I shoot a Remington 1858 .44 revolver and a Rogers and Spencer 44.Although they both call for a regular cap-Can a magnum cap (#10 or # 11) be used without any ill effects?Will they insure reliable ignition?? Thanks. Ernie
 
I used the Magnum caps a few years ago, and the only problems occured in guns without a good hammer snap. They worked well in my Walker...I think I stopped using them because I didn't need the extra POP.
 
Aren't magnum caps just regular caps with more umph?

In my limited experience, standard Remington caps seem to have more pop than standard CCI caps and also go off more reliably because they are thinner.

I read that #10 caps work better on factory nipples on the Italian replicas and #11 are better on Rugers or using replacement Treso nipples.

That's been my experience. Remington #10 caps work flawlessly in my Uberti 1860 Army while CCI #11's almost always need two hammer strikes. Haven't tried CCI #10's.

CCI caps seem to use thicker material(copper?) and so are hard to pop and also hard even to pinch for me.

Remington and CCI both cost the same in my area($5 per 100).

What I do is use the CCI for practice(read: playing gunfighter around the house :p ) and save the Remingtons for actual firing (which I've yet to do :( ).
 
I stocked up on CCI Magnums some time back and I use them in both my in-line rifle and Pietta 1858 Remmy. So far (knock on wood), I've never had a Magnum cap not go off - but I HAVE had a couple CCI standards that either didn't go poof or looked like they wouldn't because there was so little compound in the cup that I just threw them out.
 
My experiences with magnum caps have not been pleasant. I've only used them on muzzleloaders and not revolvers though. The extra power seems to get the ball moving before the powder has built up sufficient pressure. This plays havoc with accuracy. I think magnum caps are best left to lighting hard to ignite fake powders, or guns that specifically need them. They might help a gun that has unreliable ignition, but a better choice might be to track down why it's unreliable and fixing that, rather than using a bandaid.
 
The magnum caps are designed to light off the substitute powders more reliably. CCI recommends theirs for that purpose on their website.

We’ve now expanded the line to four popular products. In addition to the #11, there’s the #11M with more power to light off replica black powders.

In my experience, the #11 magnum works well to light off H777 which seems to need higher temps in order to ignite consistantly. Never had any problems with them in my 1858 Remington (Pietta), I've gone through several hundred now. They are thicker than remington # 10's and #11's and a light hammer strike might not set them off...my guns don't have the lightest mainsprings so no problems with that here. :)
 
What about musket caps? Can they be used on revolvers? Do they ignite more reliably in bad weather?

Sometimes reliability is more important than accuracy.
