H&N Excite Prometheus Pistol Pellets, .177 Cal, 4.5 Grains, Wadcutter, Lead-Free, 250ct

Very powerful for lightweight lead free pellets. They work great in my co2 pistol also in my nitro piston crosman.

The price is high for 250, and you should sell larger packs.l

The plastic is very durable but about 30% of the time the metal round seperates from the plastic on impact even in my co2 pistol.

Kudos to the German engineer(s) for thinking outside the Diablo paradigm! These may be the next generation pellets. I would like to chat and share design ideas with the engineer(s) at Excite.

Molding an embedding barb(s) in the metallic body stem to help retain the sabot upon discharge

I had to change from Crossman's SSPs because they are no longer available in .177. That made choosing Excite's design a no-brainer. I tested them using my Beretta PX-4 Storm, a CO2 pistol. With the SSPs, a full CO2 charge will send 96 rounds effectively to a target at 10 meters. With the Excites, the first 48 flew down range brilliantly and with a high velocity crack. However, around round #80 the gun seemed to be out of power, rounds were not exiting the barrel reliably and strings of polypropylene ribbons were floating from the barrel when and if a round did exit.
Upon routine cleaning I found the "problem" -- 4 rounds had stuck or seized in the barrel. Two of the rounds were complete sabot-metallic, the other 2 were simply the sabot. I am assuming here that these rounds require full CO2 pressure to be effective and reliable. As the pressure drops due to consumption, the metallic tends to separate from the sabot while inside the barrel. NOT RECOMMENDED, yet. Pics available.

The extra long tube-shaped body is easy to hold for loading. It's not that difficult to tell by feel which end of the pellet is the tail end, as the tail has a nice sharp edge while the head feels rounded. So low-light loading would be excellent in combination with the easy to hold body of these things. Contents of tin show some very clean looking pellets. Lid of tin is sealed with tape. The plastic bodies make for a quiet pellet when carried in bulk, though this would best be done in a soft pouch and not in the tin

Listed weight is not what I found. I have a powder balance with: 6, 5 ,4 ,3 ,2 ,1 , 0.5, and three 0.125 grain weights. So just a tiny bit of estimating was required, but it looks to me that these pellets are more like 5.6 grains +-0.01 out of the ten I tested The forward half of the plastic section ought to have a longer band, in order to grab the rifling more The plastic would be much 'greener' if it could be claimed to be the biodegradable type. And I know there is airgun capable bio-plastics, just look at the airsoft offerings! Nice that I'm not polluting the environment with little pieces of lead, but what about all these little bits of plastic? - to the good, the plastic is a dark color, so it doesn't stand out as much like an airsoft round does My overall impression is that these are better suited for hunting, and so the head shape is completely wrong. I would like to see these with either the Terminator, or Red Scorpion running part of the body through the head

Pellet weight is much heavier than the Pyramydair specs claim. Listed here as 4.5 grains, I measured 5.6

Something about these pellets make them much louder when hitting cardboard as compared to a few other lead-free pellets. Possibly the plastic tube is acting like a resonator?

Some of the holes in my paper target looked suspiciously large, like the pellet might have been tumbling?

The Winchester Round Nose MVP for example, weighs 4.4 grains on my balance +-0.1, and seems much more accurate out of my stock barreled P17

Gives better velocity and adequate accuracy from Beeman P17. Being lead free, it is safer for indoor shooting.

Nothing

I won't use them in my springers because I suspect these pellets could damage them by not providing enough resistance to keep the piston from bashing the cylinder head.

Lead Free and Accurate

These are one of the better lead free .177 pellets I have tried so far at 5-15 Meters. I have tried these in my Beeman P17, Walther CP99, and SIG MPX and the pellets are accurate in all these guns. These are all low powered guns too so I am not sure how they will work in a Springer, NP, or PCP gun. Grouping is consistent and don't tend to fly all over the place like most lighter lead free pellets in these guns.

The super hard tip made these pellets very good at penetrating solid objects like steel sheet metal, comparable to gamo "lethal" pellets but at a much lower price. The size was perfect for rotary pistol/rifle magazines.

The plastic sabot needs to be made with a harder material like the gamo lethal pellets so it does not leave plastic shavings in the air gun barrel.

These pellets will dirty your air gun barrel fast! The plastic sabot is so soft that when it catches an air guns rifling it shaves away the plastic leaving long thin strands of it throughout the barrel. After 20 shots, I ran a nylon barrel brush through my rifle and pulled out what looked like a clump of black hair from a bathtub drain. This problem was also present with the Prometheus domed version of these pellets as well as the Crosman fast flight penetrators (which left red "hair").

These are a substitute for BBs and pellets. Faster than BBs and less accurate than lead pellets, but, I like them because I can keep areas like patios lead free. I will buy more because in plinking they are fast enough to give an extra amount of range where BBs are not accurate. That means maybe 10 to 20 feet.

They will bounce, recoil, off hard objects, but no worse than BBs. Maybe softer sabots?

These, like air soft pellets are for plinking, so don't consider real tight groups.

Consistency. Very clean.

Maybe the price? They are a tad spendy.

I tried these in four of my most accurate guns at 25 ft. against my go-to short range pellet, RWS Diabolo Basic. In my Daisy 753 and IZH 61, the POI changed a bit, but the accuracy was outstanding. Interestingly, my Tau 200 did not like these at all, 3/4" groups at 25'. This is a one-hole gun with Basics. Lastly, I tried them in my highly modified Crosman 24" barreled 1389. They performed well enough in this gun. I have no input at longer distances or higher velocities, but if you are looking for a lead-free pellet for low-velocity guns, these are worth a try. As a plus, they cut very clean holes in target paper.
Would I switch to these over the proven Basics? Probably not, but they are good enough if you feel strongly about lead alternatives.

Uniform shape thus easy to load. No lead and properly accurate.

Perhaps an increase of weight to 7 grains for more energy retention.

Be mindful of potential ricochets as they will not absorb the energy as typical lead pellets will.
