was able to purchase a 1920 in 250 recently, is a grey rat that has been drilled on the top and had the muzzle threaded for not sure what. Picked it up with the the thought of rebarreling it my first thought was 6.5x55 but magazine limitations say it is a no go. 35 rem would be interesting as well and it will fit in the magazine wondering what you guys might chamber for with a rebarrel? Odd is good. Maybe a new 250 barrel with the faster twist will get the nod.
