24 Νοε 2021 · What is dram and how is it relevant to shotgun shooters today? We'll explain and include a 12 gauge dram equivalent chart. Back in the old days, shooters didn't load shotshells with clean-burning, smokeless propellant.
The term “dram equivalent” is a holdover from the days when shotshells were loaded with blackpowder. Blackpowder is (or at least was) measured in “drams.” This is a weight measure, where 16 drams equal one ounce.
7 Φεβ 2017 · Here’s how you figure dram equivalency: In 12 gauge, a standard 3 dram load with 1-1/8 oz of shot travels 1200 fps. Each 1/4 dram equivalent that you add increases velocity 55 fps. Each 1/8 oz of shot that you add subtracts 35 fps.
28 Ιουλ 2023 · Drams in shotgun ammo are a crucial aspect of determining the performance and effectiveness of the load. Understanding different dram weights and their uses empowers shooters to select the most appropriate ammunition for specific shooting applications.
8 Ιουλ 2015 · DRAM EQUIVALENT. The accepted method of correlating relative velocities of shotshells loaded with smokeless propellant to shotshells loaded with black powder. The reference black powder load chosen was a 3 dram charge of black powder, with 1 1/8 oz. of shot and a velocity of 1200 fps.
16 Οκτ 2008 · "Dram equivalent" is an archaic measure of how much black powder might be needed to duplicate the performance of this new-fangled smokeless powder stuff. The use of dram equivalent as a measure of the "power" of a shotshell should have stopped 100 years ago, but it persists.
9 Φεβ 2008 · In the popular 12-gauge, there are two 1-1/4-ounce loads: one is a 3-1/4 drams equivalent package; the other, a 3-3/4 drams equivalent load. The 3-1/4 drams rounds, often known as the "live pigeon" load, have a normal velocity of 1,220 f.p.s., while the 3-3/4 drams equivalent one runs about 1,330 f.p.s..
