Accurate loads for 125 9mm boolits?

[pergoman]

I have several different molds that throw 120-125 gn. boolits including the Miha hp, Lee tc, and Lee rntl. I also have several thousand #377(125 tc) cast tips I couldn't resist from Wideners. I have yet to find a load combination that pleases me as far as accuracy goes. I am still trying because I just know it is out there. I have just about every powder known to man, a Ransom rest, a range 1/2 mile from my back door, and more than half a dozen different 9mm pistols. I have Jword loads that work great and 105-119 grain cast tips that work great.
I am not concerned about making a power factor so velocity doesn't matter as long as I can get them to function well. I am a competitive bullseye shooter who knows what I can do as well as what each gun is capable of. These loads are meant for less demanding shooting games such as steel, PPC, etc. 10 shot 25 yard groups as big as a fist just don't cut it for my needs, especially when the guns will print 10 into 2" with other loadings.
Any recipes are appreciated

Here's some loads that work nice for me. They are the Mihec 359-125 HP shot from a Ruger SR9c. WSP primers, COL is 1.096. I shoot at an indoor range, so no 25 yd groups and you are likely a better shot than I. The sizes below are 5 shot groups shot offhand at 8 yds.

4.8 gr AA #5, 0.59 inch
4.0 gr HP-38, 0.78 inch
6.3 gr HS6, 0.50 inch
6.6 gr HS6, 0.74 inch
3.3 gr Clays, 1.08 inch

I am in the process of working up loads for this boolit using CCI #550 primers (I am kinda short on SP primers and am saving those for 380 Auto). Hope this info is useful.

The guns will print 10 into 2 in. Whats the problem??? How did IMR 7625 do for you?

5.5 grains Alliant Power Pistol; 4.8 grains Ramshot True Blue. PP is a little faster, TB is a little cleaner, both are good loads for my guns. You need to work up your own if you use either.

3.5 grains of Bullseye

In my experience, too many powders leads to too much experimentation.
My current plan is one powder at a time and one average load with three +/- .1 grain variations on either side of the average I find in manuals. If one of those seven loads isn't a winner - then it's time for another load or another powder.

I have settled on 5.5gn HS-6 under the Mihec 125 hp with an OAL of 1.060". These will put 5 into less than 1.5" at 25 yards off sandbags or when run through a gun in my ransom rest. These produce velocity of roughly 1100fps, depending on the gun. 5.0 gn also worked well at around 1000fps.

3.6gr BE under that boolit wght works well in 3 of my 9mm's. I have other data at home but remember this as I used it Saturday. This was with Fiocchi primers

From my experince with my 9MM & 38 super pistols 5 in all . I size cast bullets @.357 dia even if the bore is .355 dia.
Dont use mixed brands of brass in a given load at least sort cases by mfg in a given lot , if really serious first size cases then ck oal and sort that 9mm brass @ to between .750 to .755 length in one lot for best accuracy.
I have also found that med fast to med burn rate powders have given me the best accuracy in every pistol over the faster powders with cast and jacketed bullets.

4.5 grains Unique cycles and is accurate. My mold drops the 125 gr. RN at 120 gr.
