Re: ladder method
Both methods have some merit but are nothing more than a poor man's way to get 50% of the info a good chronograph will tell you.
By learing how to "read" the chronograph, it will teach you just about every aspect of the "why's" and "how's" of what is going on with your rifle. They tell you way more than just the velo of your bullet.
This is why one of the most well respected ballisticians of our time said that of all the advancements in firearms over the past century, none are as helpful to the shooter as the development of portable, inexpensive, and accurate chronographs!
Get one and never look back! Trust me on this one. [img]/ubbthreads/images/graemlins/wink.gif[/img]
If it's not far, it's boring.
