Rick as a trapdoor owner and soon to be shooter I am curious as to what loads you and Wild Bill are using in your trapdoors to utilize the trapdoors odd barrel config 3 grooves and lands? I have a 1879 in great shape and real good bore with the type 4 1879 rear sight I will be using at first and have all the parts to put together one for just shooting it is a 1886 barrel/receiver and lock plate also the buffington rear sight am preping all the parts for bluing and also some stock work. Right now for my first try out I am using loads of 68gr of Old e with the BACO 460405HB bullet WMLR primer and crimped as per Spence's book.
This gun is an heirloom hand me down from my grand father and great grand father it is a very nice rifle.

AJ,
Wow, that would be great to have an heirloom trapdoor like that. First a disclaimer, I am new to trapdoors and that was my first shot at 400 yds. Surprised me.
Wild Bill and I both started with the Lee 405 gr gov. HB mold and both using GoX2F . Bill does really well with that bullet and mine shot pretty well with it also. The 84's according to Wolfs book were designed to use the 500 gr gov. style bullet. I think BACO has some similarfrom the same source they get their 405's that you are using, that may be a good place to start. Have heard some good things about guys using the old standard Lyman gov. bullet but mine throws one that is just a little small for my trapdoor. I have a Lyman postell that I "beagled" sp? out to a smitch larger diam. That is what the target was shot with I believe. I am going to try doing the same to the Lyman gov. bullet and see how that shoots. I need to slug the bore also.
I did paint the front sight white so it shows up better on my black gong.
I also am going to try casting some of the Lee 405's in maybe a 30-1 alloy, I think that may help with those. So I have more questions than answers
I used CCI BR2 primers because that is what I use for everything, eliminates one variable for me when working up a load. .030 vfw. Compressed to the bullet seating depth I wanted. Approx 65 grs.
Just getting started on trapdoor loads
