I believe it has more to do with bullet diameter then cartridge, Alex Wheelers #1 BRA reamer comes with a .244” FB diameter which doesn’t seem to be causing any trouble. I looked into fb diameters a while ago and from what I could find a fair few Smith’s go the .2438”.Which freebore diameter is best for a BRA or a Dasher?
Donovan , do you have a preference for the 103- 108 weight range VLD style bullet?Myself, for short & light bullets is the the only time I might consider a .2435" free-bore.
Good Luck
