I'm very, very new to reloading. I do not have a chronograph, I could probably use one if I called several people. I've got a hunting load that's working really well for me, and I'm not sure what kind of velocity I'm getting. Was hoping some more experienced people on here might have some better guesses at it than I do. Trying to make a rough ballistics card out to 700 yards.
190 Berger VLD Hunting Bullet
88.0 gr 7828
CCI Magnum Primer
Rifle is Remington 700 APR w/ 26" barrel
Temps average 50 degrees
About ten feet above sea level, on the high ground.
I would just shoot to make your card rather than guess a velocity and hope your getting the BC as advertised. I have never had great luck basing drop strictly off MV and calculated values.
I'd add that when you actually shoot at the extended ranges you will have a MUCH better idea of what the accuracy of your load is at that distance. 1" @ 100 yards does not equate to 7" @ 700 yards. Not anywhere except on the web, that is.
Many shooters are limited to load testing at 100yds - 200 yds and make assumptions as to bullet drop and group size at all other distances. Actually shooting at these distances often tells a whole different story.
