It would help if I rephrased the question this way.
50 bullets we’re cast on Monday, 50 on Wednesday. All with the same methods. They are sized, lubed and checked and kept separate until you shoot a match on Saturday. Four 5 shot groups are shot in the morning. Two with what you cast on Monday and two were shot with what you cast on Wednesday.
The same with the10 shot groups. One was shot with Monday’s casting, the other shot with Wednesday’s castings.
I did a sloppy job of framing this. What I’m driving at is whether the bullet to bore fit, thus accuracy, will change from casting session to casting session or for that matter throughout the casting session for the beginning caster chasing cast accuracy .
Will the 250 pcs Ric cast on October 1st be as accurate as another 250 he will cast two weeks from now. To level the playing field lets standardize things by saying he only uses Linotype from RotoMetal.
Unless your cadence is mentally fixed I wonder if it can be done without the use of timers/temperature probes.
I left myself a big “out” in that last sentence. I believe Ric, John, Larry and a number of others on the forum have the cadence locked down.
But for some of us I think the mold temperature could creep up or down and change the bullet to bore fit enough to cause accuracy degradation/fliers. Thanks for letting me mumble through this. Bill.
