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

[Sako7STW]

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!

You can always checks for loads others use here:
12 loads available in 7mm STW with bullet weight equal 168

Just be sure to work up with care

This is a load that I found shooting 168 Bergers with 79.0 grains of retumbo out of my 7 Stw
