My shooting partner and I were talking about the differences in bullet weight. We agree that the 9mm round recoil becomes softer as the projectile weight increases, given it's the same ammo mfg.. The match grade ammo, I sometimes shoot, is 147 gr.; and, it seems softer than regular 147 gr.
Then the conversation switched to .45ACP ammo. Then we agreed the 200 gr. was softer shooting than the 230 gr..
Crazy?
We were using Freedom ammo in fifteen plus 9mm pistols ranging from a Springfield 1911 Range Officer, several STI 1911's, several SIG's (including a p210 6, a X-5 L1 and a X-6 L1), CZ's and a STI Match Master (2011 race gun). This observation has taken place over a couple of years of shooting.
We also used Freedom ammo in the .45ACP pistols. Which were several HK's, including a Mark 23, a CZ 97, two SIG's, a STI Edge and a MP Shield.
Our observations seem to contradict some of the posts made here. And, the differences between 9mm and .45ACP projectile weight and reduced recoil seem inconsistent.
By the way, WWB 115 gr. feels snappy to me. More so than the Freedom 115 gr. round.
