Posting this in case it helps anyone here...

I have confirmed by checking the key dimensions, a visual reference (see pix), and then finally the actual fit to the rifle's chamber -- it is true that a 22-250 AZoom Snap Cap works great in a 250 Savage, aka the .250-3000.



This is great, as I can't "hold back the trigger" on my Savage 99A to de-cock it like I can on my 1930's F model; so now I don't have to store the 99A cocked & locked...

Tight groups... And "snap away"!
