2024年12月8日 · Question - does anyone here have the ability to tap/Tread a case for a Hornady OAL guage? I have a fired 7SAUM piece of brass I want tap/thread. Send me a pm and price if you have the ability.

2012年12月28日 · 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.

2008年7月23日 · 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 ...

2008年1月31日 · Last night I was going to load some rounds for my dad's remington 700 270. Using the hornady OAL gauge I came up with 3.53 (bullet on lands). Something can't be right about that. The bullet barely sits in the cartrigde. I checked it a bunch of times and even did the old way of putting the...

2018年1月16日 · What really has me concerned, is that the180 ELDM and 190 A-tip are ~0.20" and ~0.07" shorter to the lands than the 3.32" OAL quoted in the Hornady Manual. This is particularly weird, since my 7mm Mag, as well as the other 7PRC barrel had the ATIP and ELDM at very similar OAL/BTO to the ELDX.

2019年10月15日 · 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 ...

2013年7月7日 · Base to tip OAL will vary with bullet length and shape. Different bullets will contact the rifling at different lengths. A monometal bullet like the Barnes will be longer for a given weight because copper is less dense than lead. Have you tested for seating depth? Barnes recommends seating their bullets .030 to .70 from the rifling.

2009年4月30日 · I consider COAL and OAL the same thing and is defined on the SAAMI Glossary SAAMI | Product Manuals in the 2nd definition "LENGTH, OVERALL 1. Firearm: The dimension measured parallel to the axis of the bore from the muzzle to a line at right angles to the axis and tangent to the rearmost point of the butt-plate or grip. 2.

2003年11月10日 · Back in the old days there weren't any of the wonderfull tools that we have the option of buying today. Yet proper OAL was important even then. So what was done was to take an empty and unprimed case, and seat a bullet long, and then insert it into the gun and close the bolt. That would seat the bullet by jamming it against the lands.

2020年2月21日 · Sounds short. If the rifle has a longish history in service, you might think about securing some nitrile glove fingers over the muzzle and with a thick folded towel for the muzzle to rest on, clamp it to a work bench and fill the bore to chamber with Hoppes Benchrest 9 and let it soak at least over night.
