Combine Neil Jones' & Paco's tool. Here is how:
When time allows I combine:
A. Sorting cheap ammo with the Neil Jones .22 RFG (to eliminate flyers) into separate rim sizes,
with
B. Accurizing the sorted rounds with the Acu'rzer/Nasti-Nose die tool, made by Paco.
The results are surprizing.
Without fliers, the sorted/accurized (cheap) fooder prints never-before-seen tight groups.
I don't bother accurizing the "irregular" (very thick) rimmed rounds, simply because they do not fit flush into the acu'rzer tool for proper modification. This is further proof that the Neil Jones' and Paco's rimfire tools, although diverse in their quest for rimfire accuracy, can be used in conjunction and produce the goods.
Since I started this combined technique, I haven't looked back.
Now all my guns shoot straight, even when I don't!
