That set of Hornady gauges is priceless in terms of reloading very accurate ammo, and duplicating that super accurate ammo time after time, and after changing settings on your dies.
Measuring off the tip of the bullet to set OAL does not give you the level of precision that many look for when trying to achieve their best effort in reloading to reach the very best accuracy that they can get out of a particular rifle.
Now, if you have a simple set of wind flags to go along with the ogvive gauges, you are going to strike gold in achieving your goals in finding SUPER accurate loads.
Using a simple wind flag used in conjunction with dies that have very low run out on your loaded rounds, is a major step in achieving some really super ammo because you can determine that a simple switch in the wind caused the flyer, not the gun or you.
This thread really took a turn from talking about shoulder bumping, to help save case life and achieve more accurate ammo. For those that are interested in shoulder bumper dies, Standard Forester Neck sizers bump shoulders, Neil Jones makes some incredible Shoulder bumper neck dies with bushings that have the shoulder angle cut in them, and C & H dies also make incredible shoulder bumper neck sizer bushings for their dies. You don't often hear much on the C & H, but they are absolutely top drawer products. Shoulder bumping will eliminate 60% or more of the full length sizing that is needed, not having to lube and de-lube the full length sized cases is what got me on board that idea. Also, Forrester offers a custom service where they will open up the neck on a die to give .002 sizing only on the die, and then the expander ball just barely touching the inside of the neck. Ammo loaded in this way is some of the best there is with often less than 0.001 run out.
