Wow, some kind of initial load. I am surprised at these initial loads.

Warning: This load was intended for Lead Semi-Wadcutter bullets. I used Berry’s Copper Plated bullets and fired from a Ruger Blackhawk. These may be too hot for standard 45 Colt revolvers.

250gr Berry’s CPRN
9.5gr Unique Powder
Winchester WLP Standard or Magnum primers

Fired from a 5.5” stainless Ruger SA Bisley

1st Round 997 fps
2nd Round 1001 fps
3rd Round 1002 fps

120314

These are not listed as Ruger Only. They were in the standard load section under lead bullets.

The 1970 Speer and Lyman Reloading Manuals listed 10.0 grains of Unique with 250 grain lead bullets at 1,000 FPS. Of course this was before piezoelectronic pressure transducers had any wide applications in the ammunition research/load/reloading activities. These loads were annotated as being safe in Colt SAA and "clone type" revolvers.

I personally tried only one 50 round reloading of Keith semi-wad cutter cast bullets (263 grain as cast) with 9.0 grains of Unique in my Colt. I didn't notice any "improvement" in any category of "perceived performance" and resorted to using 8.0 grains for economics and to save wear on my gun. 8.0 grains of Unique has been my standard reload since 1972, though I have tried and use 700X, Titegroup and Winchester 231. The container label on my Titegroup lists 6.2 grains with a lead round-nose, flat-point 250 grain cast bullet at 881 FPS velocity. It burns very clean, similar to 700X.

Unique is my "go to" powder for smokeless loads in .45 Colt. I typically run 8gr of Unique for my target loads pushing 250 gr cast bullets, and 10 gr. Unique for my 250 gr JHP bullets. Both are suitable for most Colt SAA and Colt Clone revolvers.

I also run some really hot near max loads with H110 pushing 300gr Hard Cast gas checked bullets at the lower end of .454 Casull territory. These were developed for bear defense and hog hunting and are only suitable for older style Ruger Blackhawks, and Vaquero's

I load 45 colt and 44 mag with 8 grains of unique for play rounds. With both 200 grain and 240 and 250 grain boolets.

That's 410 ft-lbs which we are more familiar with here in NGF. One joule is equal to 0.74 ft-lbs.

Sorry...I though that it said 555 joules which is 410 ft-lbs. I misread it but I misread a lot these days. I'm even an older gaseous emanation than Popeye.

It’s a 45 Colt day!!! All bs aside, sometimes I have to force myself to load ammo on my desk. Not on 45 Colt day…

I need to make adjustments to the load I used above. I now have an Uberti .45 Colt and those are pushing the max limits. So, I’ll be debating that next load here over the next hour or so while I finish priming brass.

126972


I checked my numbers from my last inventory, I’m 120 brass short… grrr. Grabbed 400 new brass while in Scheels last night so I have 633 to load.

Also, found a new loading buddy in my loading room…

You always need a loading buddy. Mine are my little chihuahuas.

Did some experimenting with TiteGroup today. Not my powder of choice for 45 Colt but I do have 8lbs of it still so I’m going to put it to use.

Also had some 200gr lino type semi wad cutters for 45acp. I’m never going to use them in ACP. So I decided to use the for testing. Because they are ACP bullets, I used my ACP factory crimp die with a decent crimp.

First test was 6.5gr at 1.650” this is 0.050” over length. Test gun was 5.5” Ruger Blackhawk Bisley. Winchester primers.

126988


57fps spread. Not terrible but weak.

Next I tested 7.0gr at the same length, same gun. Different primers. This time I used CCI primers (it’s just what I grabbed).

Excluding the outlier, the 1/2gr extra only made 30fps extra velocity (probably the primer change). Only 2 of the 4 registered properly.

126989


126991
Next, I tried them in the Henry. Unfortunately, they were too long for the action, but I did test the velocity anyway.

126990


Not a fan of the 97 FPS spread but if found this common with shooting TiteGroup through a 20” barrel. Excluding the outlier, the energy was sufficient from a 45 Colt.

126992


Had to get them to cycle in the Henry so I shortened them as much as I felt comfortable doing. 1.631” and put a good taper crimp on them.

126993


That’s all it took to get them to cycle in the Henry. Fired 4 test rounds. No hang ups.

So this one is a new one on me…

Only the new Winchester brass. 95%of the time, I buy Starline. Just prime and run them. Nope, gotta resize these bastards.

I’d have been done with these by now but I was in dire need of shelving for powder and primers. Took some time and went to Springfield and bought some. Now I can actually see everything I have. Just kind of wraps around the ceiling.

I run every new case through a sizing die. Most of the time they are fine but sometimes you can tell some are different by the resistance going into the die plus if there are any case mouth digs from the packing and shipping process it will remove them.

I reduced the 9.5gr of Unique that I used in the Berry’s loads to 9.0gr. Loaded some of these hard cast 250gr and was surprised at the results.

Fired from a 5.5” Ruger Blackhawk Bisley.

Round 1: 1043
Round 2: 1011
Round 3: 1050
Average: 1035 = 595ft lbs.

I don’t know what the pressure is but I don’t feel comfortable using that load in the Uberti. Those are moving about 200 fps faster than expected. Going to try 8.5gr and see where we are. Minimum load in my book is 8.4gr.

8.5gr produced the following from the 5.5” Ruger Bisley.

Round 1: 969
Round 2: 962
Round 3: 991
Average: 974 fps, 527ft lbs.

Still too hot.

8.0gr of Unique. Same gun. Same bullet.

Round 1: 941
Round 2: 937
Round 3: 887 < outlier
Round 4: 935
Round 5: 944
Round 6: 923

Average: 936 fps, 486ft lbs. Excluding the outlier.

At 8.0gr, they are producing -4 FPS from what the book is saying 9.5gr should produce.

I am going to table any further testing and give y’all a chance to chime in. Lead bullets are not my area. I’m guessing the hard cast are creating near FMJ resistance in the barrel. 7.8gr is the max load for an XTP 250gr in my book.
