Awhile back I ordered 500 pieces of 44mag brass. Upon it arriving I opened the box and started inspecting the brass. picked 20 random pieces of brass out and started taking a hard look at them.

Cheap electronic scale: brass +/- 1gr
flash holes uniform & round
primer pockets tight (10 federal went in with hand took/10 cci mag used press)
trim length +/- 1/1000th's

The only thing I saw was a little chatter in the inside of the rim of the case with a 5x loop. The lyman m-die expander took them out but I decided to use a chamfer tool and took did a quick pass with it inside and outside.

2 years ago I bought 2000 pieces of 357mad brass from starline. Had the same results as above.

If I have to buy brass for the revolvers I look no further then starline.
