Hi @Boxton
My A7 likes just about everything I've put down it so far. I've got a good load with each of the following: 150 ELD-X, 162 ELD-X, 162 ELD-M, 175 ELD-X and the 160 TMK.
2217 has been the best powder I've tried but I have also had success with 2213sc and 2225 as well.
All of those are at mag length as well.
As for charge weights, I've had variations in batches of 2217 so I won't give you a charge weightstart low and work up, you'll find sweet spots easy as.
