[Mesorah] kamatz katan at end of word?

[Michael Hamm]

I asked:
<<We may have discussed this already, but what is the rule, please, for
an unstressed kamatz at the end of a word followed (not with a makaf,
not with a mafsik) by a dagesh (not beged-kefes): is it a kamatz
katan?  (An example is in R'e, which we read today, 14:26:
v'aCHALt[a/o] SHAM.)>>

Many thanks to the three respondents (one off-list), who all said it's gadol.

K'siva vachasima tova.
