[QUOTE="Bart B, post: 1154739, member: 5302"] Sierra's test barrels shoot a 10-shot group in about 1.5 minutes once every 10 to 15 minutes. They grab 10 bullets as they come out of the pointing die machine then seat them in charged cases. Finished bullets come out of that last manufacturing stage at about 80 per minute for the entire production run. .308 Win barrels testing 150 to 180 grain bullets last about 3000 rounds. The cost of those match grade test barrels is part of their wholesale prices. [/QUOTE]
