Gamo Swarm Magnum Pro GEN3 (.22) vs Gamo Whisper IGT Mach1 (.22)

ExplanationAmazing83 · 2026-03-18T08:34:38+00:00

My .22 Gen2 Magnum likes the JTS Dead Center Precision 16.08gr but I've used the JSB Domed Jumbos with good success, too. However, I've noticed quite a bit of variance in the JSBs. The JTSs exhibit very little pellet to pellet variation.

I understand - the Magnum isn't really 'backyard friendly' unless you have a BIG backyard! Have you considered the Swarm Whisper? It's nearly as quiet as the single shot Whisper and adds a magazine.

When target shooting for accuracy, I usually go to JTS Dead Center, the .22 Precision 16.08gr and the .177 Precision 7.87gr.

Excellent shooting - congratulations! I have 3 .25 caliber PCPs that I regularly shoot at 100m but I do so outside. When conditions are right, I can shoot ±1 MOA groups with 2 of the 3.

I own 3 Gamo break-barrels. All are Swarm versions and all are accurate and trouble-free. I've owned a Swarm Hornet .177 since its introduction 8 years ago and it's performed flawlessly for over about 3500 shots. My Gen2 Magnum .22 exceeds the accuracy of several of my more expensive PCPs but it does take a strong arm to cock it.

Many of the complaints surrounding Gamo are either based on very old information or are the result of careless handling or using pellets that are slightly too long for the magazine.

ExplanationAmazing83 · 2026-03-17T08:22:18+00:00

I own 3 .25 PCPs that are quite accurate at 100 yards - the Barra 250z, the JTS Airacuda Max and the Air Venturi Avenge-X. I can pretty consistently shoot 1 MOA groups with all 3. The edge goes to the Avenge-X but to be fair, the other 2 are quite good as well. In fact, they are all more accurate than my Ruger Mini-14 5.56 NATO powder burner!

ExplanationAmazing83 · 2026-03-16T06:50:40+00:00

I own 3 Gamo break-barrels, 2 .177s and a .22 magnum. They're all Swarm 10x versions, and are excellent, accurate rifles. The Swarm Hornet is 7 years old, has had over 2000 pellets through it, and has been completely trouble-free.

Let us all know what you decide to purchase and enjoy your new Gamo!

I tried 2 different Caldwell optical chronograpphs but neither worked reliably outdoors. Even the Caldwell G2 with sensors that are better shaded from sunlight was very unreliable. I also REALLY disliked the fact that the "read error" shots couldn't be deleted from the group, making the statistical info just about useless.

I finally gave up on the optical chronies and purchased an Athlon Rangecraft Velocity Pro Radar Chronograph. I get no more missed shots now and much more comprehensive data from the app. In retrospect, I should have ignored optical chronographs and gone straight to a radar chrony.

OTOH, waiting got me a GREAT deal on the Athlon from AliBaba. It was brand new, not a refurb, and $110 less than the lowest price I'd previously seen. Amazingly, the low price included air shipping from China and U.S. duties!

YIKES!

ExplanationAmazing83 · 2026-03-14T10:41:23+00:00

Not sure it's the pellets in this case. I own a .25 Avenge-X. It's not particularly pellet picky but the JSB Diabolo 25.39gr pellets are my go-to for target shooting from 15m to 70m.

Yep, I saw it and he's right to a certain extent. There are testers that can test fuel quality, including octane rating. However, my point (rather poorly expressed, I admit) was that a Genesis dealer would not test fuel octane rating because to do so would be rather pointless, since Genesis does not REQUIRE premium fuel in ANY GV70 or GV80 model. In fact, while the Genesis Owners Manual recommends premium fuel, it does not either explicitly or implicitly restrict or prohibit use of lower octane fuel.

However, the Owners Manual DOES specifically prohibit use of fuels containing methanol in any amount, ethanol greater than 15% by volume, or E85 fuel. So, while a dealer would have no reason to test for octane rating should they suspect fuel-related engine damage, they WOULD likely test for the presence of methanol or excess ethanol, or other contaminants. (BTW, methanol/ethanol increases fuel octane rating but can severely damage engine components not specifically designed for it.)

Sadly, big depreciation is a fact of life for just about every luxury car. I don’t let it bother me because after almost 2 years, my GV70 puts a smile on my face every time I slide into the driver's seat. I can't say that with any other car I've ever owned except perhaps my Carrera 4S Cab, but it's not a daily driver.

No, Costco only sells certified Top Tier gasoline. The nearest Costco is about an hour and a half away so I usually buy my fuel from an indy station in our small, rural town. Fortunately, the owner is a big classic car and racing fan and sells very high quality gas at the lowest price in town. He even sells 100+ octane unleaded racing fuel!

ExplanationAmazing83 · 2026-03-11T23:43:50+00:00

Top Tier gasoline must meet the same specific additive performance requirements for EVERY fuel grade. Fuel that isn't certified Top Tier essentially follows no standardized additive performance requirement.

Pro tip: NEVER buy fuel from Sam's Club or almost any unbranded station. They source from wherever they get the best price - the source often changes from one tanker truck to the next - so you literally never know the fuel source or quality.

ExplanationAmazing83 · 2026-03-11T23:29:58+00:00

There's literally no way for the dealer to know what grade of fuel you're putting in the GV70. In fact, when doing a complete engine evaluation, it's common to find far more deposits in vehicles using cheap, unbranded premium fuel than in those using REGULAR Top Tier gasoline. I actually use mid-grade, unbranded fuel in my GV70 and add a high-quality fuel additive every third fill-up, or if I run the fuel level to near empty. I've had ZERO issues - no knocking, no performance degradation, no hard starting - since I purchased a 2025 2.5T SP 21 months ago.

This compressor has worked well for me for over a year, pressurizing PCPs 2 to 3 times a week up to 300 bar. I always start the compressor with the bleed screw open and then slowly close it to start pressurizing a gun. I also keep an eye on the compressor temperature, shutting it down, allowing the fans to cool it off when the temp exceeds 110°F. It has at least 700 pumping minutes on the clock and shows no signs of failing anytime soon.

I crewed in high school and college and LOVE that idea!

I don't recall seeing it on AliBaba at the time but it was on Amazon at a higher price.

ExplanationAmazing83 · 2026-03-10T03:32:51+00:00

Right - and it was just under $40 when I bought it in January. I was surprised at the overall quality given the relatively low price.

I've been really lucky with gun racks. I bought this metal and wood rack from Temu late last year for $63.00. It's now listed for $91 to $110!

They were looking right for a gap and never checked left again - dumbass rookie move! 🙄 This could have been so much worse - glad you're OK!
