Prittchets, here is a description of the accuracy I wrote for another place.
"Well I shot them (0.550" Prittchets) with the 0.568" Pritchetts today. Loaded as cartridges with 69gns of TPPH
Both did well but the 0.550"s doing the best, they were grouping tighter around the 2-3" mark at 50 yrds out of a PH P53 but there were about half a dozen wild flyers as well which were probably from deformed bullets getting them off the pins.
The 0.568"s were 3-4" and pretty consistent at that however there were odd ones out of the group, these bullets are tight to load with two wraps of draughting paper which is 0.003" thick with a 4-1 tallow-beeswax lube and I was getting inconsistent shedding of the paper patch and probably some skirt deformity when tapping in a tight one.
Looks like 0.550" is the way to go.
I will need to try and drum up some more support for the NOE Pritchett."
From well cast and consistently loaded bullets Minies or Pritchetts I will expect consistent 4-5" groups over 10 shots at 100 yrds, I have a short Minie that will better that but as it is so light it looses it much after a hundred.
I have some old figure of merit data from when I last shot these seriously using 0.573" Minies (a decade ago) and I am going to get more down range when I get a good 0.550" Pritchett mould and start comparing the F0M numbers.
Here is a link to the sorry French Prittchet mould saga in the unlikely event that anyone is mildly curious.
