That truth about guns review was pretty good. It covers both
tungsten matrix birdshot and
lead bb's. I feel more confident now about my choice of Remington's Hign Density BB load, given that it uses a tungsten matrix bb instead of a lead bb.
If you look at that study, it opines that #2 Birdshot would likely be effective an ultra close ranges (inside the home), but be ready with heavier follow up loads. For #1 it is less conclusory but the raw data for tungsten matrix suggests it may be more effective than #2 but does not quite measure up for use as a
tactical shotgun load.
{Then it finds that
lead BB loads suffice for close tactical loads, meet minimum requirements for medium range tactical loads, but fall short for general tactical use.} That is what I originally posted but it is NOT what was found and it is NOT what Robert Fqarago wrote in that article, which was that:
lead BB has it’s place, being a reasonable balance of penetration and pellet count. That being said, it is not recommended for medium range work. #4 buckshot is the minimum pellet size we recommend for general tactical applications.
(Emphasis added by underlining.)
Those were lead BB, not tungsten matrix, and your concern and mine is home defense use. Is tunsten matrix BB good for medium range work? I do not know but assume it is reasonable for short home defense distances in which over penetration is a concern.
Thanks to jmortimer for sharing this.
