Something to consider... the Savage barrels I've had in .223 are throated pretty long. If I want to seat a 69gr SMK in my latest 1:9 LRPV, I have to go to a 2.340" COAL (1.943 OAL) to put the bullet at the lands. I've never had a 1:7 Savage .223 barrel (I think these are only avail. in LS - correct?), but I would be a bit curious to know if the 1:7 had any longer throat (since it would be targeted more toward the longer/heavier bullets). If it did, I think you'd possibly be giving up some seating depth and may need to avoid seating the 69gr SMK to the lands (and I have found that this typically works the best when using the 69gr SMK in the Savage 1:9).
Just a thought...
BTW... the bullets I have tried (and looked at) which are 75gr and higher ALL recommended 1:8 to 1:7 twists. I would ALWAYS go with their recommendation as they know considerably more than anyone else what it will take to get the best performance from their bullets.
