Paco's Acu'Rzr Tool for Shaping Lead Rimfire Bullets

Here is an interesting tool that lets rimfire shooters re-shape and uniform the tips of their 22 rimfire lead bullets. Paco Kelly’s Acu’Rzr comes in two versions, the “Phase III Nasti-Nose” and the “Phase IV Baby Scorp’n”. The Phase III tool produces a deep-dished hollowpoint (like an ash-tray) that opens quickly and efficiently. There is also a Phase III insert that creates a flatter, open dish HP for target shooting. The Phase IV Scorpion tool creates a deep hollow point with a central post in the middle. The internal post in the middle helps achieve deeper penetration in game. The designer claims that ammo modified with either tool is more accurate because the bullet diameter “comes out the same every time”.

Why re-shape lead rimfire bullets? The first reason is accuracy. The tool’s designer, Paco Kelly, claims you can improve the accuracy of budget-priced ammo by using the dish nose rod with the Phase III tool: “The dish nose forming rod is for accuracy and paper targets. It makes very sharp and clean cut holes in paper. And the consistency of the [re-shaped] bullet diameter pulls the group together.”

The main reason to use Paco Acu’Rzr tools is to improve perfomance on small game such as squirrels, prairie dogs, and jack-rabbits. Kelly says: “Unlike most commercial 22 rimfire ammo with small holes and negligible HP expansion, the Nasti-Nose will open even with standard velocity ammo. Yet it will NOT explode on contact like the hyper-velocity ammo. For small eating game, such as squirrels, the Hyper ammo is too much and the medium-velocity, hollow-pointed commercial ammo often fails to open. But not so with the Nasti-Nose.” The idea, Kelly suggests, is that you get reliable expansion with medium-velocity ammo, without destroying the game the way more expensive, hyper-velocity ammo does.

The Phase III tool costs $65.00, while the Phase IV tool costs $75.00. Both tools can be customized for target rifles or European chambers. To order, contact Paco Kelly, P.O. Box 1170, Cortaro, AZ 85652 or use this ORDER FORM.

EDITOR’s NOTE: Do NOT use this tool with premium-grade rimfire target ammo. It won’t help. Use it with the cheaper bulk-pack ammo. Also, we have not tested the reformed ammo on live targets, so you have to draw your own conclusions as to its benefits on small critters.
