Thread: Primer Leakage

I've got lots of experience loading for the .17 hornet, I had two, Both CZ sold one to GWH on here,
Get rid of the little gun its too prone to pressure problems, My results were similar, blown primers at starting loads.
I recommend, that you get a lb of CFE blackout, or N120, these are the stand out powders from my .17 hornet experience, H4198,(ADI 2207) and 4227 (2205) will be a little slow, but also less pressure.
Hornardy and resized .22 PPU hornet brass, are the same capacity, Winchester and Remington brass will have at least 10% more Capacity, this is were we run into pressure problems with .17 hornet,

I use a load of CFE blackout, 12.5gr, CCI 400 or WSR primers, Hornardy or PPU Brass, with a 20gr. 3650fps in a 20" CZ.
The 25gr V-max or Hollow point, at 3100-3200 fps are very effective, and there is no doubting a hit, the whump.
look after your brass, I neck size most of the time, Anneal when it gets hard, 5-8 firings, I am up over 15 firings now on sum Hornardy.

here's a couple previous threads for your info.
Saubier is the best place for further info, have fun and be very careful with little gun, its only 1/2 a grain between bang and boom.
