do you do a test run on powder charge and primer make/type before loading 1,000 rounds.
I do a run of 10 or 15 test, shoot them and do corrections accordingly or just go with the configuration. I look up the data for the powder mfg. on the net and go from their loading chart but I also have two new books I do like to test a few before loading a bunch. the only drawback is time and a close place to shoot the test run.

I know what all the loads are that I shoot. So for the most part no I make runs of atleast 5K. I might make a run of 5K in .223 say 55 grn FMJBT Hornady bullets then change over to .45 and run about 4 to 5 K of say 200 grn Plated round nose bullets. That's what I did with only one S1050. It worked out good as the machine must be taken down and cleaned at 10K anyway. Now I have the option to keep processing .223 brass while I load .223 or .45. Also I now can have the machine with the feeder running .45 and be loading .223 on the other. With the bullet feeder on the .45 machine it will run all by it self. All I have to do is stop it about every 90 rnds and add primers , bullets and brass. Every 700 rnds or so it will need powder too. Loading the .223 I have to add powder every time I refill the primer magazine . Because I'm stopped anyway I throw in a hand full of brass too. I don't use the bullet feeder for the .223. To do so I would have to remove the powder CK die and I don't want to do that. Besides I use a Cal Die to seat my .223 bullets and its just as fast as the Mr Bullet feeder, the press never stops for that. The 1st thing that will stop me is the primers and for that I use a RF100 set up for small and large primers. OH yes I do drink the blue koolaid. If for some reason I do need to work up a new load then YES I run about 20 or so and test them for the desired results |
