Well that is what I am trying to say - that ammo is seriosuly underloaded. I could reload a 458 lott and get 2200 fps easy with 21 inch barrel. For the money they(Norma) could sell something like a Hornady Heavy Magnum load like a 500 grain Woodleigh at 2400 fps with low pressure... They commercially produce powders so it shouldn`t be a problem for them to blend some super propellant... Especially they have lots of experience in powder industry...
But now they choose to sell underloaded ammo for a huge amount of money just because Kevin Robertson is on the box...
Geez it is just too weak for dangerous game... and costs a whole bag of money.
