Re: slings, effective?, legal?
Next time you're in Louisiana, come shoot with us. We have smallbore silhouette matches on the third Saturday of the month in Mississippi just past the Louisiana/Mississippi state line on near Slidell. On the fourth Saturday we shoot in Gonzales which is between Baton Rouge and NOLA.

That 2/3/2 log is my method. It means two vertical graduations on the barrel then 3 large on the knobs top and two clicks past the 3 mark. Log suits the way Leupold scope adjustments are marked and what can be run off on my label maker to stick on the scopes body, Ammo box lid etc. Everybody's method of logging is different, no matter long as you use the same method every time and understand it.
On offhand zeros. I shoot a group on spray painted paper targets. Long run 10 or 20 shots. Back at the bench I give the target which resembles a shot gun pattern a critical look. Ignoring "off" shots any outside the "normal" group, use a framing square to box in the majority. Then run a X through the corners of the lines. Center of X is center of impact. Make my scope adjustments from off center, and check it again.
If you were shooting bench rest ignoring off shots is a no no, however if finding true offhand zero don't want to factor in obvious jerked triggers or other errors. Objective is to find the correct scope setting that centers up bullets impact. Centered groups make for more hits on steel targets. 80 or 90 % of shots center is true center. You will find same time the rifle centers different depending on how it's held. Offhand zero is not bench zero. Close not the same.
Other thing if finding true zero offhand you will see the winds effect, most of the boxed in groups will be rectangular. Other day my Ram long run paper group 40 shots was 3 1/2 minutes high by 4 1/2 minutes wide with a few flyers outside the box. 3 1/2 minutes is 1 inch too big to hit every ram it's about 2 1/2 inches high body. However if sights are set for center misses will be 1/2 minutes too high 1/2 too low. With most of the shots on the critter. One or two minutes off from true center will mean more misses. Actual match it's not quite that precise, however hope you see the point centered = more hits.
Last on distances and ranges. Few Silhouette ranges are measured precise. I am MD for HP and SB our club, other day one of our shooters measured the berms with a range finder, and found they were off the match flyer distance. Not a lot but off. No matter long as your notebook tells you were my rifle impacts that range on that day. Temp, wind, change in ammo all will throw your point of impact off. And no telling if his range finder is reading correct. Good notebook with lots of data backed up by the sight in period is what counts score wise.
