Have you tried any imr 4064 or 4895? I love both of these powders for the 243, it shoots well in several ( 5 ) 700's that I have loaded for and if you tweek with it , and I always do, you can get sub MOA if the gun and shooter are up to the task.
As for the 55 bt's I wouldn't recommend these for deer hunting, I love the partitions though and I do have some extras that I would probably sell in the 95 grains. The 70's would definitely not be a choice of mine but I thnk they would be ok for lung shots only!!! :-)
I have also used the 95 ballistic tips(bt) but they do some damage to otherwise edible meat.
Also when you load for the ENCORE check the OAL of the cartridge and see how far from the riflings it is, I love to stretch these babies out to where they are almost (but not ) touching, but make sure they aren't touching because sometimes you could have a lockup problem
If you play with the OAL you can get some real accurate handloads if everythingelse is right, but you have to play and that is the fun of reloading, trying to tweak out as mush accuracy out of your HANDLOADS ( I WEIGH EVERY CHARGE) as possible and then try to do better the next time :-D
