243 Weatherby 307 and 88gr Hammer Hunter bullets

Savage 10T 24" barrel with 7.7 twist. My reloading focus has been around shooting 103gr. to 115gr. bullets. Do not have a lot of rounds down the pipe, but I have found H4350 and Superformance both good powders. I do not have a good load dialed in yet. I started reloading for this rifle in Maine and now living in Florida I had to start all over again. Elevation and temperature made a huge difference in pressure, which affected accuracy and POI. Verdict is still out if I can get the 6CM to shoot as accurately as my old 243 Winchester? But, to be fair they are totally different twist rates. My 243 9 1/4 will not stabilize anything over 100gr. bullets.
