I have shot ton of it out of one of my 1911. But I was running them at 910fps. I like to have a good margin :wink:



I did shoot a few through some M&Ps and they seemed to work fine but I didn't really do accuracy testing, more to just to see if the loads would run the gun. They do

I was at the range yesterday and shot some 147gr cast at 930fps. I was having some problems with keyholing, as close as 5 yards away.

Slowing them down isn't going to stop Keyholeing. You will need either another bullet or another barrel.



I remember now shooting some out of Yamil's gun at 10 yds no problems, but I know his gun liked WWB beter for group size.

I seem to be getting some keyholing with my 147gr loads too.



Zero 147gr JHP

Titegroup 3.35gr

WSP

1.125" OAL

Speer once fired brass



I haven't investigated further with the load. Just got married and was shooting in the GA State match this past weekend. I'm not liking the fact that I may have to rebarrel the gun to get rid of the issue though. = I have two M&P 9mm pistols set up for USPSA Production and wanted to shoot a 147gr load for the soft recoil benefits. I've shot up all my Zero 115gr JPH loads I worked up over Titegroup 4.7gr. Those thigns were dead on accurate but to damn snappy for me.

yeah matter of fact

i'm shooting 147's, precision Delta's at about 877 give or take a little..



titegroup 3.4 1.150 oal. .379 .380 crimp mixed brass Win SR primers.



Shoot great.. i had them a tad lighter but got 127 at the chrono and bumped it up a little.. had 129.5 at the last match..



I won't say it the most accurate load but it's ok for Production. 13lb spring stainless rod, going to tungsteon though.. i like the front weight..



No keyholing no problems cycling, shoots pretty soft.

Keyholing 147 Zero's are not rare. I think a couple of years ago they changed something and where they used to shoot great in my CZ they started going sideways. At the same time 2 other people noticed the same problem (one of them USPSA Production GM). I switched heads and the problem went away. Ever since then I keep on hearing people having problems with Zero's so I never had a need to go back and with their current prices I would be mad to go back. On the other hand, pleanty of guns shoot them fine. I think their design plays well with some barrels and really badly with others.
