RWS HyperMAX .177 Cal, 5.2 Grains, Pointed, Lead-Free, 100ct

Its good to have a harder metal than lead for penetration, especially if you are shooting an air gun with muzzle velocity below around 800 fps.

However, these are too low mass ( grains) and too pricey to be a good choice for my replica pistols

Mass helps in accuracy, carry and muzzle energy

Hyper is right: hyper speed, hyper consistent, hyper consistency. Trajectory is hyper flat with hyper accuracy shot from my modified 1377 at all power levels and distances. They have jewelry quality aesthetics. Superb lead-free pellet!

Cost. The high quality is easily observable, so I am totally sure the manufacturer is charging a fair price. Even so, I can't afford to shoot a lot of these at $0.10/pellet.

Using my FX Pocket Chronograph, I measured ~850FPS avg (>8FPE) at 65F out of my modified 1377 with a LW 14.6" match barrel, an upgraded valve, port, and spring and an ungodly quantity of pumps. For comparison, the Predator GTO 6.79gr achieved ~700 FPS avg (>7FPE) at the same #of pumps. The HyperMax simply rip through hard targets like nothing else I've seen! It frightens me to think what they would do in a high powered PCP... If you want to splurge and try out some excellent pellets, go for it, and invest the $10.00!

These pellets are all very consistent in size with respect to each other , they're like match grade in my opinion. And to be individually placed in little pockets , preventing damage to each other is a plus.

I own a GAMO Quiet Cat break barrel rifle , and in my case these pellets are a bit loose. They even tend to slide down the barrel before I even pull the trigger. Maybe the manufacturer honed the barrel out 0.0005 in. too much ??

For those of us that reside in California , I'm glad these pellets are "lead free" .

Very lite, good shape.

Small count for the price.

Accurate!

Very clean, nice, I really like the packaging, no deformed pellets, very sharp. I like how pellets are easy to grab and that you can stack multiple packages of them.

Mostly price and pellet count

I fired these in my modified Crosman 1377. I get very good accuracy with these and very good penetration. In my penetration tests into blocks of soap these had similar performance as crosman hollow points. These will work for short range small game. I shot a rat at 15 yards through its nose and out the back of its head.

Great ammo to see what FPS your air gun can really do.

Heavier weight choices

This is not for everyday shooting . They are loud. If your rifle or pistol does 900 fps on leads. They will go super sonic . Very fast, very loud. But if you have friends that say air is a joke. Touch one of these off and they will change mind.

These pellets are a bit pricey, but their accuracy in my Crosman Vigilante (CO2 pistol) makes up for that. From a bench rest I shot Crosman Premier Match 7.9grains, and Crosman Penetrators through my Vigilante as well for comparison sake and the HyperMAX grouped the best. If you like to target shoot tight groups and you can afford them these are great pellets. I like the packaging as well.

They are the most expensive lead free pellets out there, I'd like to see the price come down a bit, but not at the expense of quality.

Judging from the comments by air rifle shooters about sound barrier crack, etc. these pellets probably work best in low power guns (600fps velocity) like CO2 pistols/rifles, within a thirty foot range. Alternatively, I found the RWS MeisterKugeln 7.0grain lead pellets (@ 03 cents each) are just as accurate as the HyperMAX alloy pellets( @ 10 cents each). I've tried a variety of pellets in my pistols, and RWS has my vote hands down, with JSB in a close second place.

I find these pellets are perfect for use in my Walther CP88 (4" and 6" barrels) and my Baretta 92FS. Even though Umarex does not advise using pointed pellets in these two handguns, I find the length of the HyperMax pellets is a perfect fit into the alloy magazines. Never a jam. Plus, with CO2 pistols, which are not extremely powerful, the penetration from these pellets is great. In tests I find HyperMaxx pellets, used in these handguns, can penetrate steel soup cans and thick plastic containers where dome pellets cannot. The packaging, as others have said, is also wonderful and protective.

A bit high priced, in my opinion.

Be cautious as some .177 pistols do not like these pellets. My Beeman P3 and P17 pistols do not work well with the Hypermax. They jam every time I attempted to use them. Also, these pellets do not work particularly well with powerful .177 rifles.

I like these a lot and will continue to buy them.

Price.

Try them.

Packaging is outstanding. all hold there shape perfectly. The alloy they are made of is extremely hard. A perfect pellet for my Gamo MP-9 and P-25 Co2. Accurate with lower velocities. However when fired through my Gamo Whisper Fusion Elite with 1300 fps it sounded really cool but lost accuracy at such a high speed. As I expected

I would offer a stacked package with 200 count but other than that I wouldn't change a thing. Perfect for anything less than 850fps

I would not recommend this for a air gun with a velocity greater than 850fps
