    I have 100 rnds of .40cal Remington 180gr MC I just purchased for my Glock 23...

    Is there anything online for EDU purposes of understanding the difference in grains? I see 165 and 180 alot, and that's not getting into JHP or MC... It's a bit confusing for the new guy here.

    Grains is a measure of weight

    1 grain = 0.000142857143 pounds
    437.5 grains = 1 ounce
    7000 grains = 1 pound

    When you see it listed on the side of a box of ammunition it refers to the weight of the bullet; powder charges are also measured in grains but you'll rarely see this listed anywhere.

    Ok, so ballistically, what's the difference between shooting a 165 gr bullet vrs a 180gr bullet?

    Bullet weight, bullet type, amount of powder and type of powder all make a differance in a round's overall performance. Of course the size of the cartridge makes a differance, too, but that much should be obvious.

    Probably shoots "better" because it recoils less. For the most part, given the same caliber, the heavier bullets move slower while the lighter weights are faster, and give more snap in recoil.

    I think its the other way around. The heavier the bullet, the bigger the recoil is. But correct me if I am wrong.

    It depends. At the same speeds the heavier bullet will cause more recoil than the lighter one but if the lighter bullet is going faster it will have more recoil.
