If you've ever spent a Saturday afternoon plinking tin cans in the backyard, you've probably handled a 66 powermaster or something very similar to it. It's one of those classic air rifles that seems to bridge the gap between "just a toy" and a serious piece of hardware. Whether you've had one tucked away in your garage for a decade or you just picked up a refurbished model, there is something undeniably satisfying about the multi-pump action and the distinct "pop" it makes when you finally pull the trigger.
It isn't the most powerful airgun on the market, and it certainly isn't the most expensive, but that's exactly why people love it. It's accessible. You don't need a scuba tank for compressed air or a high-end compressor to get it running. You just need your own two arms and a bit of patience.
Why This Specific Model Stands Out
The 66 powermaster, often recognized under the Daisy PowerLine brand, has a bit of a legendary status among hobbyists. It's a multi-pump pneumatic, which means you're the engine. The more you pump, the more pressure you build, and the faster that pellet flies.
What makes it different from some of the heavier, wood-stocked rifles is its weight. It's incredibly light. For a younger shooter or someone who just doesn't want to lug around a seven-pound rifle all day, the 66 is a dream. It's mostly synthetic, which some purists might complain about, but it makes the gun incredibly durable. You don't have to worry as much about a little rain or a scratch on the stock when you're trekking through the woods.
The versatility is another big selling point. It's a dual-ammo shooter. You can load it up with a reservoir of BBs for high-volume fun, or you can single-load pellets when you actually want to hit something small at twenty yards. Having that choice without needing to switch guns is a huge plus.
Understanding the Multi-Pump Mechanic
One thing people often get wrong with the 66 powermaster is the pumping. There's a sweet spot. Usually, the manual says you can go up to ten pumps, but honestly, for most target practice at close range, three or four is plenty. It saves your arms from getting tired, and it's a lot quieter.
If you're trying to deal with some small pests or you're shooting at longer distances, sure, crank it up to ten. But you'll notice that after the seventh or eighth pump, it gets significantly harder to close that lever. That's the air pressure fighting back. A little tip for longevity: never leave the gun fully pumped for long periods. It puts a lot of stress on the O-rings and seals. If you're done shooting, fire off a "blank" shot (without a projectile, if the manual allows, or just a safe clearing shot) to let the air out.
The pump handle itself is usually tucked into the forearm of the stock. It's designed to be ergonomic, but after fifty or sixty shots, you're definitely going to feel it in your triceps. It's a workout and a hobby all rolled into one.
Accuracy and the Rifled Barrel
A lot of cheaper air rifles have smoothbore barrels, which are fine for BBs but terrible for pellets. The 66 powermaster features a rifled barrel. This is a game-changer if you're looking for accuracy. The rifling puts a spin on the pellet, stabilizing it in flight.
If you're using BBs, keep in mind that they are slightly smaller than the bore and they don't engage the rifling. They kind of bounce their way down the barrel. That's fine for hitting a soda can at ten feet, but if you want to group your shots tightly, you've got to use lead pellets.
I've found that mid-weight wadcutter pellets work wonders in this rifle. They cut clean holes in paper targets and they seem to be the most consistent. Since the 66 doesn't have the insane velocity of a high-end break-barrel, you don't really need those heavy "magnum" pellets. Stick to the basics, and you'll be surprised at how accurate this little rifle can be.
Maintaining Your Rifle for the Long Haul
You'd be surprised how many people treat their 66 powermaster like it's indestructible. While it's tough, it does need some love. The biggest enemy of any pneumatic airgun is dry seals. If those internal O-rings dry out, the gun won't hold air, and your shots will start dropping lower and lower until the gun won't fire at all.
Every few hundred shots, put a drop of Pellgunoil (or a similar non-detergent, silicone-based oil) on the pump pivot points and the air intake hole. Avoid using regular WD-40 or motor oil; those can actually damage the rubber seals over time. A little bit of the right oil goes a long way.
Also, keep the barrel clean. Even though it's "just an airgun," lead buildup and dust can affect your grouping. A quick pull-through with a cleaning patch every now and then keeps everything shiny and consistent.
The Fun Factor of Backyard Plinking
Let's be real: most people buy the 66 powermaster because it's fun. There is a certain nostalgia to the sound of the pump and the click of the safety. It brings back memories of summer vacations and competitive shooting matches with siblings or friends.
It's also a fantastic tool for teaching. If you're introducing someone new to shooting sports, the 66 is much less intimidating than a firearm. It's quiet, it has zero recoil, and it forces the shooter to slow down. Because you have to pump it every time, you tend to make every shot count. You're not just spray-and-praying like you might with a semi-auto CO2 pistol.
There's also the "tinkering" aspect. Because these guns have been around so long, there's a whole community of people who modify them. People change out the sights, add scopes, or even work on the triggers to make them smoother. It's a gateway drug into the world of airgunning.
Pellets vs. BBs: Which Should You Use?
This is the age-old debate for 66 powermaster owners. The gun has a BB reservoir that can hold quite a few rounds, which is great for "active" shooting. You just shake it, cock it, and you're ready to go. But BBs are made of steel, and they are harder than the rifled barrel. Over years and years of heavy use, BBs can eventually wear down that rifling.
If you care about long-term precision, I'd suggest using pellets 90% of the time. Pellets are made of soft lead (or lead-free alloys) that won't hurt the barrel. Plus, pellets are much safer regarding ricochets. BBs tend to bounce off hard surfaces like crazy. If you're shooting at a wooden fence or a metal target, a BB might come flying right back at you. Pellets usually just flatten out on impact.
That said, if you're just having a blast at a pile of dirt or some plastic bottles, throwing some BBs in the reservoir is the easiest way to keep the fun going without constantly reaching for a pellet tin.
Is It Still Relevant Today?
With all the high-tech PCP (Pre-Charged Pneumatic) rifles and gas-piston break-barrels out there, you might wonder if the 66 powermaster is outdated. In my opinion, it's more relevant than ever.
In a world where everything needs a battery or a specialized pump, the simplicity of a multi-pump rifle is refreshing. It's self-contained. If you have a tin of pellets and your rifle, you can shoot all day. There's no "running out of air" or "dead batteries."
It's also incredibly affordable. You can usually find these at a price point that makes them an easy "impulse buy" or a great gift. It doesn't feel like a massive investment, yet it provides years of entertainment. It's the kind of gun that gets passed down from an older brother to a younger sister, or sits in the corner of a tool shed ready for whenever a stray soda can needs to be dealt with.
Final Thoughts on the Classic
At the end of the day, the 66 powermaster represents a specific kind of freedom. It's the freedom to head out into the yard and practice your marksmanship without a lot of fuss. It's not about being a professional sniper; it's about the satisfaction of a well-placed shot and the rhythmic process of pumping, loading, and aiming.
It might not have a walnut stock or a 12-pound match trigger, but it has heart. If you take care of it, it'll take care of you, providing thousands of rounds of cheap, reliable fun. So, if you've got one gathering dust, go grab some oil, a tin of pellets, and see if you can still hit that target. Chances are, it'll still put a smile on your face.
