![]() The truth is, there’s a time to slow things down and keep it quiet, which is why subsonic ammo exists. Not only is all that velocity-crazed volume hard on the eardrums, it’s also unfriendly to the pocket book, as anyone who has recently bought a box of ammunition for one of the newest long-range super cartridges can tell you. Just stand next to a muzzlebraked magnum or a straight-piped hot rod to get the picture. The drawback, however, is the noise pollution that accompanies our fixation with speed. From muscle cars to overbore rifle cartridges that burn barrels and launch bullets downrange at well beyond 3,000 feet per second (fps), we operate on the assumption that faster is better. At 25 yards, point of impact shift between the two loads was small so switching between the two shouldn't require re-zeroing of sights and optics at this distance.As red-blooded Americans, we’ve long ago come to embrace our ancestral need for speed. It didn't appear to be as accurate as Subsonic Hollow, but I've changed my accuracy testing from 5 rounds to 10 so it's not a perfect comparison. In my rifle, accuracy with this load was minute of quarter. Knowing this, it's understandable to see velocities in the 1100 fps range. My data was generated with a much shorter 18.5 inch barrel and chronograph screens positioned at 25 yards. I learned they establish their velocity in 23 inch test barrels with chronograph screens positioned at the muzzle. My velocity measurements came in quite a bit lower so I asked Eley about it. Eley publishes a velocity specification of 1250 feet per second for this load which falls in the ballpark of what US consumers expect from high velocity rimfire ammunition. High Velocity Hollow runs about 200 fps faster than Subsonic Hollow when tested in the same rifle under similar conditions. You can refer back to my previous test of Subsonic Hollow HERE. As I mentioned at the beginning of the article, I was really curious to see the performance differences between High Velocity Hollow and Subsonic Hollow. ![]()
