I have been developing loads with the 143 grain in my 264WM and 260REM; 200 grain in my 300WSM and 212 grain in my 300RUM. Results are excellent. The 7mm and 30 cal 220 grain have not hit the market anywhere yet that I can find. Try MidWayUSA and get on the waiting list. I hope to put on of these bullets in a bear this spring.
