[QUOTE="Schnyd112, post: 1122925, member: 90453"] With smaller diameter barrels heat rises chamber to muzzle pretty well. With thick barrels,open the bolt and let them sit on the bipod. There is less metal to cool above the chamber and they seem to cool faster when laid horizontally. I have a hunting gun that does not like 4-5-6 shot strings but will put 3 in .5 moa all day. My heavy barrel factory rifle will put 5 well within moa and 10 at about .80 moa. Each rifle, each barrel is different. Test it, take copious notes, and shoot as often as you can. Get comfortable with everything so if stuff goes downhill you know you can shoot each rifle with confidence. Also remember that rapid heat change fatigues metal more than a natural heating-cooling period. I know lots try to speed up the cooling but material science tells you natural heat exchange is best. Give them time. Shoot other guns. [/QUOTE]
