Sighting in .303 British

Don't go to youtube to find out how to sight in your 303 British.
Don't bother trying to find some version of a ballistic calulator.
Disregard much of the information you get here on CGN about ballistic charts and calculators.

Just do as hunters have been doing for a hundred years, sight your rifle so it hits 2 to 3 inches high at 100 yards.
To save ammunition, check the sights first at 25 yards. With your scope sighted 303, you will find that sighted dead on at 25 yards will be very close to what you want, a bit high at 100 yards.
First, get it hitting dead on at 25, then check it at 100.

This should be carved in stone. It works for just about any centerfire rifle bullet from 100 - 200 grains with iron sights. I sight all my milsurp rifles in this manner; start with a big peice of paper at 25 yards, go 2-3 inches high at 100. If you're making homeload ammo, measure your groups at 50 yards.
 
I followed the 25/100/200 yd. advice this weekend to check out an old .303 Lee Enfield and guess what???? Just as expected...She is dead on. The Nazis didn't stand a chance. This is the way I'll be doing it from now on...Does this work for all calibers and guns? eg. small bore (22 cal.), big bore (30 cal.) and handguns? By the way...we got an election going on in Newfoundland. Lots of campaign posters..when it's over, all the targets you want free for the taking...
 
It works for most .30 cal rifles. .303, 7.62x54R, .308, .30-06. It will even be close enough to work for .300 WinMag (it'll be 1.25 - 1.5" high at 200yds and zero at about 215 with 180gn bullets)
