I've shot Cci snake shot in 40, problem is not hot enough to work the slide so stovepipe. They feed ok. Alum. case. Look like 10 neck sized. May have to try WST load.
Whatever!
Case is a 10mm neck sized to 357 sig dim. Since I don't have a 40 anymore I have to depend on info from my neighbors on how a 40 feeds and such. I didn't realize a simple favor could get so complicated. I'm told my 10's necked down and sized do feed and eject.
I've been told that most 40 S.A. actually H.S. on the extractor. I was looking for something that will work for snakes in S. Tx. when hog hunting. CCI (I think they use #9) only gives me one shot. Pattern is only good to maybe 5 ft. but that should be enough. The stovepipe is the problem, have to clear it vs just re-racking the slide. Sound like you have a good solution.
Whatever!
Looking to try this as we have rattlers in my area. I've got 357 sig dies and have sized 25 10mm cases to chamber in the 40. One question. Do you use any type of wad between powder and shot, or they all "floating" arround together?

I haven't built any in .40 (don't have a 40 or 10mm yet) but have done a lot of other calibers, I would at least use a disk wad, better yet a sleeve (take a rectangle of thin cardboard or plastic, PETE drink bottle might be ideal, cut an 'x' in the middle so you can wrap the wad around a dowel and insert it into the case.) Could try that over a disk wad to see if that improves pattern and or function? If it isn't working the action, a little hotter powder charge may help that, but the hotter the load the more of a hole in the center your pattern will tend to have. Look at loads with a boolit weight similar tobthe weight of your shot load but start low & sneak up on that powder weight.
I'm toying around with making 40's & 10mm shot loads, my problem is I no longer have a 40 or 10, have to rely on a friend to 'test' my loads but he lives a fair distant from us. Am using 10mm magnum brass, for the 40 I have to cut off about an 8th inch then it will be a length that will work, use a .357 mag crimp or sizer die to form a shoulder, works quite well. Can also do a roll over crimp to hold wad over shot or a 'notch' die to star make a star crimp, notch die does take a little bit of shot weight away from what a roll crimp gives. #12 and # 9 shot is all I have at this time to try, so far the 10mm has 'stoved piped' after each
shot which really does not bother me, you just don't need for them to rapid fire.
Make my wads by using large rifle brass cut off just below ejector grove, sharpen case neck mouth, use drill press to cut 'press' out the wad.
Don't know why i'm doing this but for sure i've got the time and i do enjoy.
Cheers, Woof woof Gus an me
Thanks, not sure how I missed that...

every time I get serious about making shot loads in pistol shells I usually revert to using #9 shot because its the smallest I have although others report great success with smaller shot like #11 and 12 and this is one item ive yet to put into inventory for one reason or another.
how far a spread should be expected from 80 gr of 7.5 shot out of a g22 or other semi auto? at 3 yards? 5 yards?
What you said about the case swelling into the rifling in the barrel- I used military.308 because that was what I had.
Well, the recut and reformed .308 Milsurp cases were very thick, especially in the necked down .45 case, but they worked perfectly and all ejected smooth thru two different pistols.
So maybe the thicker case kept it from expanding into the rifling.
But, in your case, it's best to reduce the powder charge, a fraction at a time.I used WW231, I think 6.1 grains.
Also, others have used Unique and even 700x with success.

I have used neck cracked 257 Roberts cases, 243, 308, commercial and military cases, get some rifling on the case necks but not enough to hold the case in the barrel. Good function is my goal
