Quick Answer
To test different slugs for personal preference, set up a shooting range with various targets at 25 yards, and test multiple slugs with the same rifle and ammunition, comparing accuracy and penetration.
Choosing the Right Targets
When testing slugs, use a combination of paper targets and ballistic gelatin to assess accuracy and penetration. Place the targets at 25 yards to minimize the influence of wind and atmospheric conditions. For paper targets, use a large, dense sheet to represent a human silhouette. For ballistic gelatin, use a standard 10% ordnance gelatin block to simulate human tissue.
Measuring and Comparing Performance
To accurately compare the performance of different slugs, record the group size and penetration depth at 25 yards. A group size of under 2 inches indicates a well-balanced slug, while a penetration depth of 12-18 inches is desirable for hunting larger game. Use a caliper to measure the group size and a ruler to measure penetration depth in the ballistic gelatin.
Selecting the Best Slug
After testing multiple slugs, select the one that consistently produces small group sizes and deeper penetration in the ballistic gelatin. Consider factors such as weight, length, and rifling to optimize performance. For example, a 3-dram, 2-ounce slug with a 1:12 twist rifling and a 1.75-inch length may be a good choice for hunting larger game at longer ranges.
