115 vs 124 grain 9mm ammo

[zincwarrior]

My M&P Pro shoots 124 grain with just slightly tighter groups. However, unless its for competition, or defense, general plinking-115 has always been fine. I too don't notice an appreciable difference recoil wise on commercial rounds.

I find 115g to shoot a bit higher than 124g out of both my CZ p09 and friends p07.

I have never noticed a difference in target loads. I have always used 124 for SD though.

Except for shooting closer to point of aim on a fixed-sight pistol, I can think of none. Perhaps the 124(ish) grain projectiles will more likely through-and-through penetrate a torso, but that's also dependent on a host of other factors.

IMO 115 gr. is usually the cheapest loose bulk packed like WWB. Fine for range and is most sensitive to limp-wristing, makes for good practice. 124 gr. like Geco/RWS, Win. NATO when reliability is needed.

124/125 seem more accurate for me in fullsize or in LC9.

For each there is a standard load and a +P load.

Allegedly older European pistols were designed for 124g and swallow it better.

Frankly my Walther P1 and BHP and quite happy firing 115g all day long.

I load everything from 90g to 147g load ranging from target to +P and +P+. My CZ 75B enjoys everything I feed it. I try to load velocity's that mimic that of the SD ammo I use. HST and Gold Dot 124g +P's.

I've had better accuracy with 124 gr when comparing say Fiocchi 124 vs. 115.

Same with Federal American Eagle 124 vs. 115 grain ammo
