Re: Need help from anyone who has ever blasted their chronograph !!!
First, I don't know how that happens, if you set up correctly?
To do this, first place your target.
Second, get your rest or bags or both in place and set your rifle up with the bolt removed so that you can see the target through the bore.
Third, set your Oehler 35P in place, at least ten feet in front of the muzzle.
#4, 5 6, etc. is to keep moving your tripods, raising your tripods and nudging your tripods so that the bore is looking through the inverted triangle in the upper half. You can't rush this process, make sure it is right.
It really facilitates things if you have one person looking, and another moving the chrono. The one looking through the bore needs to be behind the yellow line, but that is not hard to do.
Lastly, it is not the end of the world if you do, (somehow) manage to hit a sky screen on an Oehler, since the machine is with you on the bench. I think a sky screen costs about fifty bucks, versus total junk with the others that place the whole unit in the line of fire?
Good hunting. LB
PS You think you need advice from somebody that has blasted their chrono?
