Sir Ron, Wheew, got caught up in the crush yesterday doing my neighborly-s moving hay and firewood for old folk ahead of the bad weather on the way, many Thanks for posting the pics, this sport remains my sincere pleasure, the bullet used in the old '86 45-70 is a flat nosed greaser that weighs 496 grains at 16 to 1 alloy, the rifle is an 1892 year model with 20 twist half round barrel with black powder chamber, iirc the bullet leaves at 1264 fps over 70gr OE FFG.
I need to re-visit that 461 Gibbs/Selous/Seyfried experiment, cant remember what that bullet weighed after I had machine shop buddy turn the button off the stem as well as take 40 thou off the stem height, got the longest heaviest bullet I could get from that KAL mould, it's a dandy, also have a Paul Jones built 348 dia. 570gr AA Smerker mould, big creedmoor nosed greaser, that bullet is stupid accurate in my little 18 twist 45-70 Shiloh
