This is my first post, but I've been skulking around looking at the topics for a while, and I am a new user of the Point Blank program here. I am an old soldier, and my shooting expertise has been mainly from 300 meters in. Recently, however, I talked my wife into letting me pick up a new long gun. It's a Winchester Model 70 in 300 WSM, improved with a free-floated heavy barrel and laminate stock. I haven't much long range experience - as I mentioned - and I was wondering if some of you more experienced folks might lend a hand.
I am looking to create a fairly reliable ballistics / trajectory chart for my favorite load, the 150 grain Ballistic Sivertip. My gun eats the stuff up and shoots it pretty well at 200 meters. However, I am not experienced enough at using the Point Blank program (or any of the others I've tried) to figure out what the chart ought to look like. My data is as follows:
Temp: 59 degrees F
Altitude: 7000' ASL
Bullet Weight: 150 grain
Velocity (I don't know. All I have is the 180 grain stuff, but I think it's in the neighborhood of 3100 fps)
Ballistic Coefficient: I think it's about .508, but if anyone else knows for sure, I'd be much obliged.
I know it sounds like I'm a mouth breathing idiot for not being able to figure this out, and well...maybe I am.
Still, I've learned a few things over the years. Among them? When in doubt, ask people who are smarter than you! You all seem to know your stuff, so please help a fella out. Thanks in advance!
