.44-77 and paper patch?

[J.B.]

There's a lot of calculated ... even guesstimated measurements put forward for my mould but they are based on practical experience ..if not chamber casts and gauge pins. My cases come out with an outside case measurement of around .467" . If flared too much...say .469"...they won't chamber and you can feel the case mouth grabbing the chamber. At .468..you can feel there is no play in the neck of the chamber when you try a case. Its not a pp chamber...but its certainly a snug chamber..which is great. Case neck thickness varies from .009 through to .011.. depending on lots and brands...or who it was purchased through. I've got some ultra fine cotton paper through Shiloh that I purchased over 30 yrs ago but there's precious little of that left. Even have some lube sheets from back then too. Wrapped in grease paper and away from the sun...they still haven't dried out. With Seth Cole yellow... I add about .004 to the diameter...with white...its more like .005+. The BACo paper is thicker still. I've worked on this mould using both S.C. paper options and hopefully this will play out. I've a feeling I may still need to size 'some cases'.. but only by 1-2 thou to maintain some kind of hold on the projectile. Bring it on.. Too much time waiting between shoots means I get itchy fingers and re-invent the wheel again... and again. Bit like having no rifle hey Jim ?
