Kel-Tec PMR - 30 Comparison

Published on February 10, 2012
Duration: 21:57

This guide details a comparative ballistics test between the .22 Long Rifle and .22 Magnum calibers, using firearms like the Smith & Wesson Model 41 and Kel-Tec PMR-30. It outlines steps for testing impact on various targets, from water containers to steel plates, to demonstrate the significant differences in energy transfer and penetration. The assessment highlights the superior performance of the .22 Magnum in terms of hydrostatic shock and hard target engagement, as presented by an experienced firearms instructor.

Quick Summary

The .22 Magnum cartridge demonstrates superior ballistics compared to the .22 Long Rifle, offering over 600 FPS higher velocity and significantly more energy transfer. This results in more explosive impacts on soft targets and deeper penetration through hard materials like metal and concrete, as shown in tests with firearms like the Kel-Tec PMR-30 and Smith & Wesson Model 41.

Frequently Asked Questions

What are the key differences in ballistics between .22 Magnum and .22 Long Rifle?

The .22 Magnum, exemplified by CCI Maxi-Mag at 1,875 FPS, significantly outperforms the .22 Long Rifle (CCI Mini-Mag at 1,235 FPS) in velocity and energy transfer. This results in more explosive impacts on soft targets and deeper penetration on harder materials like ammo cans and cinder blocks.

How does the Kel-Tec PMR-30 compare to the Smith & Wesson Model 41 in terms of physical characteristics?

The Kel-Tec PMR-30 is notably lightweight at 13.6 oz (unloaded) with a 4.3-inch barrel and a 30-round capacity. In contrast, the Smith & Wesson Model 41 is heavier at 44 oz, features a 7-inch barrel, and is chambered in .22 LR, often seen with traditional wood grips.

What kind of targets were used to demonstrate the performance difference between .22 Magnum and .22 LR?

The comparison utilized a variety of targets, including water-filled containers and 2-liter bottles to show hydrostatic shock, metal ammo cans and cinder blocks for penetration tests, and swinging steel plates along with cast iron to evaluate kinetic energy transfer.

What are some notable features or potential quirks of the Kel-Tec PMR-30 mentioned in the video?

The PMR-30 is praised for its light weight, high capacity, and good fiber optic sights. A personal quirk noted by the reviewer is that his grip sometimes inadvertently releases the magazine during safety engagement, suggesting users be mindful of their grip technique.
