I have been loading for my 7mm Win 70 for about 5 years and it really shines with IMR 7828. I've worked up loads for 140 Nosler Balistic tips, 175 Rem Corlokt, and am currently working up aome 160 Nosler Accubonds. So far I have been able to find loads that group under an inch with all of these bullets using 7828, for hunting it doesn't need to be much better than that. The 140's load is flat enough to give a 6" point blank sight in range of 350 to 400 yards depending on your altitude. It sure has worked for me.
