I just got thru casting some more 30-06 bullets. I weighed and separated them into 3 groups by weight. They are 170 grains, 171 grains and 173 grains.
I load with Winchester cases and primers and the powder load is same. Sighting in with the 171grain bullet, I get a group approx.: 2 inches in diam at 100 yds. What can I expect if I load the lighter and heavier bullets with same cases and powder? Drop or rise of bullet ? Group sizes getting larger or smaller?
Just thought I would throw this out here, before loading up the lighter and heavier bullets. Heading to the range with the rifle later.
