[QUOTE="Mikecr, post: 1302268, member: 1521"] It doesn't seem unusual that MV would go up a bit & level off as a barrel heats. I've seen this many times, and my cold bore load development finishes with 2 shots ~30sec apart(from dead cold). Even though follow-up shots are against one of my rules, I still want to know my capability. Not so much mv-wise, but a 10min shot rate and 200yds always seems least accurate for me. So that's where I spend the most efforts. This is not precision(grouping), but accuracy. You would not see a competitor(who's actually competitive) shooting for record precision from a cold bore. Given their way, they would at least shoot during a sighter period to get their barrel up to stable temps. That is where they know exactly what the gun shoots. [/QUOTE]
