I've heard those fatal "tenths" are kind of tricky without stating the temp. at which measured (wink). The 1/4" of hull rolled down to a double walled 1/8" over the top card wad of the typical bp load sounds good except that I just measured overall loaded length of three of my bp shells which are loaded in expended 3" plastic hulls previously carrying Brenneke slugs prior to the season of the rack, cape, and vennison. All were loaded from an adjustable scoop powder&shot measure and have a "typical" 1/8" over powder wad, 1/2" waxed bd. wad and a thin over shot card wad adding to the stack hgt. Excess hull was trimmed off with a utility knife against a 1/4" thick brass washer lying atop the load and roll crimped. Here's the OA lgth. nos.:
2 1/2 dram + 1 oz: 2 7/32"
2 3/4 dram + 1 1/8 oz: 2 7/16"
3 dram + 1 1/4 oz: 2 9/16"
Maybe I am an ignoramous with ADD as it appears to take, in my non-hypothetical 3-shell sample, a lot of propellent and payload (more than I'd want in a gun proofed to 3 tons)to get to 2 5/8" overall lgth. Conversely, I have seen ragged pie crimps on hulls holding nitro and plastic from some of my old residenters. What can it all mean? I think it means that the stuffin means more than the thing in which stuffed certainly (except in the case of super-steep cones), but may also mean that the problem with all the arguments is too much fiddling with the marginal example. A 3 1/2" magnum stuffed into a 2" chamber (if you could do it) would sure tell us something about extremism, would it not? Too much of absolutely everything!
