Gunsmithing 300 WM Reamer Recommendation

[Desert_Racer]

Would one of you gents point me in the right direction for a 300 WM reamer? I would like to run the 225 ELD-Ms at mag length, which puts me at 3.630" COAL/ 2.860" ogive. I also plan to try the 208 ELD-M's, which are 2.894" to the ogive at mag length. I believe Hornady recommends a .020" jump for the 225s.

I am trying to build this rifle in the Mk13 Mod 7's likeness (not an exact replica, but close). Thanks for the help.

My gunsmith used the A191 Reamer on my 300WM, and it is an absolute hammer with 215 Bergers. That is the reamer that was specifically made for the Mk.13 military 300WM ammo.
