So it's taken me burning about 2 1/2 lbs of powder to get to this point, but I think I've maxed out my accuracy potential with the 45-70 (with this bullet anyways).
This is with my Pedersoli rolling block 45-70 with the soule tang sight. Twist on the barrel is 1-18.
This load shoots sub-moa out to 450 yds so far. I hope to try it out to 1000yd this weekend or next.
The cases are Starline cases fireformed to this particular rifle. The flash hole is chamfered with a Lyman tool.
I do not size the cases prior to reloading. I deprime with a universal deprimer and clean the cases.
Primer is a CC1 200 large rifle, BR2 primer works just as well too, but costs more.
Powder charge is 67.5 grains by weight of Swiss 1.5 fg black powder.
The bullet I am using is .459 and cast from the Lyman 457125 mold, and weighs 522 grains when cast in a 20-1 lead/tin alloy.
Bullet is pan lubed with SPG.
Max overall length to allow the cartridge to chamber is 2.94", so my reloading length is 2.93" to have the bullet .010 from the rifling.
Wads in the cartridge are a .02 card wad over the powder and a .06 unlubed veg fiber wad on top of that.
I use a compression plug to compress the powder to the depth where the wads on top and the bullet brings the overall length to 2.93", I believe it is .587 to the top of the powder column.
The bullets are simply pushed into the cases by hand and seated on the wads.
I hope this can help someone figure out their gun.
Here are the last 2 groups shot with this load. Sub-moa for both at 300 and 420 yds.
