the Gevelot 11mm Gras Nitro load have the V0 of the original old blackpowder load no doubt for go with the original iron sights what is important.the older black powder breech loading rifles were not strong enough for more pressure/power.

like the Orman forestry carbine because of the hidden teutonic look
