First, a warm welcome. Next, congrats on buying a fine gun in a great chambering.
Now, if you are talking about hunting, a rest of some kind is almost required. I've used trees, fenceposts and rocks with my hat as a cushion. But the best rest for me are my knees. I stand hunt with my Contender, and sit down with my back against something. When the shot comes, I draw up my legs so I can rest the gun atop my knees. It's almost as steady as a bench rest, and I've taken deer at amazing distances that way.
BTW, on the bench, rest the gun on the forearm, but keep the butt clear of anything solid or your impact will be high. I grip my shooting hand with the off hand right up over the base of my shooting thumb.
