I ended up with 4 categories:
From the left:
1 - 51 bullets, between 173.3 and 173.8.
2 - 164 bullets, +/- .2gr of 174.0
3 - 205 bullets, between 174.2 and 174.7
4 - 70 bullets that were over (but not too much) 174.7.
I only totally rejected 10 (will use for seating testing) - the heaviest being 175.6, and the lightest was 172.5.
The diameters were reasonably consistent: between 0.3105 and 0.3115, but some of the canelurres were deeper than others. A lot of them had little 'dings', but that's what happens when you put 500 bullets in a plastic bag and send them by post.
Generally I'm happy with what I got for the money - I have more than 100 'plinking' quality (can use to practice the 'mad minute'), more than 200 for load development and practice, and over 150 I can use for comps.

I'm going to get 100 Sierra Matchkings, to do a comparison with (also, shot groups comparison). I want to see if the lack of a cannelure, and the greater quality make a difference to the accuracy. Midway is sold out...any suggestions?
