Years ago I was reading about ACU’RZR TOOL for 22 LR created by Paco Kelly:
See https://leverguns.com/store/acurizer.htm .
Did anybody try this tool?
Although, noted tool was designed to make from round nose 22 LR some sort of HP, I was more interesting in getting better accuracy while shooting S&W M617, six round cylinder. At the first moment I thought that, regarding accuracy, this tool is the solution for a problem that didn't exist. However, when I checked bullets' dias, I found regularly on same bullet variation .002"-.003",.on some as much as .004". To make it clear, I am not talking about Eley Tenex or other high end ammo, just regular one 99% of us are using.
During discussion with a gentleman who has custom built single shot Martini-Henry, I decided to make a better tool, from tool steel, and adjustable travel so bullets' calibration will be uniform, regardless of how hard pin was hit with a hammer. Anyhow, here is my tool:
Once round is compressed, punch is pulled out, that little spacer removed, and punch inserted to drive round out.
We did some testing using that rifle, however, it was done on outdoor range, with some wind. Results were mixed; with some ammo no difference, with another 10-20% smaller group. Soon after I sold my S&W M617, without even testing ammo using calibrating fixture. I've purchased Bisley 357 Magnum, and later Bisley 41 Magnum, and they were much more interesting toppling half scale silhouettes, than punching 22 holes in a paper.
Than, my friend, who is a big time in 22 LR (on about half of local competitions he had taken 1st place), learned recently about this tool, and we hope to test it again, to see would it make any significant difference. I don't expect spectacular result, but testing will show is calibration worth the effort.
