Questions for the shooters?

When using a chronograph, how far from the muzzle should it be?

When shooting competition distance, where does the measurement start, ie end of the muzzle, chamber?

Groups.  1 inch at 100, 2 at 200 etc to 10 at 1000?

For the reloaders.

How do you know when brass is used up and should be thrown?

With the chronograph, the muzzle should probably be about 15 feet away.  The blast of the rifle can give you a false reading.  Also if it is sunny with no cloud cover make sure to use the shades, but if it is cloudy you should be ok without.  Also make sure you have good batteries, and it is a good idea to disconnect them when not in use so they do not get drained by accident.  If you are getting false reading another trick you can do is put a piece of cardboard up in front of the chrono to reduce muzzle blast and shoot through it.  Make sure to put an aiming point on the cardboard so you do not shoot the machine.  Remember your scope is higher than your barrel so make sure you are aiming at least 1"-3" high and turn your scope down to the lowest magnification.

Hope this helps.

Ditto on BJ's explanation on the chrono question.

Not sure what you are asking here.

For the most part I shoot almost all of my brass until I either loose it, crack a neck or it won't hold a primer anymore.  Brass life depends greatly on caliber and load shot out of said caliber.  The Laupa stuff I shoot out of greeny for f-class I tend to swap out more often but I have some stuff with 8 firings on it that still holds it's own.

Ok you are at a competition. You are shooting at 500 yds. Where do you place the rifle in reference to the 0 yard line. Muzzle lined up at zero or chamber?



The Groups question is what is acceptable groups at givern yards. IE 1 inch at 100, 2 inches at 200 3 inches at 300 and so on. I know the tighter the better but what is acceptable.

The distance is to the target is measured from the firing line, which is usually the front of the bench that is being shot from. If the line is other than that, it should be drawn on the bench. Targets should be at least, but not less than 100, 200, and preferably 300 yds or meters.

You start shooting bench at 2 tenths of an inch (.2) or so at 100yds, you're doing pretty darn good.

I'm going to stop this procrastinating, just you wait and see!

For group size it depends on the application. Shooting 1 MOA would be fine for most hunting applications. You would want maybe .25-.50 MOA if shooting F class or similar long range target shooting. A true .25 MOA gun is fairly rare unless your willing to shell out $$$.

The difference between the muzzle and the chamber isn't going to mean a thing as far as speed differences are concerned if that's what you're getting at. 

A true 1 MOA rifle/shooter combination in ALL conditions is something to behold under field conditions.  If you can hold 1 MOA to whatever distance you are shooting in whatever position you shoot from you're doing good.  I'd MUCH rather be able to shoot a consistant 1 MOA from 0-1000 on bipods than 0.5 MOA off a fancy front rest......but that's just me.
