Re: A ny Advice Before I Shoot At My Chrono?
Invest in a cheap laser bore sighter. I bought one for about $20 at a sporting goods "big box" store.
Insert it in the end of the barrel, turn it on, sandbag your rifle on the bench so you have the scope or sights centered on your target.
While setting up your chronograph, just use a hand as a laser target to see where the bullet will pass over the chronograph. Better than relying on friends or relatives to say "that's great, you won't hit it".
Also, the laser helps you make sure that the bullet will pass over the "sweet spot" of both sensors so you can get readings from the very first shot. Nobody likes repeated "Cease Fires" so someone can run out and adjust their chronograph because they keep getting "no starting shot detected" or just plain "error" messages.
Also, invest in the sturdiest tripod you can or choose to afford. One of those "daddy long-legs" tripods that's designed for a candy bar sized digital camera doesn't cut it when it's got a pound or so of chronograph mounted on it and gets hit with the muzzle blast of any sizable rifle. If you insist on cheap then at least fill an old milk jug with water, put it under the tripod, and then tie it down to the jug with a bungee cord. Not only will it keep your tripod where you set it up, your readings will be more uniform.
