I am thinking I want to typeset, print and spiral bind a field useful data book for my varmint rifle. What I mean is, all my round count and cold bore deviation and range quirks I will leave at home when I am really hunting. My field book will only have distilled useful data.
I CANNOT keep lots of math in my head, I just cannot do it and I have tried all my life. And I certainly can't crunch numbers when under pressure.
So...
I am thinking about having a notebook with come up, wind-drift and correction data for 20 yard increments out to 800 yards.
So if I range a ground hog at 755 yards I round up to 760, flip to the appropriate page and without thinking or memory it is all there.
If I need to correct a foot or three right I will have a moa and mil table all worked out so I can hold over or dial without thinking.
Range cards I have seen just don't tickle my fancy.
What are you fellows doing? I know I know.... you shoot all the time and memorized it all... I just don't get the chance to shoot enough and my memory gets rebooted at work everyday because my job involves a lot of numbers and data! LOL
In any case any suggestions welcome.

DF,
I make my own dope books on Rite in the Rain paper. I took the features from a couple sources and made my own sheets. Copy as many as you need, punch em and put em in a binder, much cheaper than what you can buy and tailored to your needs. Thats where I keep up with all my data.
On the rifle, I have a dope sheet taped to the stock. I normally print from 100-1k in 25 yd. increments with 10mph wind in moa and mils. A good quick back up I also use is to put another in my scope cap. It only shows 100yd increments from 100-1k. I would not have my data only in a book, it needs to be on your rifle or better yet in your head. I know all my 308 data out to 1k in my head, for each 100 yds.

10mph wind... This seems to be the way everyone does it??? 17mph wind multiply by 1.7? I suppose some minor math can be done in the head quick, its just that I am so bad with quick math in the head under pressure. I was having another thought last night. Do you or anyone you know account for: Coriolis Effect? http://www.chuckhawks.com/nightforce_ballistic_program.htmI don't want to venture forth in the field depending on computers but I think those that laugh off coriolis may have a point but on the other hand may also be ignoring physics.

Thanks for the reply Jim! I thought maybe this one had died a slow death of no-replies! LOL

Im my experience, shooting out to 1k yards does not require an adjustment for coriolis. In a no wind condition I can hit point of aim at 1k. We have just begun shooting out to 1 mile and I understand it must be accounted for at that distance, we shall see.

JimD, I always use a waterproof pen to write on waterproof paper like Write-in-the-Rain. I also use some synthetic papers.
When you say you print on the WITR paper, are you using a laser printer or inkjet printer? Is it waterproof on that paper?

Lee24,
I meant I use a copier, but you can use a laser printer. Inkjet will run.

That has been my experience with inkjet printers. I have a set of pages for all kinds of shooting data for my rifles that fits in a common mini three-ring binder.

Plastic laminate the pages when complete.

Too thick. Use the vinyl or waterproof papers and a waterproof pen.
