I have some 200 grain sample bullets to test. My first test is to see how consistent is the weight from one bullet to the next. I’ve previously learned this is a critical factor for accuracy – to have all bullets weigh almost the same. (I’d like to see +/- 0.5 grains but know other shooters who demand +/- 0.1 grains.)

Speculation is a double-charge when reloading caused it. (Shooter had no serious injuries … except to his wallet.)

Here are some tips and a summary of some key parts of that written process, many of which apply to the Dillon 650, and some tips that may apply to any reloading effort regardless of brand.

In no particular order, here they are.

One pass, fourteen fail and 985 to go.

Any reloaders try these products yet? I’m interested in the stainless steel media. See http://www.stainlesstumblingmedia.com for products - I’m thinking about the 5 lbs of media and, other than washing it occasionally to remove the dust, it should last forever. (But note they say it will not work in vibratory cleaners. You must tumble.)

A little math can get you in the ballpark very quickly.

This is the last of a five part series on tolerances in reloading.

This is the fourth of a five part series on tolerances in ammunition reloading.

This is the third of a five part series.

In this part we look at Cartridge Overall Length (COL) and crimp to discover what tolerance is recommended and whether or not we can get accurate measurements with the available instruments.
