[QUOTE="Derek M., post: 433050, member: 2693"] If you really want to be fair to your load testing then each group will travel down the same path. So, to that, you can take your cleaning equipment and clean between every group, take some extra factory ammo or other non testing loads and use them as foulers. This also allows for barrel cooling. I use to do this and found it to work very well but was time consuming. So, you'd start with a clean, dry bore, fire a fouler, then a 4 shot group, then clean, let bbl cool down completely, and start over. I always prop my rifle upright between groups as this seems to assist cooling, letting bore heat dissipate more quickly. Most of the time I don't do the method above anymore simply because I'm lazy, and don't have the time, plus I'm at the mercy of cease fire at the range. I usually load the number of rounds for testing which would include a regular cleaning anyway, which is about 21 to 24 total rounds while doing load development and this system has served me well also. I think the real key is starting with a barrel that has a few rounds through it and is "broken-in" to begin with. Start with a clean bore and shoot 20 or so rounds, even up to 30 before a thorough cleaning again. The key in my opinion is barrel cooling. [/QUOTE]
