    165 vs 180 grain .40c ammo question

    looking at different available ammo at the store and noticed 2 brands of ammo with the only difference being 165grain for winchester and 180 for PMC (i think was the brand). Federal
    i am a little confused with what i have found - is the 'grain' measurement the weight of the full cartridge/bullet etc?

    In handgun ammo, the grain refers to the bullet weight. In your situation, the 165 Winchester ammo weights less than the 180 PMC. The lighter the bullet, the faster it travels. However, the lighter bullet have less power behind at impact than the heavier. I believe I have read elsewhere there are approximately 7000 grains in a pound.

    In simple, the weight of the bullet.

    What are you going to use the ammo for? range? self defense? Is it FMJ or hollow points?

    Re: 165 vs 180 grain .40c ammo question

    No worries, everyone has to learn sometime. For the range, and for no other reason than uniformity, I would use what ever grain FMJ for the range that you're hollow points are that you use for home/self defense. They'll shoot more similarly, though they won't be identical. I dought very seriously that you'll even be able to tell, even at ranges in excess of 30 meters. It's a lot less critical with a pisol vs. say a rifle at long distances. But, if they are the same price, uniformity in any area you can achieve it is best for training. I personally use the 180 grain FMJ's for practice, and I carry PDX1's in 180 grain for self defense.

    Oh, FYI, +P if you don't already know stands for "over-pressure" ammo. I don't think .40 comes in +P, as I think it's already made to spec???? Someone else will have to chime in on that, i'm not sure.

    Re: 165 vs 180 grain .40c ammo question

    thanks for the info - this is a new handgun and i ran a couple hundred rounds through it. i grabbed some of both types figuring this is a good time to vary things a bit - not that the gun needs breaking in - but i know the owner does

    i know i pretty much thought all (or most) ammo is the same and am finding out this is surely not the case

    When you shoot one then the other which has more recoil or muzzle flip or is there no difference?
    Things are more the way they are today than they've ever been before.
