Jul 31, 2011 · OAL is usually listed as the recommended length to fit in all firearms of that chambering. A load with a short jump to the lands will usually result in a longer than SAAMI spec (manual listing) oal. Most factory rifles seem to like the jump to the lands at about 0.020 - 0.050", in my personal experience.

Feb 10, 2023 · I’m putting parts together for a build that originally was gonna be a mid weight 300 WM but I’m starting to think maybe I’ll go PRC. Anyway I’d like to know what overall length you guy’s are typically running with the long high bc bullets such as Berger 230’s, 245’s or the Badlands Super...

Dec 27, 2012 · OAL causes lots of confusion new guys and quite a few old hands....that should not be. And there is NO way to "calculate OAL", chambers vary too much for that. There are three ways we can establish an OAL for rifles. First is the max length that will feed and function through the magazine OR go by factory length - that's the SAAMI standard length.

Feb 21, 2020 · You now are the proud owner a a custom fire formed case which will be exclusive to only one and one weapons chamber tapped to a 5/16" X 36 TPI that will fit on a Stoney Point or Horandy OAL Gage. Click to expand...

Sep 12, 2012 · I have tried the Frankford arsenal gauge and I dare you to try and get the same measurment twice (even close). I have also tried the Hornady OAL gauge but the brass was not sized and wouldn't fit in the chamber ( brass far to big) and when my father-in-law tried to size it, it crushed the case...

Jan 16, 2018 · Looking to troubleshoot what I suspect is a VERY short throat, and would like to know the OAL and/or base to ogive for factory ammunition with a 175 ELDX and 180 ELDM for a 7PRC. Hoping there's some folks on here who have a box and a …

Jul 23, 2008 · I'd appreciate a bit of help regarding the OAL of .270 Win factory ammunition. SAAMI spec is 3.340" max & I want to know how various factory rounds compare with that. Make, bullet weight, bullet type & OAL would be appreciated. If anyone has a Hornady OAL gauge, I'd appreciate the measurements as both OAL & using the gauge with appropriate ...

Feb 18, 2011 · So I took my Hornady OAL gauge with modified case and a Nosler 250 AB. So when I measure the OAL (end to end) I get an average of 3.872" and 3.215" to the ogive. When I use the method of putting a bullet in the neck and close the bolt I get a OAL of 3.878". So if I want the bullet 0.010" off the lands I the bullet will still be 3.862" OAL.

Jan 16, 2018 · Thinking of a rebarrel, and wanted to get a rough idea of OAL, as my magazine is rather short for a long action. I plan to do this math for a few prospective bullets, and determine if my magazine box will accommodate all of them before deciding to proceed in the build. Went to the SAAMI drawing for 264 mag (here, page 82). I believe the bolt ...
