What am I Missing?

[Redrockhunter]

I have a custom 280ai that is very similar in performance. I have not yet found the right load.

My 7mag came with 160gr tsx as the preferred ammo. Lots of load testing only to find out that it likes the 150ttsx and loves the 160 accubond. All off the shelf.

Yea my 7mag throws them in a group that makes it look like i used open sights at 300 yards

Long bullets and slow twists don’t usually pan out.
