Winchester Hyper Speed HP and new 555 Round Bulk Pack

Over the past year Winchester have been doing a major update of their .22 rimfire product offering.

The new Hyper Speed HP load is a very hot load that matches the ballistic characteristics of the CCI Velocitor round. The Hyper Speed HP, like the Velocitor, features a copper plated 40 grain hollow point bullet. The bullet has a published velocity of 1435 fps at the muzzle, which works out to be 183 ft-lbs of muzzle energy.

A significant difference between the CCI load is that is will be sold in a 100 round box, rather than the CCI 50-round box. This suggests it may be quite a lot cheaper that the Velocitor. If it is, I will defiantly consider switching to this for my hyper velocity needs.

Winchester are also introducing a 555 round bulk pack, giving it a slight edge quantity wise over the Federal 525 and 550 bulk packs.

The bulk pack features high velocity (36 grain / 1280 fps) rounds with copper plated hollow point bullets. Nothing fancy.

Overall I am quite impressed with the new offerings from Winchester. I don’t think there is much else they can do as far as rimfire ammunition is concerned.

    The 555 ammo does not feed reliably in either my Ruger 10/22 or my Ruger 22/45. Since I don't have any feeding problems with ammo that is either round or less blunt, I believe the feeding problem is caused by the tips of the 555 bullets being too blunt.
    I won't buy another box of 555 ammo unless Winchester adopts a bullet that is less blunt.
