Well gents, iīve gone and bought me an old Kropatschek which is one of the "later" ones intended for colonial use.
Hence it thus "runs both ways", BP and smokeless both.
That said BP is where itīs at to me, and i guess this is where this post takes off cause i want to dwell on what could be done as far as a slick/slider.
Have measured bore to .330" inches.
For those not in the loop, absolutely lovely rifle.
Now. Know iīve read it somewhere but canīt for the life of me recollect - twist rate of it. Recall it being "modern" though and taking the smaller caliber into account. 1:10 or there abouts.
Brass i make myself from 348Win parent casings, very easy to perform. Use a three stage setup and anneal brass beforehand. Dies used is for starters the LEE 8mm Lebel, followed by RCBS "reform dies" and in turn RCBS FL loading die set.
Then fireform before going any further. (Ie shooting blanks)
The original cartridge was either patched or very early jacketed. Ie; very soft jacket, be that as it may.. PP.
For reference.
I shoot PP 45īs and have at least reasonable success doing so. On this though i donīt even know where to start TBH.
Point here being that over here in Europe at the time many a rifle was handed boolits of lesser diameter than rifling dia and was expected to bump, to a reasonable degree.
Thatīs however not how we do it PP today? In essence most used are setup as bore-riders to my knowledge, and this can certainly be handled in this case too.
One of the aspects to take into consideration here as i regard it being rifling depth, which is excessive by todays standards albeit still not on the same level as the very early bolt actions like the Mauser -71, the Chassepot Mle 1866 or Gras Mle 1874.
Ditto on that one, sry to say. Got the numbers on a note at the shop.. and write this on my laptop at home.
Regardless.
Paper i normally use is 6/100 of a millimeter thick uncompressed. Ie; approx 2,5 tenths total on diameter IOW.
FWIW we CNC cut all our own molds why as far as design the skyīs the limit really, while it being a slick.. nose ogive mainly i guess?
Boolit weight weīll try and keep around the stock approx 250 grains. Ie; a rather "tall" boolit all things considered.
Have taken a look at whatīs out there but canīt really say i grew all that much wiser from it.
Any ideas as where to start apart from the downright obvious? Bore rider in this case too, and let the paper handle obturation?
Any qualified ideas on the matter would be REALLY appreciated gents.
