IMHO, a 2-1/2# trigger pull on a 7lb rifle is unsafe - as you have fortunately found out w/o harm to anyone.
I would definitely not load it again, until I had pulled the buttstock off for a look at the sear engagement & repair it.
Most likely someone has reduced the engagement too much by far, requiring the installation of a new sear to remedy the condition.
It's quite common to store those Model 99's in a decocked state via opening the lever, pulling & holding the trigger back while closing the lever slowly - but I've never recommended doing so with a live round chambered.
