Yes I had or did a 219 Zipper from a 22 Hornett barrel, Had a bit of
case sticking until I start useing 25-35 brass to make 219zip,
Sure did help sticking problems. Reason I went with the Zipper over
DW is I got 219 dies years ago, never used them.
Never have got a good load worked out, The best so for is 27.5 Grains
of IMR 4895, 52 HPBT sierra bullet. Us4e that last june at GBO
Pdog shoot, Did fair, Trigger pull was over 4 lbs.
Best of luck. Marv.
