As many of you may know by now, I am new to firearms and hunting.
In fact this season will be the first time every for me to go hunting. (55 yrs old)
I just purchased a Weatherby Vanguard 2
.270 caliber Rifle and bought a Vortex Diamondback 3-9x40 scope
On the VORTEX OPTICS
website they include a Long Range Ballistic Calculator
I really don't understand this information much as I've just begun to use it.
Lucky for me, besides allowing you to input your own data for those who reload their ammunition, they also include a drop-down box for standard ammunition which then populates the information accordingly.
I have been trying it out just to see what information it provides and I noticed something perhaps one of you could explain.
I first input the weather conditions for Today (July 10, 2013) which is 100 degrees, no wind, no moisture.
It indicated that the bullet drop would be 5.5" at 400 yards
I then input weather information showing the temperature at 35 degrees, a 10 mile an hour wind from left to right and 50% humidity. That change re-calibrated the bullet drop to 5.7" at 400 yards
I'm assuming that isn't all that great of a drop between 100 yds. and 400 yds. but, I was wondering if it is the temperature which made this drop occur?
I also found this website for Weather History
which allows you to go back in time to say, last years opening day to see what the Temp. and Winds and Humidity were like on average.
I thought it might be a good tool to see what I might expect on average for this years upcoming season.
Anyways, does the colder temperatures account for a larger Bullet Drop
Being new to hunting and Firearms, I am practicing at 100 yds. and 200 yds. range and can't see myself shooting any further than 400 yds. what with my skill set being new.
The VORTEX Diamondback Riflescopes I purchased comes with a Dead-Hold BDC reticle
BTW, the reason I decided on the Vortex was due to their outstanding Warranty
Unlimited Lifetime Warranty
No warranty card to fill out
No receipt needed to hang on to
