I bought these Barnes solids a while back as I found them interesting... At the time they were the only game in town for composition solids. The .44 caliber came in 240 and 280grs. I only found the 240`s even though I listed a want ad in the gun newspaper for a couple of months trying to find the 280`s. They were eventually discontinued for fear of their ability to penetrate bullet proof vest`s (that sounds kind of silly- a bullet that can penetrate a "bullet proof" vest)..Anyway.... I see them as a sort of precursor to todays mono metal solids.
