just posted this on another thread, thought it might be appropriate here, FYI..

Competitors say: 1st shot= fireform, 2nd-4th competition, 5+= practice cases.
Personally, I purchased the "AMP" unit. The justification was "consistency". I can feel the tension of every bullet seating, and know they are the same (as close as humanly possible). I anneal as part of my process in every loading.
Now that AMP offers custom programming, all of my cases have specific programs (per lot). Rabbit hole? YES. But it works for me.
That said; I load only Norma and Lapua brass (currently .223Rem, and 6.5CM). I cull any cases that feel different during any part of the process, or show signs of fatigue. I trash them at 20 regardless (last Norma batch I tossed 7 out of 200 during their life for various reasons). My current batch of 200 Lapua is @ 12, and I have tossed 2 cases. Powder charges are somewhere north of max..
I chose to put my money into precision loading, and good factory rifles (Tikka for one). The cost of excellent hand loading equipment ( AMP, FX 120i, custom dies), pays dividends for many years, with average ES in the low teens, and consistent sub MOA accuracy.
Do the math to see what works best for you.
my opinion.. hope it helps
