Re: Air Temperature Effects On Muzzle Velocity By Gustavo F. Ruiz
I'm new to this forum and can easily appreciate the several points being made here. If we all are about long range hunting, then we must strive to be as "ethical" as possible with regards to first round deadly hits and not wounds. What I've learned over the years hunting in TX on hunting leases with many different lease partners is that what one considers long is short for another and vice versa. We should all strive to both stay within our own ability for the shot on game animals as well as strive to extend our ability through as much pre season practice as possible and the pursuit of the best tools we can build or buy. We build the finest rifles we can, we buy the finest optics for our rifles and for determining range, we spend hours/days /weeks perfecting our reloading procedures and tuning our ammo to the gun, we compete at long range as often as possible, we use spotters and target pullers/pasters to give us immediate feedback so we can assimilate as much shooting knowledge as rapidly as possible and in my opinion, we need the best ballistics software predictions we can get because as many have pointed out, when it's oh-dark-thirty and we are by ourselves on a hillside or in a blind we need to know with as much certainty as possible what will work with the highest odds possible for the first and most likely the only shot at Muy Grande. The more intelligently I can model my equipment's performance under widely varying conditions = the better. I regularly set up at 650 yds on whitetail doe across a valley from hillside to hillside on a easterly heading. In central TX it can be mid 20s F in the morning and mid 60s F the same afternoon. And my dope is always enough different that without practice and predictability it would be an impossible shot. Up to now, I've kept pretty decent data for this shot as well as many others in competition and I've yet to have the ballistic calculators agree with reality past 400 - 500 yds. So I'm always looking for software that assimilates more and more variables. I bought Loadbase last week and immediately started testing it against as much historical data as possible and I have to say that so far it is showing substantially greater correlation to reality out to 1000 yds than any of the other half dozen or so programs I've tried. If logging MV vs Temp will give me additional insight, then i'm all for it because I know with certainty that rifle and ammo at 28degrees perform differently than at 90 degrees.
Best wishes to all
