    Mold recommendations please

    Rifle is a .45-70 Pedersoli Down Under Sharps, 34" barrel, throat is .460", grooves are .459"

    One or two cavity, aluminum or cast iron. Must drop 1:20 at .460" to .462", no HP or HB styles. I prefer lots of lube groove for long barrels, my usual lube for boolits I cast is LBT blue soft. Purpose is strictly ringing steel at 100-300 yards. Loads will be smokeless. Please provide specific mold numbers as some makers have dozens of designs.

    325-375 grain weight range

    400-450 grain weight range

    PS- with .459" commercial boolits, hard (Lasercast) or soft (9 BHN from a friend) this rifle leads badly. Badly is defined as fire 20 rounds then push 25-30 grains of lead out of the barrel. Yes, I actually weighed what I pushed out it was so bad.

    63/37 Sn/Pb is a terrible boolit alloy but its other use pays the bills.

    If you take up powder coating, you can easily add several thousandths to a regular mold's boolit dimension. (** different powders add different dimensions)

    A friends 45-70 needed .461 fodder

    My go-to starting boolit for .45-70s is the Ideal 457124. Nominally, it’s 405 grains, but it seems to vary between 385 and 405 depending on alloy.

    Other designs might edge it a little, particularly as ranges and winds increase, but it is never a bad starting point for ranges out to 400 yards. I’ve cast it with everything from pure lead to range scrap and it’s always performed well.

    I like your handle. Did you work at Redstone?

    Thanks. Any idea what diameter it drops 1:20 alloy? .460" is my absolute minimum.

    I used to work at NASA Goddard and retired down here.

    You could contact Dick Dastardly for one of his "big lube" molds.

    Mine casts around 0.459Ē IIRC. Donít know what the newer Lymans cast at; you could call Lyman and check. A custom maker ought to be able to cut the cavity at the diameter you need.

    A custom maker will cut the mold to size according to the alloy you use. Change alloy, change diameter. Tom at accurate will ask you to specify your alloy.

    Been a busy week with garden canning, casting .30 cals and making thermocouple mounts for a PID. Meanwhile I managed to get an Arsenal 330gr and NOE 396gr (PB abd GC cavities in one mold) to try.

    Look for a quick & dirty thermocouple mount post later today. No cutting, no drilling just a few easily available parts, one bend, white vinegar soak to remove galvanizing and a little cold blue to prevent rust.
