9mm plunk test eye opener

[Racer X]

Wife and I shoot many rounds in competition all from range brass. Everything gets roll sized prior to reloading. All those problems disappeared. Unless it's your own pickups one never knows. 40 is also notorious for issues.

what is roll sized?

A machine/device that rolls each empty case back to saami specs assuring there are no bulges etc. As I mentioned I buy quite a bit of range 9 and 40. Had many issues with jams always in competition of course lol. This was our answer.

I load on a Forster Co-Ax press. I've always been afraid of damaging the carbide sizing ring in my sizer die. Found out I quit having plunk test failures when the die touches the jaws.

For those who shot/shoot action games (NRA Action, IPSC, etc.) you usually go through a LOT of rounds. 99% of the guys I know aren't sponsored or independently wealthy, so reloading is the way it's done (especially on progressive presses).

I started back in the late '70's when most cops still carried revolvers and a lot of the older guys shied away from "jam-a-matics". More than one often asked to see my pistols as I never had jams during a match and they were convinced it was some magic with the guns (mostly 1911's).

Truth was, even though I made my guns as reliable by fit, polishing, and tested magazines as possible, I always made it a practice the night before a match to field strip the piece and chamber drop EVERY round of ammunition I was taking to the match - [the plunk test].

If a lead shaving on a case mouth or some inadvertent deformation of a case would have caused any feeding /chambering problems it showed up there instead of on the firing line. It always amused me how many guys cranked out a couple of hundred rounds the night before a contest, never checked them that way, and then melted down when they had a malfunction under competitive pressure. They usually blamed the gun and used that as an excuse to go in search of another.

I've seen (rarely) factory rounds straight out of the box not want to chamber properly. So I chamber drop/plunk all my carry/SD ammo for the same reasons . . . . .

I resemble that remark!

The correct quote is "Plunk your magic twanger Froggy." It was spoken by the immortal Andy Devine. Of course IMHO, they misspelled his name.

I agree! And I assume you lived in the New York metro area so you could watch it.

I'm plunking everything now like you.
