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.

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!!

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?
