How much smaller are the .36 caliber revolvers than the .45s? Pics? Anybody have ballistics on .36 loads?

Thanks for any info :)

.36 Navy load variations

Just starting on this. Direct, same day, same conditions observation of wonder wad /no wonder wad loads. I used Gun Grease, a commercial over-ball lubricant for the bare loads and no lubricant for the wonder wads. Before starting on this, I clocked some .380 balls over 25 Grains of Swiss.
Velocity 1101 fps Spread 6 rounds- 71 fps.The point of impact was low and several inches to the right of my usual 22/grain/vol equivalent pyrodex load. I was getting hammer blow-back and back-rotation of the cylinder sufficient to screw up repeat function:


22 grains Swiss 3f Velocity Spread
Without wad 1048 35 No hammer blow back
With Wad 973 60 significant" "

22 grains Goex 3f
Without Wad 849 74 No hammer blow back
With wad 801 74 " " "

22 gr/vol Pyrodex P
Without Wad 1015 44 No hammer blow back
With wad 1042 66 Significant " "

Also checked out bullets cast from one of the Dixie Iron Scizzor moulds. The bullet is advertised at 140 grains which would make it like the ones' used for the paper envelop cartridges. In fact, it is almost the same as the brass decorator mould bullets. Slightly lighter at 100 grains but more precise in measurements.
I noted that the pyrodex load was hitting near my sight setting and grouping fairly well one-handed at 30 yards. I laid in a 3" group from the bench at 25 yardsThe group might have been smaller with a more steady rest and better support.



22 Grains Goex 3f 100 grain bullet:
Velocity 831 Spread 36 fps

22/gr/vol Pyrodex P
Velocity 995 Spread 46 fps.

Remington New Model Navy .36 Uberti

...The small bore and increased weight gives the Navy a heafty feel while the .5" shorter barrel makes it appear more compact than the 8" Army caliber. The cylinder walls are thicker than on the Colt .36s but the really interesting aspect of the revolver is that it has significantly deeper chambers than the Colts. We found that our Uberti would hold 28 Grains of fffg with just enough room to seat the .380 ball, and decided we would concentrate on full loads for our initial shooting. Sure enough, the top performers with the 80-81 grain ball and the 125 Grain Buffalo bullet provided calculated energy equivalent to the reported performance of the standard pressure 158 grain lead .38 Special load. - 870fps/ 158 Grain Bullet/ 266 ft/lbs energy. Interestingly enough, current versions of the Special load frequently register velocities 70 and more feet per second lower than the advertised.

380 Ball Velocity Extreme Spread Energy
28 Grain Swiss FFFG 1238 fps 59fps 272 ft pounds

28 Gr/vol Pyrodex P 1181 fps 74 247

28 Gr/vol Hogd.777 1188 fps 49 251

Buffalo Bore .375"
125 Grain Bullet
22 Grains Swiss FFFG 978 fps 62 265

Powder capacity was increased three to five grains over that of a Navy Colt and the top loads provided from 100- 150 fps extra velocity. Consistency with Hodgdons 777 was much better than with most of our revolvers. We were careful to settle the powder and seat the ball with minimal or no compression (as recommended by the manufacturer.)

We clocked the rounds shooting off-hand at 25 yards over the chronograph....

I think the direct answer is the difference in revolver size/weight.

Depends upon the maker and the vintage.

The Walker and Dragoon 44's are very large, and heavy, about 4-1/2 pounds.

Similarly shaped Colt Navy 36 is about 2-1/2 pounds, 7-1/2 inch barrel.

Colt Army 44 has an 8 inch barrel, but is built on a Navy frame, with a stepped (rebated) cylinder. It weighs about the same as a Navy.

The Remington 44 NMA is roughly the size of the Colt 1860, but has the topstrap over the cylinder.

The modern Italian made Remington Navy 36 is actually made on the Army frame.

The Original Remington Navy had a smaller frame size.

Can anyone post 777 fffg .36 cal fps/ball weight data?

There may be some some 777 results for the .36's, but the velocities will vary depending on how much the powder is compressed.
The better 777 results may be similiar to loading with Swiss powder if properly compressed when loaded.

Hodgdon's web site contains two 36 cal load data points, both in an 1851 Colt Navy, .375 Hornady round ball with Wonder Wad:
15 gr by volume fffg 777 662 fps
20 gr by volume fffg 777 832 fps

Ed Sanow published a list of cap & ball .31, .36 & .44 round ball versus modern calibre one shot stops in the Feb 1998 copy of Handguns. I have pasted it but it's a bit messed up.
