338 LM Ackley Imp Loads

[duster]

Just getting started with this caliber. I am primarily interested in loading the 300MK.
Would anyone care to offer some of their favorite loads?
I have Lapua cases and a 32" Broughton 5C barrel.

I'm on the same boat but, here's what I gathered so far. For 300 grain SMK... 94 grain of H-1000. Went out this morning fireforming brass using 250 SMK and 94 grain of H-1000. Here's 2-3 shot group at 100 yards.

Here you go: Some of this is old information but not much has changed except the barrel is now 3" shorter.
