“…We sampled each ammunition type ( n = 10) to determine shot charge (payload) weight, number of pellets, and muzzle velocity, and conducted comparative pattern testing under no‐wind conditions at a mean temperature of 15.6° C and 1,250‐m elevation. Because shotshell patterns are influenced by firearm type, barrel length, choke, and distance (Compton , Compton et al , Warlow , Jones ), we standardized testing procedures by using one shotgun, choke set, and distances to isolate differences due solely to ammunition type. Patterns for each load were fired at 18.3 m, 27.4 m, 36.6 m, and 45.7 m from a Remington Model 332 with 76‐cm barrel (0.185‐cm diam bore) using improved cylinder (0.183‐cm), modified (0.180‐cm), and full (0.175‐cm) Remington RemChoke™ screw‐in choke tubes (Remington Arms Company, Madson, NC).…”

With approximately 100 million shots fired at mourning doves (Zenaida macroura) annually, it is incumbent on managers to determine whether changes in ammunition will substantially alter harvest metrics or hunter satisfaction. We compared mourning dove harvest metrics for 1 lead (Pb 7 1 /2, 32 g) and 2 steel (Fe 7 and Fe 6, 28 g) 12-gauge ammunition types using a double-blind field test in central Texas, USA. There were no differences in the number of attempts, or number of shots fired among ammunition types. Hunters were unable to distinguish the ammunition type being used in the field, and we detected no relationship between ammunition type and level of hunter satisfaction. Field analyses detected no difference in doves bagged per shot, wounded per shot, bagged per hit, or wounded per hit among the 3 ammunition types. Necropsy analyses detected no difference in the proportion of birds with through-body strikes, mean penetration depth of through-body strikes, or mean embedded pellet depth among ammunition types. Ammunition and choke combinations that produced higher pattern densities yielded more hits per shot and produced more total strikes per bird, resulting in a higher percentage of birds with embedded pellets, more embedded pellets per bird, and a higher proportion of birds with broken legs. All 3 ammunition types retained sufficient lethality to harvest mourning doves under typical hunting conditions. Our results demonstrate that when the ammunition type used provides sufficient lethality for pellets to penetrate vital organs, pattern density becomes the primary factor influencing ammunition performance.
