Its a Uberti Marked BZ for 2005 Production. Well timed and with the measurement I expect with the Uberti .44s- .450 chamber and Barrel as close as I can read a caliper. Action is well timed and the trigger is pretty good with a slight hitch before release. This is not a problem with a gun that is this heavy. Metal work, fit polish blue are all excellent and the case hardening is pretty for a cyanide process.

I got some tool heads with the intention of coneing the seating ram for eventual use with traditional shaped bullets. Then looked at the ram and it is already coned for bullets much like 19th century revolvers and in contrast to most replicas which are dished for loading round ball.
I did start out my shooting session with the 200 Grain Lee Conicals cast from Wheel weights and run through a .452 Sizer. The chambers would allow seating with 45 grains of 3f and equivalent but not with 50.

It was necessary to clean the chambers after each cylinder full of black powder for easy seating. I also shot .457 round balls over 60 grains of Swiss 3fg and Pyrodex P. Data from a kit-built Uberti matches the velocities I got with pyrodex and I suspect this would be the case with other powders too. Energies for the Bullet loads and the round ball were generally in the 500 ft pound range which matches rather closely with the heaviest standard pressure factory loads for the .45 Colt and several other powerful modern pistol cartridges. Sixty grains under the ball is a full load and there is some difficulty in getting the ball compressed beneath the chamber mouths. It would probably be a good idea to consider 55 grains of black powder and the equivalent of Pyrodex P to be the maximum load in order to save wear and tear on the seating mechanism.

As I shot over the chronograph with the 200 grain bullets, I noted that they struck about 10 inches high at 40+ yards and just a bit to the right. Shooting was done from seated position on the ground resting over my knees and the group went slightly over 4".

finding the point of impact to be, as expected, lower than that with the bullet and also centered over the sights.

Twenty five yards seems a bit close for shooting a revolver this big but I did it anyway. The two out the the left were from my first six and by the time I got to the next cylinder, I was catching on even though I was starting to feel the weight of the gun.

I used a rubber band and then tape to keep the lever from flopping down- which it would have done on every shot otherwise.

All-in-all, this is a very worthwhile replica to have. Although it was the State Of The ART revolver for only a few months in 1847-48 and improvements set in immediately after the first 1100 were produced, it did leave a large enough footprint on north american history that people are still talking about it 150 years later.

Picket Bullet.

Little discussed key point about the Walker Colts. The primary projectile for it was a picket bullet-a triangular, sharp pointed flat based thing with almost no driving surface in contact with the chamber and bore. It drew complaints from the field, was probably instrumental in blowing up a large number of the pistols and has no features we now identify as being essential for an accurate pistol or revolver bullet.

Pedersoli, in addition to the decorative brass moulds, makes a blue steel single bullet mould for the Walker. It is a serious attempt at exactly duplicating the orignal bullet and seems to succeed admirably. When I looked at the bullet, my heart sunk. I never expected to be able to successfully load and shoot these things. The loading ram in my Uberti was already counter sunk as if for a conical bullet. I bored it deeper and coned it so that it would fit the needle-sharp profile and engage the ogive of the bullet. This worked better than I had any reason to expect. Prior to loading, I slightly beveled the base of the bullets so that they would sit on top the chambers.

Once I got the bullet into the loading slot and lowered the rammer over the nose, a slight wiggle of the chamber brought it into perfect alignment for seating. Measurements indicated that the correct powder charge would probably be 40 grains of fffg. The bullets seated easily over this charge. After the initial shooting, I upped the charge to 45 grains and added about 100 fps to the velocity. this was a maximum charge and I had to exert a good bit of pressure to fully seat the bullets.

I still didn't expect anything positive in the way of consistent velocity or accuracy and was amazed when my first shot from 30 yards hit exactly on my point of aim.

Upshot: the picket balls worked very well and probably proved accurate to some considerable range. They were slow to load as reported by period sources who pleaded for a return to the round ball and incidently to the Paterson five-shooter. They obey none of the rules we have come to accept about handgun bullet design. I like that. I had thought that the iron mould would be used once and then put back in the collection of neat (more or less) stuff. I now know that I will put it to use and make it a standard for the Walker Rep.

mec - many thx for a great write-up. Makes me want to try one of these but my cap and ball days are somewhat intermittent now.

I too am amazed re the Picket bullet - and am still wondering how that thing developes a true (and non deviant) axial spin with those proportions. I can think back to a Hensley and Gibbs 6 cav' mold I used for 125 grain 9mm's - where the driving band area was very minimal - they keyholed nicely!! I sold the mold!

I guess tho results here speak volumes and the apparent accuracy is remarkable. So - I wonder, could you recover one of those? I wonder because it'd be interesting to see how much takes engraving.

Thx again.
 
I believe this was a carbine bullet and since nobody had designed a revolver bullet before- it got elected. I suppose they must have done some r&d on it and found that it would stabilize. I did find a report made to the 31st congress in december 1849. The officer-engineer who wrote it was begging for a return to the round ball and the five shooters. He didn't like the bullet and he didn't like the overlong Walker and dragoon cylinders necessary to get enough powder behind the bullet.

anyway, take a look at this! Marty robins flame thrower and a half.

didn't catch any bullets this time but may try in the future. It would be interesting to see if they start to tumble on impact. I was just glad they didn't keyhole through the air.
