Any one know of a book or maybe some sites that have information on using small charges of smokeless to help ignite BP loads?
Have FFFg BP, and fair selection of Shotgun and Pistol smokeless powders.

    Don't do it. Dangerous.
    What kind of gun do you have, what kind of ignition, ie, shotgun primer etc?
    You can get this stuff to light off without using smokeless.

    What Allen said! It's called a duplex load, and can be very dangerous.

    I am using a BPCR rifle. Read a book several years ago, can't remember the name of it, but it dealt with BPCR-Schutzen matches.
    Stated that several of the top competitors in the early 1900"s used duplex loads to help reduce the fouling of the bore when using BP. Seems like they were using 2 or 3 gr. of Red Dot or Unique.
    Any thoughts on how well FFFg would burn when using a large rifle or large rifle magnum primer?
    Any suggestions as to a powder with a lot of bulk somewhere between 2400 and 3031? How much bulkier is SR4759 than 3031?

    Cautionary statements noted.
    Any one know the first name of the man Pope who was a barrel maker and rifle builder in the first half of the 1900's?

    Do you mean Harry Pope?

    That is him. Google does not return many hits on the man. Looks like the book sellers are in for a visit.
    Thanks.

    Powders used by Mr Pope are not much available these days.
    Go to
    http://www.bpcr.net/index-a.htm
    and search on "duplex".

    The usual thing these days is to put 5 - 10% of the charge BY WEIGHT, NOT VOLUME of something like Reloder 7 over the primer, and then a compressed charge of black, carefully loaded to NOT mix the nitro and black.

    This is a black powder CARTRIDGE technique, do NOT try it with a muzzleloader.

    It is an ADVANCED technique, do read up and be careful.

    Thanks for the link. Will check it out.
    Years ago, one could go to the library and find books on this subject. [:(]
