.25-25 Stevens
Posted: Wed Nov 16, 2011 4:58 am
Hello, everyone. I have been working with an original J.M. Ballard No. 3 in .25-25 Stevens. This rifle left the factory as a rimfire..probably a .22 short or long sometime in the 1880's..the action is cast-iron construction. Sometime in the far past, someone has re-bored/chambered to .25-25 Stevens..very professional job. action nice and tight, mint bore.
But since it is a cast-action, I have decided to use only black-powder. Cases are from Rocky Mountain Cartridge Co.
They are turned from solid bar stock on CNC lathes.
I have several original Ideal .25 moulds..various weights were cast using a fairly soft lead-tin alloy. Lube was SPG.
The twist is 1-12" so a 100gr. multi grooved bullet was used.
I am using Fed. small pistol primers, and Swiss 3FG.
The first few outings gave accuracy in the 2"-3" range. I had used Creame Of Wheat as a case filler over the powder charge..this was a big mistake..that filler grabbed the walls of the case & stretched some to .050"! One actually was torn in half. Never again.
Next time out, I useing 22.0 gr. 3FG Swiss, a "grease cookie" consisting of two 1/16" dental beeswax wads with a 1/16" wad of SPG sandwiched between..the rest of space filled with p**f-Lon filler. This gave a 1" group.
Next I tried 22.5gr. 3FG Swiss with above wads & filler...this put 4 into 1/4"..fifth felt off & opened group a bit.
I was running 1 barely damp patch thru after each shot..fouling soft and greasy.
Next I tried a du-plex load of 1gr. IMR SR PB next to primer & 22.0 gr. 3FG Swiss. This shot accurately, and left bore very clean..even in grooves.
I plan on experimenting more with these du-plex loads.
I made up a 36" brass drop-tube, and bullet seating is done with an original Ideal No. 3 tong tool.
This has been one of the most interesting black-powder projects to date. Cold weather has probably ended testing for this year.
