As the OP, here's what little I've had the time to determine so far.
I nixed the use of the heavy bullets so my unscientific trial consisted of shooting a box of five shot groups with Federal GMM SMK 168s, Hornady Match loaded with A-Max 155s and 168s and Hornady Match BTHP 155s and 168s.
I'm not the greatest shooter in the world but I felt pretty good on that day and with my PA FFP 4-14x44 cranked up I think I shot just about as well as I'm capable of. The 155s gave me consistent 1.5 to 2" groups and the 168s gave me consistent sub 1 to 1.5" groups with negligible difference between them.
I decided for the time being at least to go with the Hornady BTHP Match 168s being the least expensive of the three.
I now have 80 Hornady cases that I'll load with 41.5, 42.0, 42.5, 43.0 and 43.5 grains of IMR 4064 using the same ogive to base OAL used in the commercial ammo as a starting point. Using the OCW method I'll determine the load that I like best then I'll fine tune the OAL using a couple of .005" increment changes.
For my very limjted purposes I'm pretty satisfied that this method will give me a load I can be happy with.
