. The wadcutter design gives very sharp, clean round holes in paper targets. Again as expected.
As a specialty product, Qiang Yuan 8.18 Grain .177 Caliber pellets are not widely available. However Pyramyd Air does carry them, so they are easily available for purchase by phone or online ordering.
Although these Qiang Yuan 8.18 Grain .177 caliber pellets are fairly clean to handle, all appropriate precautions associated with any lead product must still be taken in use.
