I'll be ordering some Federal American Eagle 9mm FMJ from Ammoman in the next month or so. I noticed that both of these are $79 for 500 rounds, but the 115 grain are $139 per case while the 124 grain are $155.
What are the differences between 115 and 124 grain FMJ? Is one more inherently reliable (or unreliable)? Is the NATO 9mm 115 or 124? What about recoil? I'm presuming an equal load will give more recoil for the heavier round, but I don't know if they're loaded the same.
This will be plinking ammo in 2 Beretta 92's, a SIG P226 and S&W 3913. They'll also be used for a shooting class my family and friends are attending. Should I just save the $15 and get the 115 grain, or is there a good reason I should get the 124? $15 isn't that big of a deal, but it'll let me get that much more .45ACP for my 1911!
