Frequently Asked Questions

How do .22LR, .17 HMR, and .22 WMR compare in penetration against concrete blocks?

.22LR required multiple shots to penetrate a concrete block wall. Both .17 HMR and .22 WMR demonstrated superior penetration, with each caliber successfully penetrating the first wall in two shots, indicating higher energy transfer and effectiveness against such materials.

What rifles and ammunition were used in the concrete block penetration test?

The test utilized a Ruger 10/22 for .22LR with Aguila 40gr ammo, a Savage 93R17 for .17 HMR with CCI 20gr Gamepoint ammo, and a Rossi RS22M for .22 WMR with CCI 40gr Maxi-Mag ammo. All rifles had barrels around 21 inches, except the 10/22 at 18 inches.

Which rimfire caliber is most effective for penetrating concrete cinder blocks?

Based on the test, both .17 HMR and .22 WMR proved more effective than .22LR for penetrating concrete cinder blocks. They required fewer shots and caused more significant material displacement, suggesting higher energy retention and impact force.

What are the key differences in velocity and grain weight for the tested rimfire ammunition?

.22LR (Aguila) was 40gr at 1255 fps, .17 HMR (CCI) was 20gr at 2375 fps, and .22 WMR (CCI) was 40gr at 1875 fps. The .17 HMR had the highest velocity, while .22LR and .22 WMR shared the same grain weight but differed in velocity.
