    I did a series of side by side tests today to see what I could shoot better, 115 gr. Winchester White Box or 147 gr JHP WWB. I was kind of suprised but not entirely by the results. Loading up a mag full of the 147 I settled into the recoil and rythm better than usual. Then a magazine of 115gr and I was a little shocked how much more muzzle flip and noise I was getting. Thats when I realized that there was the possibility that the 147gr was shooting subsonic because of the extra weight.

    Then I loaded every other round alternating 115gr and 147gr. I set up a mock plate stand. I found, that for me, that the followup after a 147gr round was alot faster than the 115gr...

    it could have all been in my head. But I thought I'd report on it anyways to see if anyone wanted to comment on what they've done.

    Still cheap ammo... and I'll have to do a few more boxes for compairison before I switch but I really liked the 147gr today. Good shoot'n.

    I have used both (115 and 147) at GSSF matches. I use the 147 for the plates. That is my slowest event and I always do it faster and better if I use the 147.
    The 147 are a real joy out my G17L!!

    its not like 115s are anything to be afraid of (in terms of recoil), but my experience has been the same...the recoil from 147s is noticably less than that of 115s.

    now, go out and get a box of federal 147s (flat point) and compare them the the winchester 147s. i think you'll find the federals even lighter than the winchesters. the federals chrono'ed about 100 fps less than the winchesters.

    I have had very little experience with the 147's and the experience I did have indicated the heavier bullet had a little more recoil due to more mass out the barrel. I will have to try some of the milder stuff and see if it might improve my times a bit.

    I guess I could crank up the reloading press again but WWB 9mm 115's are so convenient and so CHEAP! :)

    Where and how cheap are you finding 147gr 9mm? All the 147gr stuff I've seen is signifigantly more $ than 115gr.

    i was paying more than $7.50/50 (before shipping!) for federal 147s...thats when i decided it was time to start reloading.

    About a year my wife was buying me some ammo at WallyWorld per my orders but she messed up and bought 147gr Winchester JHP's.

    I figured I'd give them a try just to see how they shot. The recoil was a little bit milder but the accuracy of those bullets was horrible out of my G17. My groups opened up considerably with it.
