I have a portable bench I use and a portable target I use at the deer lease. If it’s a new scope-rifle set up, I use a lead sled to get on center and an inch and a half high. I then use sand bags to double check shooting on the sled. Year to year with the same scope on the rifle, I use bags to make sure it’s still on.
It seems my rifles stay on since I went to Talley bases and rings. I had always used the Leupold windage adjustable bases. No more.

I don’t like gun ranges anymore, too noisy, too many people!
