I recently purchased a CZ 527 Varmint in 204 Ruger and topped it with a Mueller Eraticator. What would be the proper distance to zero at? I'll be shooting mostly 40gr factory loads and some 32gr. 200yds? 250yds? Something else?

Of course it's a personal choice. Mine are sighted at 200.

Using the 39gr Sierras @ 3930fps and zeroed at 250yds, I aim for the feet on the close dogs and for the eyes out to about 350 biggrin.gif

  • Interests:First and foremost a shooter.........I have always hunted and for the most part done pretty well. Definitely a better shooter. I hunt big game all over the state of CO including antelope, deer and elk. I between BG hunts I fill in with lots of prairie dogs and this year 2004 I am going to KS for a deer hunt. Just got hooked up for my first official coyote hunt end of Feb. 2004. I have access to lots of excellent prairie property and the hospitality is excellent too. Go figure my big sis married a guy that farms 12000 acres.

With Mil dot scopes I usually sight in 'dead on' at 100 yds. and use the mil dots accordingly from there........that is....by the way.....why they are on there.

copied from another site...

The latest Reloading Guide by Australia's premier reloading guru has just been released; Nick Harvey. He has been reloading for 50 years and been writing about it for almost as many. Many of your (U.S.) top hunters and hunting writers have hunted and spent some time with Nick Harvey. In his latest reloading guide, as usual he lists the Maximum Point Blank range for all popular varminting cartridges. What is Max. Point Blank Range? It is a distance from the muzzle where your bullet doesn't rise nor fall more than 2 inches, meaning an animal with a "vital area" of 4 inches, say a fox, can be hit by putting the crosshairs right on him and shoot, anywhere within the M.P.B.Range. For example: a .22 hornet (45 grain bullet) sighted in at 165 yards has a point blank range of 190 yards. It will be 2 inches high at 102 yards and 2 inches low at 190 yards. He lists all popular cartridges from.17 Rem. through to .270 Win. shooting a 100 grain bullet for varminting work. As a comparison:
.204 Ruger 32 grain = M.P.B.Range 312 yards (sight in at 270 yards)
.204 Ruger 40 grain = M.P.B.Range 311 yards (ditto)
.223 Rem. 40 grain = M.P.B.Range 266 yards
.22/250 40/60 grain = M.P.B.Range 287 yards
.220 Swift 60 grain = M.P.B.Range 289 yards
.223 WSSM 55 grain = M.P.B.Range 305 yards
.243 WSSM 55 grain = M.P.B.Range 301 yards
.257 Wby. Mag. 87 grain = M.P.B.Range 312 yards
These are the most pop. cartridges with the .257 Wby. the only one with a similar P.B.Range, but hardly fun for a days varminting!!

Thanks Red that's exactly what I was looking for.

Now my next question, to get a 270yd zero where is it at 100yds? Is it correct to assume it would be 2" high at 155.5?

You know the ballistic program I normally use still has not included the .20cal bullets. But that seems about right. Glen had some info that included the 20's but I seem to have misplaced it. Maybe he'll post it.

I downloaded Remington Shoot and it calculated 1.64" at 100 yds for a 270 zero with 40gr factory load. That will be me close enough I think.
