Quote:Pictures are pretty, but I'm one of those old foggies who goes by what prints on the target. Have tried LP primers and over primer wads and all sorts of combinations these past 3 years.
SS, no argument that "what prints on the target" is key respective to the load, including the primer used, the quality of the powder and how it is compressed.
But the brisance of the primer that starts the whole ignition chain to deflagurate the powder column is also a key.
Reading this issue of the SSRJ, a 2nd place score (193 out of 250) shooting 100yd offhand German ring target caught my eye:
Presume 1948:
Quote:Guy Burch, Maedonia, ILL - 193 out of 250 with a Pope Union Ballard 32-40 using full case of Schuetzen powder and blacl powder primer, 196gr Pope bullet.
It was 'the black powder primer' that interested me ...
These primers were manufactured for with a very low brisance that was compatible to ignite BP properly. Such primers are no longer made because the shooters of semi smokeless & smokeless complained that BP primers did not ignite these powders. So with the the new nitro based powders and BP shooters converting to it - BP primers faded into history. Now with the re-interest shooting BP in calibers created for this powder ... folks are searching for primers that don't 'whack' the grains and ignite the column for better avg fps and SD's.
My LP primer of choice in addition to BR2's is Federal GM150M
PS: Very familiar with Cumberland Riflemen having lived 20 minutes from the gate. Too and including working the 600yd risers in water up to my knees before the reconstruction. I shot my 1st BP rifle rounds there one day ... A used H&R BC and was dumb as a door knob. A Big Lube bullet with 52gr of Triple 7 - after 15 sighters at the 100yd - 5 rounds shot at 600 in 90+ heat & mirage resulting with 5 holes in the 7 ring. 5 3/4 x 1 1/2 with 3 holes that could be covered by a silver dollar. Dan witnessed this target never to be duplicated again!
