Hello, I recently purchased a Hornady OAL gauge and was trying it out the first time tonight on my S&W 1500 .270. I measured multiple times with the OAL gauge and bullet comparator on the calipers and was getting consistent results (2.929, 2.923 and 2.923) when using Sierra 130gr BT. I came up with an OAL of 3.393 allowing for 0.030 off of the rifling. My question is, does this seem excessive in length? The Sierra manual lists an OAL of 3.300". Curious how much OAL can vary from what is listed in the manuals when using a OAL gauge.
Thanks
Matt
