I have been shooting the Remington Sub Sonic Hollow Points out of an old Marlin Model 25 Bolt Action Rifle. While I have not shot any .22 Shorts for many, many years, I can not compare the Sub Sonics to them. However the Sub Sonic Remington Hollow Points produce about half the muzzle blast that regular Hi Velocity Hollow Points produce. In addition I use the Remington Sub Sonic Hollow Points for close quarters pest control, and to my surprise the bullet hitting an animal produces more sound that the gun going off (muzzle blast). They are about as accurate as the better shooting .22 LR Hollow Points I have tried in this rifle.
