I have an extra Whitworth action .375 and am wondering if anyone has used this platform for a 404J conversion.
Please let me know about
Length of the box
cartridge stacking
Feeding issues


I am hoping to use the same .375 profile for the stock and barrel inletting ease but don''t know if that will work with the 404J. Will this create problems?
Any other issues you may have encountered.
