Long range for beginners

Doesn’t seem to do anything any better than a regular bubble. 

I just look at the bubble and center it up

One of the best sources of information I've found.  Read every word and watch every video from Sam....then do it again.  I'm a better reloader, rifleman and hunter because of what I've learned over the years from Sam.

I like Sam too. I’ve watched all his videos

Accuracy and Precision for Long Range Shooting Chapter 8: Leveling Your Sights shows how 3 degrees cant with .243 can induce horizontal error of 16.2" @ 1000yds (0.4" vertical); 41.0" (only -1.1" vertical) @ 1500yds. Human eye only discerns about 3 degrees under best conditions....before introducing optical illusions of tilted visual references, Cant gets misinterpreted as horizontal wind error and one ends up chasing their tail.  Many levels are not much more accurate I’m learning

higher temperatures and pressure will compromise the bubble size causing level inaccuracies. Typically air bubble levels require 3° to 5° to even register movement;

Wow - was hoping I was within a degree with bubble.  I better stick my phone on there and see what its digital scale reads vs bubble.  16” is about right.   Tangent of degree cant times holdover = shift ( maybe times 2?)

I've seen some guys putting in consistent work at 1000 yards with a bubble

I use a level everyday at work. Bubble works fine till it’s cold or hot! I have no troubles with my bubbles till above 85 or below 40.  It’s no different than my work levels. I’m thinking I’ll go with ceramic ball from accuracy first, at least it will be the same size at all temps

I was hoping to get a solid 1” load at 300 yards before moving out to a 1000 yards but Im going to live with 1.5”’and see if it holds up at 1000 yards.  These 300 grainers give a pretty good pop so I  may be only a .5 moa shooter with em anyway.  I had the the ABM app so bought the custom drop info for $2 after seeing jasnts post (thk u) so will see how that compares to the sig rangefinder computer that uses the same author.

You shooting the 300 grain EH or OTM?  Have you tried jamming them?  Mine shoot best between 5 in and 3 off.  OTM would be 15 jam. And yes you can still eject a live round without losing bullet. I run .0025 neck tension.

.338 Edge. 300gr OTM jammed .015 @ 300 yards.

Nice.  Gonna jam some elites 2moro .  Should ladder for powder and seating but gonna just try a couple loads and see if I get lucky.

[jasnt]

Nice shooting BH.  What action you running and what speed is your load?

[Magnum_Willys]

Tested my bubble level with a digital.  1 degree puts bubble well over lines.  I'm pretty sure I'm holding within 1/2 degree of verticle with this standard wheeler bubble level.  That still could move me 4" at 1000 yards.

how did you test it? And at what temp?

I tested mine yesterday with same results.  I would say when I am shooting I am under 1/2 degree from what I showed .   Did it in house at 70 degrees then after that I sat it out in 93 degrees for over 2 hours and it was the same result.

Typically air bubble levels require 3° to 5° to even register movement;

I think that might be more realistically 0.3° to 0.5° to register movement. I can detect smaller movements than that with most of the bubbles in my shop (including some cheap carpenters levels), as well as what's on my rifles.

[Jonathan_S]

If using a bubble to level up the rifle when shooting was insufficient then it would also be insufficient when mounting I suppose.  Which would give us 6-10* tolerance and I'm just not buying that
