Is this brass too hard to form?
I currently use Winchester but am not getting case longevity.
I believe that RWS or Norma - (if available over here) may be a better quality.
Thanks for any feedback from you guys.

I have used RWS 22H brass to form 17A/H brass its a good brass but very costly i used once fired factory ammo cases saved from my Ruger 77/22H.
The capacity of R W S 22H brass formed to 17A/H is 13.9GRS of H380 with case filled to the top and settled them topped up and struck level
HDY cases 14.1gr but a big variation in case weight.
WW cases are 14.2grs
PPU are 14.5gr but the batch i bought had very badly formed flash holes.
R&P cases are 15.2gr and very cosistant in weight and the one i use mostly.
I use the Redding three step dies
Ist down to about 20 cal
2nd to 17 and trim to 1.397"
3rd to FL for fireform only and after back off the FL to only size half of the neck for future loadings
THEN ANNEAL NECK AND SHOULDER FOR FIRST LOADING but once formed i anneal the neck only after 5 fireings and am getting 15+ loads without any splits.
