I have no way to test pressure but I have a .30-06 barrel on its way, a donor action found (I think), .30 Gibbs dies, a stock and a nice trigger. The plan is to test a 22” Factory barrel first as a .30-06 with several bullets in the 150-200 grain class and then punch it out to .30 Gibbs and re-shoot the same bullets. Will basically be looking for classic pressure signs, backing off and looking for accuracy. If the Gibbs can offer similar accuracy at .300 WSM velocities then I have gained something. If the accuracy node is down in .30-06 territory then the Gibbs is essentially a waste other then maybe a little less brass trimming.
