54 yrs old.
I bought my 7MM RM in mid 80's. It's my hunting partner every fall.
150gr Nosler Partition Federal Premiums were my go to round until they became very difficult to find over the counter so I have been using 160gr Nosler Partition Federal Premiums for at least the last ten to fifteen years.
Early on it would have been chit house luck to find 7MM ammo in a small town in Montana. They seem to be more readily available now though.
The 7MM will be in the breaks again this year and with a little luck I hope to be dragging/packing more home to the dinner table.
