    School me please...

    okay, I've done some reading and such, but I'm hoping for a clear concise answer on difference between 115, 124, & 147 gr bullets and how +P effects each. And this only need apply to 9mm. I know I'm asking a lot, but I appreciate anything that is thrown my way

    Let me also state that I am referring to SD rounds, I currently have 124 +P HST. Not concerned about practice rounds with this question.

    +P (incresed pressure) increases the volicity of the round.

    I tried to find a comparison chart on the web but my google-fu wasn't working.

    Between the three weight 115, 124, 147 is the old argument of heavy and slow or lite and fast. I like you choose the middle ground and go with 124gr

    Try to be a bit more specific with your question.

    In general, +P is ammunition is loaded to a higher pressure than non +P ammunition. All things being equal (bullet weight, bullet construction type, etc.) this usually translates into additional bullet velocity.

    As far as the different weight bullets, in the general case and again, all things being equal, the more massive the bullet, the deeper the penetration.

    alright, I think I'm going to order a couple more boxes of 124 +p just in case it gets harder to find again. Good choice or is it better to just get 124 standard pressure

    I don't really see that much differnce between +P and non +P

    If standard pressure (non +P) is cheaper I'd say go with that.

    I carry carbon DPX which are 115gr, but if I did not not have them I would use Federal HST 124. It is my understanding that the +P does increast the velocity but only slightly and with alot more recoil

    MY 2 cents

    My 9mm is a Browning Hi-Power made in the 1970s, so I don't shoot +P ammunition in it. If I were shooting something newer, I'd probably carry +P if the manufacturer said it was okay.

    As far as bullet weight is concerned, I think an over simplified (but hopefully acurate) way of putting it is that the heavier the bullet, the deeper the penetration.
