These are specially made 41 Swiss brass cases from brand new Starline 50-110 WFC brass cases:cut,annealed with AMP annealer,formed using Lee 41 Swiss full length sizing die,trimed with case length 1.665”(you can always trim the case to your desired length anyway),cleaned off lube then annealed once more,allowing you to load Lee C430-310-rf cast bullets or Matts bullets 430-280 rf to overall length of around 2.2”(observed that feeding reliably with loaded ammo OAL length between 2.180“-2.220”),feed from magazine and,extract and eject reliably.
The neck id will be around 0.421'' using Lee 41 Swiss full length sizing die, the trick to load these non-heeled bullets for 41 Swiss successfully is to size the bottom part of the bullet with 0.419'' sizer, upside down to the first grease groove from the bottom and top punch it out, then you can hand seat the bullet, use Lee 41 Swiss seating die with seating stem removed to give the loaded round a very firm and consistent crimp at the first groove from the bottom ( the seater will clear the bullet instead of the case mouth), by feeling that the case mouth brass is crashed a little bit ( it is ok that the bullet might be turned by hand inside the case mouth after crimping, but it would be firmly seated, won't be pulled out by hand),don't go too much,too much crimp might cause the case mouth bumping up too much and you might encounter difficulty to chamber especially with those Vetterlis with tighter chamber.
The 10-shot group was shot at 40 meters indoor range.
18 pcs once fired,52 pcs twice fired, all decapped,cleaned,AMP annealed,then sized,cleaned again,ready to load(checked that there was no case length growing).
Asking 8$ each+shipping or 560$ shipped to provinces for all of them.
FYI only, use it at your own risk: I found using the recommended charge from the internet of 11 grains of Trail Boss to be around 2200 fps and kicks hard,eventually I reduced the charge to 7 grains of Trail Boss to achieve around 1400 fps, very close to Vetterli designed velocity and very mild and pleasant kicks, no grease cookies, no wads needed. I rendered that the 11 grains of Trail Boss charge was gained from improperly reloaded rounds not using heeled bullets and not getting proper crimp.
Minimum 12 pcs cause the tube magazing will hold 12 rounds:).
