Much smaller. Cut a 243Win down by about 1/3.
I think I used to run about 27g 2208 in mine under a 105 VLD.

Great shot and a fine looking hare too! One of the few times I've seen 6mmBR do anything other than punch paper ha ha.
Bit secretive on the mix now LOL
it was intended for 105-107g
running a 108g burger well
pushing around 3000
im between .223 .243
The 243 WSSM yields somewhat faster velocity for the same bullet.
The 243 Winchester and 243 wssm are close enough that it would be hard to notice the difference.
The BR is much the same, runs small primers with a max of around 32g powder.
BR has a far better barrel life.
Ill let you know how it goes on Fallow shortly.:wtfsmilie:
It sounds good as. Should be a standard factory caliber.
Great Hare!:o
Is it a single shot Barnard action with a Trueflight barrel?
What sort of accuracy do you get from that beauty?
shot my first sika with one, cool cartridge
