As I recall, Mule Deer recommended having the fore end NOT tight against the receiver. That was in one of his Rifle Magazine articles, if memory serves. That is how I have bedded my 99s. Three of my four 99s have the buttstock Accra-glas bedded as Ray says above. My fore ends basically just hang off the barrels. No pressure at all and no firm contact against the receiver. My 99F in 250-3000 has no modifications to the bedding other than to be sure the fore end isn't jamming in between the receiver and barrel. It shoots very nicely indeed with 87-90 grain bullets. My results with the other 99s are mixed.
Maybe Ray can give us a clarification on how he beds 99 fore ends.
