Frequently Asked Questions

How do .22 LR, .17 HMR, and .22 WMR compare in penetration tests?

.17 HMR generally excels in penetrating harder materials like lumber and steel. The .22 WMR also shows strong penetration, especially with hollow-point rounds in ballistic gel. The .22 LR typically demonstrates the least penetration across most tested mediums.

Which rimfire caliber is best for penetrating steel plates?

Both the .17 HMR and .22 WMR are significantly more effective at penetrating mild steel than the .22 LR. The .17 HMR created a slightly deeper crater in 3/16 inch steel compared to the .22 WMR in this test.

What was the performance of .22 WMR hollow points in ballistic gel?

The .22 WMR Hollow Point ammunition demonstrated excellent performance in ballistic gel, achieving a penetration depth of 12.5 inches and creating a substantial wound cavity, indicating effective energy transfer.

Did any rimfire caliber penetrate 6 inches of sand?

No, in the conducted tests, none of the rimfire cartridges (.22 LR, .17 HMR, or .22 WMR) were able to penetrate the full 6 inches of solid sand, resulting in a draw for that particular test medium.
