Today will look and sound like an accuracy test of the .177-caliber Air Venturi Avenge-X precharged pneumatic air rifle, but it isn’t. I will explain as we go. This is one of those “Learn how it works” days.
I mounted a UTG 4-16X44 Compact scope on the rifle. Initially the scope was in UTG rings that had been shimmed in the rear, but I couldn’t get the rifle sighted in with that because it shot too high. I removed the shim and got sighted in right away. There is another reason to like the new Avenge-X rifle — it doesn’t droop!
Filled the reservoir
The next job was to fill the reservoir to 4,350 psi/300 bar. For that I used the RovAir compressor that I’m also reporting on. You may remember that filling this rifle twice before has resulted in two failed burst disks, but last time I discovered that the onboard fill control gauge on the compressor was reading low when it was set to its high end. A setting of 4350 psi on the automatic shutoff resulted in a fill that went to 4,750 psi on the Avenge-X reservoir pressure gauge. I said then that I would set the auto shutoff at 4100 psi on the RovAir, but today before filling I backed it down to 4000 even. It filled the rifle and shut off with no problem this time and the Avenge-X pressure gauge read 4,350 psi — as close as I can read it.
The plan for today was to shoot groups from 25 yards with the Avenge-X. But like I said in Part 3, “I’m an old man and probably won’t live long enough to test all the possibilities this Avenge-X offers, so I’m not going to try. Instead I’m going to try to find an accurate pellet and see what sort of tune it likes — in .177.” Nice plan, but just as there were many possibilities with velocity, there are also possibilities when it comes to accuracy. I decided to pick one pellet and follow it all the way.
I shot 10-shot groups from 25 yards. The rifle was resting directly on a sandbag. I shot on high power and again on low power. I used the single-shot tray and I shot with the standard-capacity 10-shot rotary magazine. There is also a 20-shot high-capacity .177-caliber rotary magazine available for this rifle but Pyramyd Air was out of them when my rifle was sent, so I don’t have one to test. All the shots seen today were with the H&N Baracuda Match pellet with 4.50mm heads.
And now you learn why this is not an accuracy test. I normally test accuracy of any airgun in the morning when I’m fresh. On this day, however, I had numerous other tasks and didn’t get to shoot the rifle until the afternoon. That taught me an important lesson. Always test accuracy in the morning! I will explain as we go.
I shot the first target on high power and using the single-shot tray. After sighting in and discovering the scope shim had to be removed, then removing it and sighting in again, it was the middle of the afternoon before the first shot for accuracy could be fired. Shot one went where I wanted it (slightly to the left of the 10-dot on the target) and shot two went through the same hole. In fact the first four shots were so small I started thinking about using the gold dollar comparison coin for my groups.
Then shot five was a pinwheel (dead center in the bull) and my aim point was gone. After that I blew up and the first 10-shot group measures 0.309-inches/7.85mm between centers. I know that sounds like a good group and it really is, but from what I saw with the first four shots it’s at least twice the size it could be. With this Avenge-X there is really no reason to miss at 25 yards. I was having micro shakes that caused the pellet to wander about 0.125-inches/3.175mm from the desired aim point. Like most people I have these all the time, but this afternoon I couldn’t control them. Also the trigger was set too heavy for me and I had to fight it for the entire session.
After this group I adjusted the scope two clicks to the right
I switched to the rotary magazine for target two. The rifle was still set at high power. This time 10 shots went into 0.376-inches/9.55mm at 25 yards. The fourth shot from the mag landed lowest in the group and I remembered that in case the magazine has a bad chamber.
After this group I adjusted the scope two clicks to the right and two clicks down.
Now I switched to low power. Target three was shot from the single-shot tray, but the last two shots in this group were pulled to the right. Ten shots went into 0.426-inches at 25 yards.
The last target was shot on low power using the rotary magazine. Ten pellets made a 0.416-inch/10.57mm group. And the fourth shot hit lowest in the group, as it had the previous time the magazine was used.
Where we are
As I said, today was not an accuracy test because I was too jittery to do my best. This rifle is clearly (to me) very accurate. Now I need to make it do its best for you.
The single shot tray is slightly more accurate than the rotary magazine, but only because the fourth shot from the magazine lands low. I find the single shot tray quite a bit more fiddly to load. Therefore I think going forward I will shoot from the magazine.
The Baracuda Match with 4.50mm head seems to be an accurate pellet in this .177-caliber Avenge-X. High and low power don’t seem to make much difference in accuracy at 25 yards.
Stage two of the trigger definitely needs to be lighter for me to do my best. I need to do that before the next test.
So far I am very impressed with the Air Venturi Avenge-X precharged pneumatic. It’s doing everything I want and more. Now I need to get me up to speed, so I can test the rifle at its best.
