What are some instances of large-scale production of caliber conversions on existing guns?
Ones I can think of
>after the problems with 30-03 and 7.5×54mm
>crappy Bannerman 30-06 conversion of Mosin-Nagant
>various 7.62 NATO conversions of M1 Garand
>Norweigan 30-06 Kar98ks
>Isreali 7.62 Nato Kar98ks
