I have read, heard ,over again that the ruger old army can be loaded up to match the performance of the 44 mag,with 777,can anyone tell me the actual results of chronographed 45 grain loads of 777 and buffalo bullet 190 gr or lee 220 gr bullet.thanx for any info:cool:
 
they can break 1000 feet per second as I recall with a 200 grain? (i havent weighed mine) round ball. But nowhere near the velocities of a loaded up 44 mag.

You wont get 44 mag performance.

Use the search function for ROA on this forum there was a big thread on this subject

edited to add: My bad you already asked this question before so you've probably seen the old thread I mentioned

The round ball is more like 144 grains.

That is correct.
You can calculate the weight of a lead round ball in grains by cubing the diameter and then multiplying that by 1503.

.457 X .457 X .457 X 1503 = 143.45 close enough to 144 for my purposes.

Getting 45grs of 777 under a 190 or 220gr conical is the problem. You would have to bore the chamber deeper. At best you could approach .44spl levels but not even close to .44mag.
 
Even at 40 grains of 777 under a round ball you are pushing it since 777 is not to be compressed like BP is. Like madcratebuilder stated you'd want to get the chambers bored out a bit deeper. With 40 grains and a round ball you may be able to get a felt wad in there, as I recall, but 45 grains of 777 in an ROA just isn't do-able.

.44 Magnum it Ain't!

Don't get me wrong...Ruger made a nice revolver--about the size of a L-frame S&W, not the N-frame! Not enough room in the chambers to launch that ball fast enough to give you anywhere near the power factor of a .44 Spl! My .44 spl. rounds are factory Magtech 240 grainers. They go out of a 4" test barrel at 761 FPS, so add another 30-50 FPS when shot out of my 8 3/8" Dirty Harry S&W Model 29! That's a power factor (speed X weight) of about 180 or so. Those cowboy loads make IPSC Major classification!

Smaller, lighter round balls may travel faster, but they don't have the mass.

As for 777, since it says not to compress it right on the label, it will never go in my guns, cause out of habit I compress black powder in black powder guns:eek:
 
SMOKIN WHAT?

WHO SAID ANYTHING ABOUT BALLS,I ALLREADY HAVE PUSHED MY ROA TO 1200 FPS WITH 190 GR BULLET=AROUND 600 FPE WHICH IS BETTER THAN 44.40 TERITORY AND THE GUY AT CLASSIC BALLISTICS GETS 1360 FPS 900FPE,WITH A 220 GRAIN 444 PATCHED BULLET,I JUST WANTED TO SEE SOME CHRONY RESULTS IF ANYONE HAD THEM THANX:cool:
 
you may need to have your cylinder bored deeper if you want MOAR velocity!

Trashcan lid sized groups will be the likely result :rolleyes:

moar velocity

I think my chambers have been reamed deeper,cause i can get 45 gr 777 under a 190 gr bufallo bullet,i dont have a chronograph yet,others report vel in the 1200 fps range with only 40 gr 777and same bullet,the classic ballistics guy said his gun load combo produces match grade accuracy .:cool:buzzards gota eat same as worms
 
maybe ur copressing

Yes sir the more the better seems like to me,Ive yet to see a damaged r o a ,and 777 been around a long time,as much as u can fit in the cylinder,said the ruger guy,heavy recoil means high velocity,beautiful smoke,and awsome accuracy with 190 gr buffalo bullets from muzzeloading emporium :D to hicstick,coffe can size groups at 50 yrds,is more like it,ive done it ,:D
