Winchester Super X 40gr .22wmr VS Winchester Dyna Point 45gr .22wmr Ballistic Gel Test 22 Magnum

Published on June 13, 2023
Duration: 8:40

This ballistic gel test compares Winchester Super X 40gr .22WMR and Winchester Dyna Point 45gr .22WMR. The Super X exhibited better expansion and higher retained velocity, while the Dyna Point showed a flatter mushrooming effect and 100% weight retention. The test also noted the impact of ballistic gelatin calibration on penetration depth.

Quick Summary

In a ballistic gel test, the Winchester Super X 40gr .22WMR showed better expansion (0.402 inches) and a larger initial cavity than the Winchester Dyna Point 45gr .22WMR (0.383 inches), which achieved 100% weight retention. The test also highlighted how a slightly thin ballistic gelatin block can affect penetration depth measurements.

Frequently Asked Questions

How did Winchester Super X 40gr .22WMR perform in ballistic gel?

The Winchester Super X 40gr .22WMR demonstrated good expansion, creating a larger initial cavity in the ballistic gel. It achieved a measured expansion diameter of 0.402 inches, though it did shed some weight during penetration.

What were the results for Winchester Dyna Point 45gr .22WMR in the gel test?

The Winchester Dyna Point 45gr .22WMR showed a flatter mushrooming effect and achieved 100% weight retention. Its expansion diameter was measured at 0.383 inches, resulting in a smaller wound cavity compared to the Super X.

How does ballistic gelatin calibration affect penetration tests?

The presenter noted the ballistic gelatin block was slightly thin, estimating this would result in approximately one inch less penetration than if the block were within standard calibration. This factor needs to be considered when interpreting penetration depth results.

What is the difference in performance between high and low velocity .22 Magnum rounds in gel?

Higher velocity rounds, like the Super X, tend to create larger initial cavities and better expansion, but can sometimes dump energy faster leading to less penetration. Lower velocity rounds, like the Dyna Point, may retain more weight but exhibit less dramatic expansion and cavity formation.
