I’m interested in getting a true BC for 12ga slug with rifled barrel to get a Custom Dial made from Leupold. I thought it would be a neat trick in the field dialing the range. Any advice getting a true BC on a slug gun? for a po ole KY boy???? Super Nova, Crio barrel, and have 6 different slugs to try to see what the gun likes. May have to figure out my own BC because may not be on the box. So… true BC at shorter ranges.
A lot of good information in this! I have been messing with this app for awhile but never really understood a bunch of the inputs. Thank you for this run down on it!! ❤
So sight height - half the diameter of your rear reticle + half diameter of rear space where bolt goes, plus total between top of that and bottom of rear reticle
No…. Simple measure…. Center of the bore… to center of the scope reticle…. Which is where the center of the windage cap is. Some people put a cleaning rod down the barrel and measure center of the windage dial, or center of the scope main tube, to center of the cleaning rod in the chamber window where the shells eject on bolt action guns. If you have a super large caliber…. Like a .45 or 50…. Put a brush that is for the size of your bore on the cleaning rod to center it I. The bore and prop it up to center bore on the rear and then measure center cleaning rod to center windage knob. It’s one simple measurement. The distance your sight reticle center is above the center of the rifle barrel bore. Middle of the scope cross hairs… to basically center primer of loaded bullet. If that makes more sense.
I see what you trying to say there… but you might screw that up trying to do it that way. And not all bolts are round. Bell on a scope has a thickness. Etc etc…. Simple is better
That common crack at the bottom of the bolt cover isn’t actually a crack. It’s a seam where the sheet metal part’s corners meet, they welded this together but sometimes it is left slightly open, making it look like a crack. Now if there’s a hairline between the two top holes (anywhere other than the bottom) then that’s a crack.
Exactly. He’s spouting bs in this video. My two g43s have that seam on the bottom and it’s not a safety issue at all. It’s very common to have that seam.
Thank you it was very helpful... im glad you made the video... my gewehr 43 was a bring back from the battle of the bulge i purchased it off the vet who brought it back... let us all remember the storys that are passed on from the vets who brought them back and with them bringing back momentos helping the story survive , thanks Sgt Cole
i retract this is a stupid video you have no idea what your talking about with this app also your explanation of what these fields mean or represent are way off.
FYI Everyone... It's April 2022 and the ios AB Mobile app ver 2.4.20 is rife with catastrophic problems... the solver produces completely erroneous solutions if you input a negative density altitude. I emailed AB and they confirmed they know about it... it's been over 2months now and they still havent fixed it. No idea how many more months it will take for them to fix 2.4.20 with an update... so theres that to consider. Also the data backup feature is completely glitched and doesnt work. So... beware if you are at low altitude or low temperatures ios AB Mobile 2.4.20 will completely pooch your fire solution. They really need to fix this!
I can't find a similiar looking app for Android. The Applied Ballistic app that's available in the PlayStore looks rubbish compared to what's shown here
Thank you for letting us know Larry. FYI, you can slow videos under settings if you ever wish to control their time. But we certainly will take your thoughts into considerations for the future.
Here are some numbers from one of my 6.5s on Applied Ballistics: Correct site height of 2.5: 700 yards, 0 degree shot angle: drop is 16.5 MOA 700 yards, 30 degree shot angle: drop is 13.8 MOA Default site height of 1.5: 700 yards, 0 degree shot angle is 17.4 MOA 700 yards, 30 degree shot angle is 14.6 MOA. So by not inputting correct SH, data corrections are off .75 MOA on level or 1 MOA on angled shots. My interpretation is that Clay's intention was to convey that sight height is important. Not necessarily more important on angle shots.
I can't show the math here, but the concept of it isn't too difficult. If you could somehow have your scope look directly down the bore of the barrel, the bullet would impact low depending on the distance. As soon as the projectile leaves the barrel gravity works and it begins to fall. Shoot a gun flat, and drop a book from the same height; The bullet and book hit the ground at the same time. However, with scopes being above the axis of the barrel, the projectile will cross the plane of the scope twice; once on the way up and once on the way down. This is why the popular 50/200 zero is possible. Generally, the lower the scope height the longer the Maximum Point Blank Range if all else is equal.
Excellent video. Thanks for taking the time to film and edit it and of course for positing it for our benefit. Keep up the good work! (Can you update it for the latest version?)-Migs
