Review of Gamo Combo Pack .177 cal. Performance Pellets

November 23, 2011

In November of 2011, I received a ten dollar gift card in the mail from a local sporting good chain. As is the case with many sporting goods stores today, they ceased selling firearms and ammunition and now concentrate on selling running shoes and clothing. Looking for something not much over 10 dollars that I could use, I settled on a combination pack of 1000 Gamo pellets for about 12 dollars. Since I had never used that brand before, I decided to compare their accuracy to the lead pellets that I had currently been using.

Gamo pellet tins

The Performance Pack consisted of four steel tins each containing a different style of lead air gun pellet.

General Observations

Manufactured in Spain, Gamo Lead pellets appear to be harder than most of the other brands of lead airgun pellets that I have used. The Master point and Magnum styles seem particularly hard. Also, the seams and extruded lead left by the swaging die during manufacture were particularly evident on the "Magnum" pellets.

With my old Crosman 1377, I usually use Crosman or RWS wad cutter pellets and find 4 pumps sufficient to propel the pellet into a steel pellet trap 15 feet away with sufficient accuracy to create dime size or smaller groups. Accuracy was very poor when using only 4 pumps with the Gamo pointed pellets. When fired from a Crosman Model 1377 pistol, I found that a velocity in excess of 300 feet per second was required to flare the skirt enough for the pellets to group properly even at the short distance of 15 feet.

Pumping 6 - 8 times reduceed group size to about the size of a quarter but the Crosman and RWS wad cutter pellets that I usually use still are more accurate.

I next tried Gamo pellets in my spring-piston air rifle, a Winchester Daisy 800x with a 4 power scope along with RWS wad cutter pellets for comparison.

Firing two, five round groups of each pellet to a distance of 25 yards from a sand bag, I got the following results. I should disclose that this was at an outdoor range and that there was a significant wind that day.

For RWS - Pellet Weight 8.15 grain average group size was 1.06 inches
Gamo Match - Pellet weight 7.5 grain average group size was 1.125 inches
Hunter - 7.6 grain average group size was 1.50 inches
Masterpoint 7.6 grain average group size was 1.50 inches
Magnum - 7.6 grain Average group size was 2.40 inches

In general, I found that the accuracy of the Gamo Match and Hunter pellets were pretty good, comparable to other major brands. From an accuracy standpoint the Masterpoint pellets were acceptable but the Gamo Magnum pellets were a bit of a disappointment.

The variation of group size for each type of pellet was 1/4 inch or less.
