Me?how do you like those grip's and how do they fit on the gun is the fit good thanks
http://www.trackofthewolf.com/List/Item.aspx/807/2Looks so far as all I'm asking but, getting great information! Next, where can I get stainless replacement nipples for my ROAs?
This is a quick update concerning the use of heavy hunting bullets with BH209 and small rifle primers in the ROA using Doak's capsules.
I've been trying to get a consistent accurate load for deer hunting with the ROA using the black powder substitute Black Horn 209. After going through at least a dozen combinations, I found one that may prove to be what I'm looking for.
This target was shot with:
255 gr. hand-cast lead flat-nosed bullet
20.0 grains of BH 209 by weight
Remington # 7 1/2 small rifle primers
Distance 35 yards with 2-handed hold.
First shot was low at 6:00, next 3 shots measured 3/4", last shot just cupped the upper edge of the target at 11:00. Last 4 shots = 3" group. All 5 shots = 6 1/2".
I will try another load of 20.3 grains but that may be all that I can fit in the chamber using the 255 gr. bullet.
I have a conversion cylinder for my ROA that I occasionally shoot .45 Colt loads using up to 8.5 gr. of Unique with a 255 gr. SWC. I usually shoot hand cast 255 gr. pure lead FN bullets in a Starline case with 22.2 gr. of BlackHorn 209. I only have one ROA and see no real purpose in using it with maximum .45 Colt loads. I have a Blackhawk in .45 Colt for that.CAUTION: The following post includes loading data not recommended for Ruger Old Army. USE AT YOUR OWN RISK.

Since you have Doak’s adaptors so you can use standard primers, would be OK to use standard loads for 45 Colt, max pressure 14,000 PSI?
If I remembered correctly (I have no caliper at home today), ROA has wall thickness between chambers .065”; this is the same thickness as on full size NM BH in 45 Colt. According to one old article, ROA cylinder was made from the same steel as cylinders for other Ruger revolvers. If this is correct, in that case standard loads for 45 Colt shouldn’t be problem, but under one condition; after bullet is pressed in, powder space must be at least the same, or larger than in 45 Colt case for the same bullet and the same load.
OK. If we're talking about using smokeless loads w/primer capsules, that's not a good idea.
It has nothing to do w/the quality/strength of modern steel, cylinder wall thickness, 14,000 psi., or etc., etc.
The entire issue relates to the nipple threads at the rear of the ROA cylinder(s). Hot, high pressure smokeless gasses will fire-cut thru any threads, let alone the 12 -28 fine nipple threads, and blow out the nipples/capsules, from thread failure. Maybe not at first, but the temptation to use more powerful combinations is tuff to resist. My advise, whatever it's value, would be to not even go there w/smokeless.
The brass cartridge case solved this problem by making an expandable seal, of the case wall, against the inside of the chamber, not allowing any gas to escape and fire-cut it's way to the outside.
BP can't develope the pressure & heat to fire-cut. Although I have seen a poorly fitted nipple blow out of a percussion rifle using BP. Lotta racket & disappointment over that incident...

Hey Onty ~
Nice drawing! I noticed that there are NO THREADS at the rear of the cylinder!
We're talkin' about makin' a complete replacement cylinder here. Where the primer cup makes the pressure seal.
I'm not set up to make that beautiful arrangement. I don't have enuff machinery & funding to take on that wonderful project. I wish I did! And I see a way to improve it, too.
What's keepin' you from makin' it?
Kindest Regards,
Doak
Now that's an interesting piece.Just wanted to show off my just finished, hybridized ROA. The cylinder is a Classic Ballistix. That cylinder locks up tight and a .004 feeler will just fit between it and the barrel. I'll get it out to the range next Sunday.
