Po' Man's Chamber Gauge

[charlie cleveland]

i just drop a nichol down thebreech end and take atape measure and stick it down the breech end till it touches the nichol and this gives me the chamber lentgh ...the nichol trick only works on 8 gauges...i do like the taped together method...the first chamber ga i ever used was a trick that bill murphy posted take a index card and cut it down to where it just will pass into the chamber lightly push it down till it stops mark the card and measure....charlie
