	Not sure you proved or disproved anything by driving a lead ball halfway down the bore from each end? In order to really see if there's any choke to the bore I would drive the lead ball only into the bore about 1" on each end, and then compare the two with a micrometer. By driving them halfway, you simply read half the barrel length, not the difference between each end.

I said, "...I then drove a lubed bullet about ½ way down the bore from the breech & then back out of the breech followed by driving another bullet all the way through & out the muzzle." Wayne

Wayne No, I understood, but driving the bullet or slug halfway in from the breech gave you the size at halfway, not the size at the breech end. If there's any difference end to end one would need to simply stop at each end and drive the slugs back out to measure and compare. Driving halfway, or all the way will result in giving the smallest reading where the bore is the smallest for a full length slugging, or smallest for breech to halfway. No way of telling what place within that distance was a smaller diameter.

I agree that my method does not identify the possible location of the smallest diameter but it does indicate that it's not at the muzzle if there is one, which was my main concern since I planned to cut 4" off the muzzle.

	I have always felt most people would benefit from a shorter stock for offhand. This allows the CG to be over your spine more and reduces the reaching many have that causes muscle stress. My guns I am around 12.5 to 13”. That included my Anschutz small bore gun. Just had to set scope to accommodate position changes like prone. This also aided in loading. JMO
