For good reasons; 5,1g round nose fmj bullet was/is very good killer for such big birds as blackgrouse and capercaillie. I have shot some birds with my 7x53R and noticed that this bullet is very accurate and flat shooter to 100-150 meter distances. Nowadays, when we in due course have some roe deers in Finland, is same bullet with bly nose very usefull. My friend has single shot Arisaka in 7x54 and said it´s very nice caliber for roe deer.
