It depends on the purpose. For deer/antelope, it is hard to beat a 139/140-grain bullet under Re 22 or IMR7828. I prefer Accubonds, Partitions, and Hornady Interlocks. I load them to around 3100 fps.

For elk, I use a 160-Partition under Re25. Re33 works well, also. I load them to 3000 fps.

If I had to have a one load only, I would go with 160 Partitions.

A number of powders will work with the 7 mag. It depends on what your rifle likes.

You did not "seen" anything, you "saw" it.
A "creek" has water in it, a "crick" is what you get in your neck.
