I posted this in the centerfire section last night because I did not see this section, but here is my question?

I recently found a HS precision stock off of a 110 FCP .338 LM for sale and I was wondering if it would work for me. I have a 110 .300 win mag staggerfeed that I am rebarreling and turning into a long range rifle. I would like to use some sort of DBM. Could I use the Accurate Mag DBM that the stock is inletted for? Is there any major reason I couldn't do this conversion? What would need to be done to my action to convert it to a DBM? I have talked to Accurate Mag and a sales girl at CDI and they both said their bottom metal is the same for both .300 win mag and .338 LM. Is there in major differences between the .338 LM action and my .300 WM as far inletting is concerned?

Thanks before hand for any help.
