That's one helluva hollow point.
Any significance to the neck (crimps ?) ?

The MkIV and MkV rounds had what is casually called a Dum Dum bullet which was halted by the Hague Convention. The crimp is a 'stab' or 'jab' crimp which was a common method at the time.

The "Dum Dum" started with troop modification of the Mark II bullet.

The Mark IV was approved in Feb 1898 with a 215 gr cupro nickel envelope around a hollow point pure lead bullet at 2000 fps

The Mark V was approved in Oct 1899 and again during 1903/04 also with a 215 cupro nickel envelope around a hollow point
bullet but with an alloy mix to the lead, also at 2000 fps

Both the Mark IV and Mark V cartridges in my photo were manufactured in Canada

Thanks for the better details. The Dominion headstamps gave those two away. :)
What is the MkII...DF? Can't make it out for certain on my screen.

Test me on this. K C = Kynoch /Cordite?

Your right, if that Mark II was blackpowder it would be quite rare and without the Cordite stamp

2. Early 303
3. .276 (Pattern 13 rifle)

HA! I was on paper with the first five then flinched the easy ones off into the sunset! :)

I had to look to see when the Braves played the Twins. That was 1991, so the best in 25 years not counting a few really good ones in between.
I'm still halfway in between dreamland and a state of disbelief. Didn't think I'd live long enough to see it.
