Anyone may view these .pdf files by clicking on the yellow titles to access the load data that you wish to view. They will come up in a “preview” mode but you can download the files to your computer and save or print them as you wish. If you need to download the adobe reader the link is in the post above. Thanks to Dan (DBinNY) and Craig (craigf) for their tireless efforts at making this possible! Also, the third post in this thread gives specific information about many of the .45 caliber loads (especially sabotless and duplex) that Richard contributed. Please read it before examining the .45 database. KerryB

The following information has been offered by Richard. He contributed the majority of the .45 sabotless and duplex loads. Please read this information before looking through the .45 load database. Thanks, KerryB
I would like to at least give some parameters for the loads since the way the files are set up, it does not allow for more information.
First of all, the loads were fired from a 23" (breech to muzzle) Pac-Nor barrel on a standard Savage ML II. The barrel had been 26" when new, but dumb-ass me, on the first day at the range, double charged it and put a slight bulge in the area of where the bullet would seat. After some measuring, I figured that by removing 3" from the breech end, the remaining bulge would be back in the area of the powder charge and not cause any looseness of a sabot less bullet. So, it was sent back to PN and shortened. It now has 941 rounds thru it.
I use a recessed factory BP with home made vent liners and never let the hole get bigger than .036" before replacing. The recess holds 11 gr. of N-110. The gun weights right around 13 lbs. with the scope. For glass I am using a Leupold 6 x 20 x 40 with the varmint hunter reticle. A steel Farrel one piece base and Burris tactical rings. Trigger is Rifle Basix set at 2 lbs. Due to shoulder surgery, I have gone to using the Lead Sled which I set on a base that guides the feet on recoil (actually, I put grease on the aluminum pads the rubber feet slide on). The 24 lbs of lead I put on the sled absorb recoil yet still allow the unit to slide rearward without "jumping" up. I believe this method allows for less in the way of vertical shot dispersion.
All the loads and data I provided were shot at 100 yards and were chronographed 10 ft. from the muzzle on a Pact chronograph. The velocity was an average of 5 shots and almost every loads was a five shot group which measured well under 2" and most under 1.5". All shots utilized the "cool-rod" so barrel temperatures did not effect sabots. I also run one patch with four drops of Rem. bore cleaner down the barrel after each shot followed by a dry patch. Since shooting the .45 I can only recall blowing maybe...........one or two sabots. I have found my saboted loads to be generally more accurate than sabot less but not by a whole lot. I used only the Harvester plain "EZE Load" blue sabots. Primers were all Winchester 209's. These loads were shot from June 2009 to Jan. 2010. Because of the cool rod, I believe temperatures have little effect on results either velocity or accuracy wise. In the winter we shoot from inside a heated building.
My sabot less loads are bullets sized to .448" and then knurled up to .451 to .452" with a course file. I am using .060" veggie wads. The 200 gr. Hornady FTX .452 bullet has been the most accurate bullet out to 300 yards.
The most accurate saboted bullet has been the .40 Hornady 200 gr. SST with with Barnes 195 close on its heels.
I must admit I have been surprised at not blowing sabots with velocities in the 2900 fps range. It is my personal opinion that keeping the barrel cool plus smooth (i.e. cleaning regiment) is the key factor.
I hope these loads shoot as well for you as they did for me!
Richard
