Interesting. As noted I don't shoot heavy max. loads but more of the 90% of max range. I have a few 20 round plastic boxes so I just keep the brass/ammo in the box and reload in sets of 20. Works pretty good and is easy enough to keep track of number of reloads etc. I guess I'll run them to 15 reloads and see how they look. May even go to 20. Thanks.
