I decided to try some 9x23 loads (124 target loads) in my Witness chambered in 38 Super These are said to run 1450fps. I chronographed them and I was getting 1479 to 1544fps with the majority of the box over 1520. this is out of a 4.5" barrel.
I was doubting the operation of my chronograph, but I checked my 230 grain 45 ACP loads and they were running the same as usual a conservative 750-800fps. There is slight primer flattening with some pin set back but nothing serious.
Did I just get a real good box of USA ammo or is something awry? the pistol was very controllable, no different that running 38 Supers. Function was flawless, All 18 rounds!
I would also like to reload some heavier than normal bullets weights. Rainier makes a 151grainer for the 38 Super. Anyone have experience with these heavier projectiles? peticularly with AA#7 or AA#9. I like the 38 Super, I think I'm going to love the 9x23!
Wonder what the Win. 124 grainers would do over my chrono out of a nice
5 or 6" 1911 pattern?

Thanks

My 5" Gov't model does about the same with the Silvertips, and is only slightly slower with the 124 grainers.

When it comes to heavy bullets, the Hornady XTP 147 is the first one I have found that seats without bulging the brass. That Winchester brass is thick!

Very consistant with my own experience. A friend's 5" Gov't spits them out at 1500 fps consistantly and in the cold.

Win brass is thick. You might try getting some Starline but they are pretty beefy, too.

tfunster...you said USA ammo? Could it be Winchester White box or Silvertips? The White box soft points run (best of my memory) under 1400 fps in my 9x23's and the Silvertips run about 1550 as someone else stated.

I have played with 9x23 for a good while and chronographed many, many loads. This is a superb pistol round phenomally accurate and flat shooting. I don't load them real hot, somewhere just above .38 Super, and the brass will be lost before you wear it out.

Can someone clear up the 38 supercomp vs 9X23 question? Brian Enos says that the Dillon Dies for 38 super will work for 38 supercomp, but that the 9mm dies are used for 9X23. When you look up 9X23 in catalogues and Starline stuff, the 9X23 is equated to the 38 supercomp. So, is the Starline product tapered like the Winchester 9X23, or is it simply a beefed up 38 super?

Starline used to name there 9x23 brass 9mm Super Comp
The newer brass is head stamped 9x23 Comp to help avoid confusion.

Read ClarkEMyers post on the 9x23 he has it pretty much dialed.

The 9x23 and the 9mm Luger are the same dimensionally except for case length and case web thickness.
Use 9mm dies for 9x23 cases

(Note: depending on reamer used 9x23 OAL can be increased up to 1.280 or more)

9x23 has a taper, like the 9mm para.
38 super has no taper, so I tend to think the 38 SC will not have a taper either.
Basically, the 38 SC is a 38 super w/o the rim. IIRC
