I got a "not found" on that url. So - this is ammo, not bullets?

The 8x56R ammo is mostly available only with 206gr. fmj's, not hunting bullets. The loose fmj bullets themselves are listed for sale at tradeexcanada.

Of course, they might shoot OK if simply reversed. I would not cut the nose off - even though Ackley said they could not get the core to spit out of such modified FMJ's. The reversed bullets were used as steel plate penetrators during the first war for shooting snipers behind such plates. Reversed and shot backwards would probably do for deer, bbear, elk or moose out to 150yards or so, if accurate enough - they just might be. Used this way, even steel cored fmj's can be deadly, creating massive cavitation coupled with unparalleled penetration, as anyone reading Harold Johnson's stuff about brown bears and his .50 Alaskan knows.
