I have one of Bo's Grand daughter's:



That Bo pooch gets around, no?

I'm surprised nobody mentioned that 2 3/4" shells loaded to specs that fall below the service proof for the gun are fine to use. I did run the Winchester low noise low recoil 7 1/2 loads in my MacNaughten, with good results on grouse and woodcock, back in the day. That tip came from Kirk Merrington, but, it would be wise to find a stouter load, or, gun, or, both for pursuing ditch parrots when it is really cold.
I don't think Kirk ever hunted pheasants in late December in MN, or, the Dakotas.

The older I get, the less tolerant I am of going on Easter egg hunts for ammunition.
French triple proof, at 70 or 75, or anything else out of Europe at 2 3/4", or 3" is my friend.

My 2 1/2" chamber guns are all gone.

Best,
Ted
