Need, no. It depends on what he is comfortable with. Many people will dial in a long shot over 500. This takes a scope that is proven to be repeatable. I have not personally used a BDC reticle for shooting much. I have only played with them a little and wasn't overly impressed. I feel more secure with turning the turets for any shot over 400, but that is just me and I'm no expert!
I used to re-load but now I "hand-load".
-- Well, at least I try --
he needs a load that will shoot a 4 to 5" group at 500 yards. you don't say if it is a remington 700. i would stay with the mid weight bullets from a 95 berger and 88 berger; 87 horn hp or v-max down to 70 baltip. i would try re-19; i4064 ; then i 4350.
if 500 yards is your max, id humbly suggest the 55gr btip, or the 58gr vmax. zippin out at about 4000fps, the 55gr will be better at short to medium ranges. it will also kill alot better. any hit in the body will kill a yote with a 55. the slower tougher bullets will leave you trackin em with a marginal hit (of which you will likely have a bunch of), although, if you are going to try to go much passed 500 or 600, the 55 will leave a pretty sour taste in ur mouth... the 87gr vmax would probably be the best choice for much farther with a factory gun. it will get you out and passed the limits of your gun...
my friend would like to use his 243 for coyotes and would like some advice on how to get out to 500 yards with it. could anyone help him?
Huh? I live where you can see for more than a 100 miles in fairly open country. The yote's I've seen at more than 300yrds were gone in a split second before I could shoot.. I've called them in within 15 yards and most I get under 75yrds. Must be some slow yote's your friend is going for.

My advice to you, shoot a 85-87gr. hp and zero for 200yrds. Anything from 100-300yrds. hold dead on or just a hair under or over. For 400yrd. shots hold just over the back and for 500 where the the thinner crosshair connects with the thicker crosshair place that on his back. That should get you in ball park. A mil-dot scope helps out alot. At 300yrds. u got about 6" of drop with a 200yrd. zero at 400 20", 500 40". 10" is hit or miss judging distance is crutial. If wind is blowing over 5mph u need adjust a couple inches for longer shots.
