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.

    I hope these get picked up by Walmart. I like the Federal bulk pack and they are fairly consistent for cheap fun and CCI Mini-Mags for light hunting but it’s always good to have options.

    Hello. Question, what situations or conditions are “hyper velocity needs”? Thanks.

    • Kerry, the hyper velocity gives more power when hunting.

  • “Aguila already holds the record for the fastest 22LR cartridge on today’s market with their Super Maximum cartridge that launches a 30 grain bullet at a blistering 1700+ ft/sec.”

  • Any idea on the price? Will be interesting to try them in my P22, it seems to only like CCI.

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

    It used to be “333”, it’s nice that they added 222 more bullets to the brick, IMO! My 10/22 and Browning Camper eat this bulk much more reliably than Remington fodder. Intend to keep about 3000 rounds in my ammo stash.

    I just picked up a pack of that 555 round stuff at a Walmart near my friends house, on the other side of town. Totally didn’t expect to find any .22LR, much less a bulk pack. I snatched that thing quick.

    Some people are reporting issues with these, so we’ll see how it goes. The Federal stuff shoots reliably from my T/C R-55 Benchmark, but accuracy is pretty low. I’m not expecting anything better from the Winny stuff, but who knows? 🙂

    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.
