[QUOTE="Bigeclipse, post: 1003449, member: 52437"] I had the same question a few weeks ago. The conclusion I was given is let barrel cool about 3 minutes between shots in a group/string (this should be between 3-5 shots). Then let the barrel cool 15 minutes between strings, Same thing if you are doing an OCW/ladder test round robin style with say 5 different powder charges which totals 15 shots (3 shot groups) then I would shoot each shot...3 minutes apart then wait 15 minutes before starting the next string of the round robin. Once you find a load you like...I would confirm it is a good HUNTING load by shooting 2 shots rapid fire. If they group well you are done. This will allow you a first shot, plus a back-up shot if needed. Now if this is a LONG LONG range rifle 500+ yards, you may need several sighting shots...then you will need a rifle that can group 3-5 shots in pretty rapid succession which is why people gravitate towards a varmint/bull barrel set-up.
