Sry for the delay on my behalf,but i had a real moronic setback...all me.
I fabbed a fresh chamber insert alright,this time out of regular SIS2172 "regular construction steel". It turns out it copes just fine too..
But. We were off to try the thing out,armed with approx 50 all soft bullet cartridges and in turn 50 alloy ones.
Starline brass,70 grains of 3F,an over powder card (out of milk carton) then a dry 36cal wad followed by a greased 45 cal one and in turn the bullet...
Set the rifle up in my new shooting bench and me and close friend Stefan went at it at 50 yards.. taking turns to shoot.
My bad.
My turn once again,we had fired like short of 10 rounds by now,and i felt something was REALLY amiss as soon as the hammer struck home.
Powder splash all over and i felt something pass my head violently
As in turns out,seeing all the jobs pulled,i must have missed on on torquing the nipple down and seeing its threads were so so to start with the nipple was simply ripped out of its socket,bottoming the hammer out in its travel to shear the tumbler spindle clean off!
Yeah well..that´s all on me and i´m an idiot...period.
Seeing that the hammer went missing me and a friend went down there a couple of days later to search for it with a metal detector,and lo n behold if we didn´t find us a hammer!
Headed straight back for the shop to repair the thing...
Uhu. Welded the thing back up and got it all ready for action again. Now just missing a nipple but seeing that these rifles use a regular 5/16-18 threaded one and that the postal services takes forever around x-mas and new years i...
..opted to turn one myself as a "make do" waiting for the ordered pts to arrive. Works just as well i guess,with a 3mm major inner diameter and in turn a 1mm through hole to limit backpressure per normal these days.
That said i´m going to revisit the range as soon as i can,figuring that what´s been pulled since the nipple turmoil might very well be the ticket.
Also fabbed a fresh "cartridge stopper" for the plunger setup/bolt. This time out of steel and with way tighter tolerances.
Going to be very very interesting to see how this piece performs next time up.
