" 11's fall off. There is a way to crimp them and of course roughing up nipples. "10's misfire too much. I hear that reannoctors are using 10.75 caps. After searching internet -most info is vague. Are they available? And(if so) Where?

cap height

some brands of caps are taller than others. My ROA does well with Remington but occassionaly CCI fall off.
 
"10.75" is often the 'size' attributed to percussion caps made by Dynamit Nobel, aka RWS caps; that's probably because they have the number '1075' (without the decimal point) on the label. They compare to CCI and Remington caps as follows:

By the way, despite the three decimal places those numbers are not claimed to be highly accurate. Others have gotten different results, although the relationships between sizes and brands is preserved.
 
I loaded a 61 uberti navy w/ 20grains goex. I had already cleared chambers w/#10's and replaced w/10's. they were seated and stored for 4 days. I fired 1 and the next 2 didn't pop. Anyway after those 2 did on 2nd go round. One would not. I pulled it off w/needle nose plyers and put a#11 on and fired it out. After cleaning I noticed bluin was a rainbow of colors. Those cci caps are hot but are not dependable for me.
 
Its 2 years old. And yes heard of those nipples--gonna order some. I saw a guy in the sventies break down his Rem- he soaked his nipples in everclear and never put oil on then but took a pipe cleaner and lightly coated the cylinder threads w/ A/1---I noticed nipples seemed to be sliced w/ cutting tool that had small and sharp burrs. He said that kept his caps from falling off. Ya'll do that?
 
I use 10s on my colt and remigton 44s and 11mags on my dragoon. only problem I have is when the caps fall in the guts of the gun. If 10s misfire use a different brand.
 
Hardy, That Everclear comment reminds me about my ex-wife, but that's
a story for another place and another time.
 
The CCI & Remington caps are not equivalent in size. A rough order of size to fit any particular nipple (going from tightest to most loose):

CCI#10 smallest
CCI #11
Rem#10
RWS#1075
Rem#11

The CCI#10s don't fit any of my guns, they are too small.
Half my guns will take a CCI#11 and half will take a RWS#1075 but ALL of them take the Rem#10. The rem#10 is taller and easily flares as it is seated on a wider variety of cone shapes & tapers. If you have loose caps, just pinch them out of round and seat them but a proper fitting cap is best. Most of my ASM, ASP & Uberti guns have STOCK nipples that take the Rem#10. If not I get the stainless steel replacement nipples that fit the Rem#10s.

Tresos are Spanish made. The Treso nipples are very good after trying them.

Uh, No, they're made right here in the good ole USA by Treso, Ltd, which is the manufacturing division of The House of Muskets and is located in Pagosa Springs, CO. Treso uses Ampco™, a proprietary aluminum bronze alloy for their percussion nipples.
 
Thanks guuys--I guess my wholesellers donmt carry tresos --gonna check into it. I also thought that roughing and scratching that i mentioned earlier might be dangerous since a sharp burr could ignite cap when placing. What do you think?
 
I chuck mine up in a drill and start with 320 and end up with 1500 grit
wet-dry paper. Mine look like they are chrome plated.
 
Ok -- like I said- 10.75 caps don't seem to be available but in vague posts they are. It's like the twighlite zone . Are they there to be bought?
 
Hardy - go back and read post #3 very carefully. 1075's are RWS caps made by Dynamit Nobel. Carried by many sutlers, including The Log Cabin Shop.

If you wish to carry Treso products, contact The House of Muskets via their web site: http://www.houseofmuskets.com/
 
Geez, an extra $25 for shipping! Not something you want to buy mail order if you can avoid it! I'm lucky, I guess, one out of five gun dealers in town actually carries them. Never had a dud.
 
Coupla thoughts

Shipping costs - The shipping charges of some of the mail order houses turns me off too. I would not want to be a small online retailer unless I really had a niche.

Squeazing caps - I have had one chain fire event in my life. It was in a 1851 pattern Sheriff which I was knowingly shooting with caps that needed to be pinched. I had good fitting round balls and schmootzed the chambers with bear grease. But the only caps I had with me were too big. This pistol shot fine through numerous rounds with the right size caps. But when I used the larger caps, I had a chain fire of the post battery chamber with the first shot.

My situation is not exactly like Hardy's since I knew my caps were oversized but shot the pistol anyway.

AND....I am not saying the pistol chain fired BECAUSE of the pinched caps. I will never know what actually happened.

BUT....I took from the experience the idea that pinching caps can permit a chain fire to occur from the aft end of the cylinder. So I don't pinch caps any more...ever.
 
I've only tried this on one revolver but I've just capped one nipple at a time and never had a chain. Maybe other revolvers are different.
