[QUOTE="DJ Fergus, post: 2423486, member: 93895"] Three shots groups is all that I shoot. Now I will do multiple 3 shot groups during load development but it's going to be several hours later or the next day. From my standpoint, 5 shot groups will tell you if your barrel is starting to bow as it heats up but doesn't necessarily mean your load work up is bad. When we run very hot burning powders like RL26, N570, and even retumbo which is less as hot burning than those two previous mentioned, you would need a very heavy contour barrel for it not to walk shots when going for 5 shots. Or it would have to be 100% perfectly stress relieved if it's a Sporter contour. Most folks won't run those powders for competitions with long shot strings. 1/2 moa & under is my goal for three shots. It's not always easily achieved but I normally run very hot burning powders and that's a contributor to a barrel heating fast. Sometimes I do much better than 1/2 moa. Most but not all who consistently shoot .1s and .2s are going the extra mile with sorting and maticulously prepping cases and some sort bullets. I do have a a couple that will shoot as said without this prep & sorting but I'm using very consistent bullets and brass along with cooler burning powders in those rifles. [/QUOTE]
