Our tests at a high-tech ballistic research laboratory may change the way you buy loads and guns…and even how you hunt.

1. Is a 3 1/2-Inch 12-Gauge More Effective Than a 3-Inch 12-Gauge?

I’ve always believed the brutal recoil of a 31⁄2-inch 12-gauge magnum negates any ballistic advantage over the standard 3-inch magnum. I have always suspected, too, that cramming what amounts to a 10-gauge load into a 12-gauge barrel produced poor, ragged patterns and longer shot strings that made the extra pain even less worthwhile.

Test Loads:
– 12-gauge, 3-inch, 11⁄4-ounce loads of Black Cloud steel BB shot at 1450 fps (Modified choke)
– 12-gauge, 31⁄2-inch, 11⁄2-ounce loads of Black Cloud steel BB shot at 1500 fps (Modified choke)
Results: Both loads patterned almost identically on a 30-inch circle at 40 yards: The 31⁄2-inch load put 72.6 percent of its shot in the circle, with 77 pellet hits. The 3-inch placed 71.8 percent of its shot in the circle, with 63 hits.

There was no significant difference between the lengths of the shot strings, which averaged 42 inches for the 3-inch and 49 inches for the 31⁄2-inch midway between muzzle and target. Both loads exhibited equal penetration in ballistic gelatin at 30 yards—5 inches—despite the …read more
