    Triple 7 is a black powder substitute and like most substitutes it ignites at a higher temperature. With black powder rifles sometimes the flash from the cap has to go through a sharp bend or turn which can cause ignition problems. If magnum caps are not lighting your main charge reliably then useing 2 or 3 grains of real black powder with triple 7 on top of that will solve your ignition problems.

    CRV, in addition to what Donny said, be sure your rifle's flash channel is clear so the flame from the cap is not impeded. A pipe cleaner works very well to clean out any fouling that may have accumulated.

    Thanks for yours responce I used a air compressor and pipe cleaners to clean the vent before i went shooting.its hard to get real black powder in Denmark so I am thinking abouth using musket caps or a spitfire hot nipple.

    I have the same problem using Goex FFFG in a CVA .45 kit rifle. I like to run a cleaning patch down the bore after every shot and I think this is driving crud into the passage between the cap and the charge. I can get about 3 shots in a row without the cleaning patch but then it becomes really hard to ram the ball down. If I wasn't so cheap I would fire a cap off with an empty chamber to clear the crud out before loading it up. Hmmmmmm got 1000 caps coming in maybe I will try that.

    Try this - after each shot run a wet patch down to 1 inch short of the breech face, then back out. Follow with a dry patch. Then use a wet patch all the way down, followed again by a dry patch.

    Lots of extra effort, I know, but IF you're pushing fouling into the flash channel that's one good way to minimize or even eliminate it.

    The GPR has a patent breech - a smaller diameter 'combustion chamber' in the breech face. It may need to be cleaned out with a smallbore wire brush or scraper, at least .32 cal or smaller. If you haven't done that yet, try it.

    What Mykeal suggested should cure the problem. I took a slotted cleaning jag for a 7.62x39, drilled it, tapped it for 8-32, soldered a short piece of 8-32 rod to it so it fits my range rod. works well for mine.

    Misfires on muzzle loaders are not uncommon

    try changing the old nipple with a good stainless nipple , make sure to use anti seize compound on the nipple threads to prevent galling.
    although the cap is igniting the nipple port may be obstructing the charge preventing it from reaching the load if you have a reamer ream oit the nipple from the threaded end to open the port wider.

    It never hurts to hit the side of the rifle with the palm heel of your hand to help get some powder up in the charging port.

    That depends on how hard you hit it.

    Most critters - people, pets, etc- seem to respond postively to an encouraging pat on the back . Seems to gently, affectionately patting ole Betsy( yer rifle that is) might help. :D:

    all good advice. that is a quality rifle. there is a learning curve to shooting bp rifles.the more yu shoot the easier it gets. yu will learn a lot.load, slap, tickle, fire! yu can shoot bp all your life and never learn all there is to know.each particular rifle takes a certain thing to fire with regularity.
