McMillan advises that their stocks don't need bedding.

Some gunsmiths believe in bedding all stocks.

Do some of ya'll have experience with McMillan stocks with accuracy before and after bedding ?

I bed all my McMillan stocks. The inleting is very close most of the time, but I still bed. Try it without, then if it doesn't shoot, try it bedded.

I purchased a "internet special" stock for my Sako Varminter and discovered the recoil lug recess was too shallow, so I had to relieve it. I bed everything anyway so a small dab of Acraglas behind the lug and tang and I was on my way again.
