I know I'm not going to surprise many with this post .
If lighter a longer barell helps
If heaver the recoil impluse is spread over a longer period of time .
Heavier slower projectiiles will stay in the tube longer and be subjected to muzzle flip a bit more than lighter rounds . The lghter faster rounds print low , the heavier slower rounds high .
opinion:
115 is nearly silly light
124(5) is still a bit on the light side but Mas Ayoob went to a lot of trouble to document it's effect .
147 is nearly too heavy but recent (to me anyway) advances in bullet construction make it a fair choice .
How come no one has attempted to popularise a 135 ?
It's just words folks , and I do not cary a 9mm for defense (and never will) .
I do not use 185's or 200's in my .45. I don't like the recoil . I don't like where they print . I don't like the muzzle blast and my weapon somtimes refuses to feed , eject and occasionally locks up in recoil .
Summary:
Every bore and barell length has a sweet spot for velocity and bullet weight .
Again I wonder if someone went to the dtrouble of developing a 135gr would anyone buy it ?
Ok I'm sick of me too
have a good thread
