Powder burn rate Vs. Bullet weight? And 7mmSTW 168gr berger loads?

I am in the process of figuring out a new load for my STW and am about to make a drastic change in bullets. Currently I shoot a 127gr Groove Bullet that is no longer made. I am looking to go long range and have ordered up 300 of the 168 Berger VLD hunting bullets. Currently I am shooting Reloader 22 and I am not sure if I need to go faster or slower powder to move to the much heavier bullet? I am guessing slower and am considering using Retumbo. I have H-1000, Retumbo, and RL-22 on hand that I can test with.

Any pet load info that you may know of for the 7MM STW with these bullets would be much appreciated. Thanks!
