So I was drinking coffee with one of my gun buds and we got to talking about dialing in accuracy. He was having issue nailing down the 10 ring on his AR. I was surprised at his approach. Bench it good, the fire off a round, walk down, measure, return adjust, repeat. He told me he has always down it that way.

I on the other hand take a different approach. I too bench up and send 5 rd downrange. I go measure throwing out the worst shot. I then do 5 more, again throwing out the worst shot. I compare targets. Looking for 2 things:

1) Tightness of group(s)

2) Where is the group on the target as compared to the other target.

If my two groups are close to each other in placement on the target and close in group size I take center of mass, left/right, high/low from 10 ring and average that. I then make the sight adjustment using 1/2 of the estimated adjustment needed.

I now repeat the process using only 3 rds and continue till I walk into the 10 ring...

About the same, but I use a spotting scope for each round, and start off with three round groups. Once I am close, I use five round groups. When I am dialed in, I shoot the group with out spotting then check the results after the last round.

LOL, I do the best I can...no spotting scope.

Only thing a spotting scope saves is a few rounds of ammo. I use the one I inherited from my Dad. It dates back to the early 70's. It is a good one.

Spotting scopes are great. They save a lot of walking back and forth and save time and there no squinting to try and figure out holes at longer ranges.

Since I try to go at "off" times and quite often have the place all to myself, I'll set up multiple targets all over the place from 100 out to 200 and then just start shooting and spotting.

There are also steel spinners out there and stuff too but you don't really need to see the bullet mark as long as the little 2, 3 or 4 inch disk is flipping around... :)

I won't bother making the walk down till I'm done and often shoot 100 to 160 rounds into as many as 20 targets of different types.

I also go the group route but I just figured that was because that's how pretty much all of us military types were taught from day one... :)

My 25X rifle scope was clearer than my 60x spotting scope.

I mount the scope to the rifle, shotgun the rifle mounted in bags and pull the bolt group. I sight the target down the bore than sight the target with the scope and go back and forth tell I feel I'm close.

I fire 1 round and see I hit paper then fire 2 more.

Adjust from there to the x and repeat tell I have 3 where I want them.

(I skip 5s and 10s if I've proven this load in this rifle and am just changing optics)

Fire 5 to confirm.

Fire 10 for a benchmark.

Shoot variation of the "box" to confirm scope tracks properly.
