I am after the dimensions for a.375 Lee Speed magazine, not the standard 10 shot but the one in between the fish belly and the 10 shot, at this stage I convert No1 Mk111 magazines into 5 shot fish belly magazines,
these magazines are an exact copy of the original BSA/LSA magazine with the curve going across the width and length of the magazine, since making these magazines I have had a lot of interest in converting the SMLE magazine for use with the .375 round, this can be done by making an insert to go inside the standard magazine making it a flat stack configuration. If any of our members have converted SMLE magazines for use with .375 ammunition, your input would be much appreciated
