Jerry- Nice looking NEF you have there.When I say large primers
I mean BMG primers. Rob can make rims or completed cases
and is selling them now. Rims aren't cheap, I think they are
about 5 dollars..Contact him at email given above.
Loads -With long case, bmg primers, you can use 240 grains
of slow HBMG powder.Start at 240 and if it extracts ok, work up.
Always fill up spage with seal and wads.Cushion wad is good.
Here is a Rob project that will make you drool.
Rob on AR is building a 12GA FH double on a Zabala Double
10 gauge frame. It has the Greener crossbolt. He cut off
barrels to make a 4" long monoblock double to screw a
pair of heavy 12ga rifled Pacnor barrels into. He reamed out
monoblock section and threaded it. His barrels are
1.116" at the breach, .97" at muzzle and 22" total length.
Barrels threaded into monoblock with a 15/16" x 32 thread.
In the pics it is partly done and he will put in the ribs
and integral sight rib and regulate for accuracy.
It will be about 14.5 lbs when done he says.Ed
