I had shot up all the 80 grain variety before I realized that the other package had 130 grain bullets in it. So, I didn't chronograph the 80s but am willing to bet the velocities are about what you get with balls which are the same weight - 1,000- 1,100 fps. The picture group is two handed standing at 25 yards with the 80 grain bulletand is way bigger than the capability of the bullet. I was shooting in gale force winds with the sun right in my eyes and the front sight looking like a pillar of fire. The group with the 130 grain bullet was about 3.5 wide by 5 tall- again blaimed on the conditions. The 80 grain hit exactly on with my ball -set sights The 130s were two to three inches higher. I found that 22 gr /vol of Pyrodex P would work under both weights and I believe that black powder would compress enough for that charge to work with it also. my notion is that both bullets are about as accurate as a round ball or so close that I wouldn't be able to prove the difference.

Interestingly the advertised energy of a .38 special round nose given 870 fps/ 158 grain bullet its 265 foot pounds. This load gets 269 ft/lbs.

If I had seen any problems with this bullet or anything at all that might need to be changed, I would have PMed Manyirons rather than open posting. I have no suggestions for any changes at all or any complaints. The bullets drop into the chambers flush almost flush with the mouth. They are easier to load than round ball or any traditional rebated base conical bullets. The seat with good pressure in the fairly large Uberti chambers and there is no bullet walk. I shot one of them into two one gallon water jugs and the first ruptured very impressively. Second one busted open pretty good too. Bullet went through both jugs a thin piece of rot-wood and either buried in a cedar log or bounced away.

Tried finding some of them in dirt but never did. I wanted to look at the rifling engraving . I know that there is full lenth contact as the small diameter portion of the bullets will not go into the barrel either at the muzzle or forcing cone.

On- target signatures are the same as truncated cone wadcutter bullets

Many Thanks Mike!

Mike!

Excellent as always! One teensy thing, aint mine! Credit for this goes entirely to tha Big Kraut, i'm just helpin!

Will send some more culls i found (Were behind/under a cleaning cloth on bench.)
 
" I plan to use a 61 Uberti with 20gr 777."

Looking forward to that.

Oh I know about the gunsmith. I was just kind of nervous about using the K-Word on open forum.
 
Mike!

No trouble, we use KRAUT as an affectionate term, not insulting, beyond that easier ta pronounce than his name!
 
I figured. Sometime back a newspaper cartoonist was railing against all the pc they have to put up with now. He put up a picture of A. Hitler with a really blanched look on his face captioned something like " Der Fuerer was hurt and offended when Winchell used "The K-Word in his column."
 
Huh?! Well Mike, we don' need no steeekin' PC! He aint worried, i'm not and if hitlery klingon whines, well, ya can GUESS what I'D tell her!

Hi Dwave;

So far just go direct;

.36 80 and 130 solids'll be first up in production, followed by .36 h.p. followed by .45 solid then h.p.
 
Looking forward to that.

well I have both 15 and 20 gr spouts. Are you thinking 20 won't fit?
I haven't used the 777 any yet. Do you think its as problematic as some people say?\
because if it is, I certainly don't want to wreck this one, like the owner of the 60 I bought did.
I'd gladly listen to your advice about it.

come to think of it, those 130s aren't going to fit with 20 gr. (and the wonder wads)
 
The nose profile on these is going to smack harder than any others I've shot -particularly the heavier one.
 
Should be some in about a week, he redesigned slightly ta improve. And yup, actually lives in countryside, postal address is in town, closer ta Bremen.
 
Thank you for the information Manyirons, I think I will drop him an email next week and see if he has any for sale. I am interested in these bullets, and if he is near Lancaster, I can just make a short trip and pick them up instead of mailing them if he doesn't mind.
 
130 grain works in my navies with 20+ grains but all three have deepend chambers, Steve! let me know if your stock will will take 20?
 
450 feet above sea level. No idea if this is important or not.

The 22/ gr/vol pyrodex P allowed the bullet to seat deep enough that I am pretty sure that you can use that amount of black powder and am sure that h777 will fit in fine. H777 behaves erratically if compressed to any extent. For that reason, the lower charge may be better. The tendency is for h777 to do its best with the bullet on top of the powder column and very little additional compression.
 
Why would anyone be touchy about Kraut? I'm German on my dad's side, trace the lineage right back to ol' Carl Giesecke himself landing at Galveston in 1836, the very day they were fighting the battle of San Jacinto. Ballsy, eh? :D Even found a book about the guy, "Germans and Texans" by Walter Struve, himself a descendant of the old boy. I gotta say, I've been called a lot worse names and nothing I can type here without getting censored. :banghead: :D
 
I want to know the glossochronology of Kraut. Does it come from Sourkraut or does sourkrout come from krout.
 
Thanks mec.

Yes actually elevation is important. I spent a lot of my marine corps time in artillery. Air density, pressure, temp, elevation, and rotation of the earth all are key players. Maybe not at 25 yards, but powder burning rate is affected, and darned if I know how to measure it in such a short distance.

So if I get erratic groups still during the third cylinder, I'll back off to the 15 grain flask. I plan to only take the 80 gr out with me anyway.

I probably shouldn't have gotten that 777, as I have a tendency to try and make them (the rounds) seat as deep as possible. I developed that habit after a couple of what felt like "ignition.. pause.. bullet fly..." things. hehe
 
Sjohns, in my 51 .36 I found that the 15 gr. spout was the best with 777 because it didn't compress the powder. 777 was way too picky for me. I have been using American Pioneer and Pyrodex P since I can't get Goex locally and I don't have the $$$ right now to order 5 pounds online.
