I have 32,250 of .38 special and 250 of 30-30. The 30-30 is with a Lee Handloader. The .38 special with a Lee Challanger Breechlock kit and rcbs dies. No experimenting with the 30-30, basic factory loads. The 38's have gone everywhere from 110gr to 200gr and have settled on a steady diet of 150gr LSWC Kieth Style over 3.5gr of Universal and that is all I really load any more.
I just started laser bar coading each case and use Jasper's loading computer program with a hand wand bar reader. This is just for knowing how many times each case is loaded and with what. A little time consuming, but for now, very interesting. As you place a case in the shell holder, the reader catches the bar code and adds it into a really nice data base. You add the load recipie prior to start. The reports come out in 15 different reports or charts & graphs. So far I have only been using 250 cases with the system. It also includes target data you have to manually plug in based on an x,y of the special target grid that you print off new. Each case is bar coded as well as sequence numberd. I get my at home daughter to plug in the target data. Then you can print a target with all shots or selected shots over time (even 1 coded case shots over time, you have to manually track for that data by sequence number and target x,y placement, but the sysytem can make the selected reports), you can then see over time how better or worse you are getting for groups and/or actual placement per case. Out of the 250 cases, reused approx 7 times each, I have had an attrition of 250-32 cases, started losing cases for various reasons at 4 re-uses. Really cool to follow, gets old fast though, you have to be dedicated.
