My indoor range has a limitation of 20 yards. I'll give you my example of accuracy. At 15 feet with iron sights I split a popsicle stick in half free hand. I also noticed the decrease in muzzle flip and being in an enclosed area the additional noise created was negligent. I load my own 9mm. My best accurate loads are extreme 124gr copper plated with 4.4gr titegroup and 1.125 oal.
