What is meant by .40S&W 165gr ammo. Is the 165gr the designation of the bullet weight, or the powder charge?

I just bought a Sig P229 and was just wondering whats the difference between 180gr and 165gr ammo. I see a lot of different gr numbers, and dont have a clue what they mean.What is meant by .40S%26amp;W 165gr ammo. Is the 165gr the designation of the bullet weight, or the powder charge?
The 165gr refers to the weight of the bullet itself. You will not find a powder charge weight listed on any modern manufactured ammo.


You will however find some ammo that has a +p or a +P+ rating, this refers to the power, usually related to the powder charge.





Just a slightly useful bit of info here, there are 7000 grains in one pound.What is meant by .40S%26amp;W 165gr ammo. Is the 165gr the designation of the bullet weight, or the powder charge?
Well boker is right.The grain is the bullet weight.NOT the powder.I believe the older cartriges like the 38-40 or 45-70 the last # was the powder designation.Now the 185 grain is going to deliver more energy than the 165 grain,meaning hit harder.And more recoil.The 185 gr in a 40cal is a great load.


BTW the 40cal SW has over taken the 357mag for 1 shot kills,by police records.By like .2% Both are at 97+-%.Because of the handling of the guns chambered for 40,and the amount of recoil and accuracy of the round.
the 180 grain bullet is a little heavier bullet than the 165. if your wanting to have the gun for protection id go with the 180 grain. it really doesnt make much difference until you start shooting farther away.
plain and simple how much powder id in the bullet.
165 refers to the weight of the bullet..
