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" .
