- So — how is it?
Today we back up to 25 yards to test the accuracy of the .22-caliber Benjamin Gunnar. This rifle has been interesting from the start and we now have a good handle on it’s performance.
It’s been a long time since I last shot the Gunnar, so I read the previous reports to see where things were. I remembered the part about the DonnyFL Ronin silencer not aligning with the barrel, causing me to put pellets into the jamb of the door leading into my garage. Even if I didn’t read the reports I had the pellet holes to remind me.
I forgot how quiet the Gunnar is. But in Part 2 I found that on full power it was only 91.9 dB. I also discovered that in the center of the power adjustment range the rifle is still getting 30+ foot-pounds, and there are as many as 60 shots per 3,000 psi fill, which is performance you can take to the bank. The 3,000 psi fill is a wise step because it doesn’t drain your air tanks fast like a 300-bar (4,351 psi) fill does.
I also enjoyed reading that the 12-shot rotary magazine is straightforward to load. It doesn’t require pellets to be put in backwards or other nonsense. When I finished reading I was ready to test.
I shot the Gunnar from 25 yards off a sandbag rest with the rifle resting directly on the bag. I extended the buttstock as far out as it goes and the scope was in perfect alignment with my eye. The trigger is quite good, as I have reported in the past.
The rotary magazine holds 12 rounds and as I said it is straightforward to load. For the first group I loaded all 12 chambers because I would use the first two to sight in and then adjust the scope to shoot the group. After that I loaded 10 rounds of each pellet. All the groups shown today were 10-shot groups.
First group — JSB Exact Jumbo Heavy
First to be tested were JSB Jumbo Heavy pellets. They were the most accurate at 10 meters. The first shot landed two inches high, as the rifle was sighted in at 10 meters. I cranked in a lot of down elevation and shot two hit an inch low and an inch to the left of the aim point. I adjusted the scope up and to the right and the next shot, which was the first in the 10-shot group, was a pinwheel that took out the center dot in the bull of a new target. Oh, boy! From this point on I had to overlay the reticle lines over the target ring numbers to center the shot. With that I put the first four shots into a tiny hole that would have been smaller than one-tenth inch between centers. Then the group started to enlarge.
The final 10-shot group measures 0.357-inches between centers. Not bad for 25 yards when I had to guess where the center of the target was! Because of that I adjusted the elevation of the scope 6 clicks down.
We are on a roll. The next pellet tested was the 18-grain H&N Baracuda. Ten of them made a 0.517-inch group at 25 yards. Once more I almost blew the aim point away with the third shot.
Baracuda Match with 5.53mm head
The next pellet I tested was the H&N Baracuda Match with 5.53mm heads. Ten of them went into 0.582-inches at 10 meters, with nine of them in 0.385-inches at 25 yards. Shot seven is the one that dropped low and to the right and I don’t know what happened. It wasn’t a called pull. And as before I blew the aim point away and had to guess where the center of the target was.
The Gunnar put ten Baracuda Match with 5.53mm heads into 0.582-inches at 25 yards, with nine in 0.385-inches. I have no idea why the one shot hit low and to the right, but it wasn’t a called bad shot.
It dawned on me that I had not tried Crosman Premier pellets in the Gunnar. Yes, we know that Crosman probably didn’t make this rifle in the U.S. But it is still one of their airguns.
However, I also discovered in the Part 3 test that the Gunnar likes medium-to-heavyweight pellets best. That suggests the Premiers that weigh 14.3 grains will probably not group as well as the heavier pellets. Yet they did. I blew out the aim point early in the test, of course, and guessed where the aim point was after that.
Ten Premiers went into 0.505-inches at 25 yards, so it wasn’t that bad. It looks larger than the others, but when I measured it several times it really wasn’t.
So — how is it?
The Gunnar is pulling its weight. Of course we need a 50-yard test to know for certain, but as a hunting air rifle, it looks like a winner. Lots of shots on a 3,000 psi fill, accuracy, quiet report, nice magazine and decent trigger. There is a lot to like.
