CL,
There is also a lot of info on .54 smooth rifles (.54 obviously) and 28ga smoothbores (.55) here, and all of it should be very useable in your .56 with some very minor adjustments. Here is what I do with my 15/16" GM 32" smoothbore on a Lyman GPR stock:
Light: 55grs FFFG, 3 cards, 3/4 oz #6 shot, 1 card
Heavy: 70 grs FFFg, 2 cards, 6" jute twine nest, 2 more cards, 1.5oz #6 shot, 1 card
PRB: 80grs FFFg, 4 cards, patched .527" ball
I have a #4 buckshot (.24") mould also which is in the old "swan shot" size range, but haven't worked up a proper load with it yet so can't comment much there. So far, my best patterns are with 60grs FFFg, 2 cards, the jute twine, 2 more cards, and 20 of the #4 buck with another card to keep them from rolling out. But I still have a quite a bit of load work left to do before I settle on a buckshot load for this gun.
What size shot are you thinking for using out of this gun? I settled on trying to use #6 for everything as it seems to be a good compromise between large enough to work for most of what I need and still have a high enough pellet count to keep my patterns from getting too thin too quick. But Have heard a lot of good arguments for having some fine (say 7.5-8) shot and some larger (like #4-5), but being stubborn, I try to test things myself instead of following the lead of smarter people than me who have done a lot of testing to know more than I do. :bow:
