How would i measure the bore on my x-150? im thinking about having BS make some bullets for me to try out in it but the QLA has me thrown off on how to measure. I havea few GP bullets few and was thinking about pulling my breech plug, push the bullet down the bore and then push it back out the way it went in and measure off that. Would that be ok? Im having a big problem with the 2 stores not restocking the Great plains bullets fast enough for me and would like to give BS a try and then order in bulk.
