[QUOTE="Petersen, post: 769346, member: 8372"] Looks like I was wrong. Shot mine the past two days and it is going faster than it was last fall. So, A combination of the barrel getting broken in, took a little more off the neck thickness and one more grain of powder (75.5 gr. h1000). The chrono read an average of 3150 yesterday and 3250 today. The chrono is not the best so there is some error sometimes. But I can confirm it is about an inch high at 100 and dead on at 200. So it is somewhere in the 3150-3200 range. I will confirm velocity at further ranges when I get a chance. [/QUOTE]
