Your Club is after my own heart, sadly a bridge too far I suspect.
I have several BAMM Milsurps, I suppose my favorite is my 03 followed by my SMLE NO.1 MK.III*.
Thy Smelly might have an advantage. with its 10-round capacity.
I have Krag's (carbine & a constellatory) and I do shoot them pretty well, but the 5-round and non-stripper clip box would be a disadvantage. My Artillery Berthier's 3-round Em-Bloc also would be out of the mix.
I had a Spanish 1916 Mauser converted to 308 and a suspected Lend Lease Eddystone M1917 w/ import marking, but I allowed them to go to new owners.
So, my issue is no likeminded folk in my haunts. I do embrace the BAMM idea, but the closest I'm aware of is Baltimore Ed's Club Outer Banks North Carolina @ about 800 miles
I load for 30'06, 303, 30/40 and the Lebel. (Berthier)
I sold the 308 dies with the Span. Mauser.
Sadly, I like to talk the talk, but I walk the walk.... alone.
