How many of you still use dope cards, instead of ballistic calculators?
I love my tech but I still always have them with me.
While computerized gizmos are really nice for what-if scenarios, I keep and use a dope card for my F-class rifles.
I have one taped to each my rifle's stocks once I have a load for each rifle that will be that rifles "go to load".
I use my phone ballistic calculator to make up a range card based on the weather that day. If you shoot all seasons with temp swings then one set of dope won't work very well. Not to mention changing BP, elevations, etc. The dope stays in my range book for reference, but again with a significant weather change you better know how to compensate especially at longer ranges.
I should add that my cards are for the average temperature during hunting season and only out to 500 yards. I just need to hit an 8-10 inch circle so any changes I can compensate for by adjusting my hold.
I do have a calculator on my phone but don't truly trust them with out verifying them.
I used to. Then I switched to dope note card. Basic dope just a few distances Like 400 600 800 1000 yds. No wind or anything like that. Now I have shot my hunting rifle enough I usually do not even use my calculator any more. Unless it is angle shooting or if I really go up or down in elevation.
Electronics are nice but they cannot work as fast as a DOPE card in the field. Learn to use both and you'll be better served.
I just write it my shooting mat with a sharpe.
Looks like the Joker card has been replaced.
unless I am going out past 600 yds the dope cards; @$1 apiece beat the heck out of the Kestrel. I also have a set of Leica Geovids with me.
I use a dope card with a base line trajectory from 600 to 1200 in 100 yd increments. (2000ft, 70 degrees, 28in Hg). I then write in my increment of change per 20 degrees temp at each yardline. And my changes per 1in Hg. I have to do a small bit of mental math but it's easier than pulling it out of my butt when equipment goes down.
0-600 yds there isn't enough change to really worry about unless shooting targets approaching 1 moa or smaller.
Dial-up's to 1500 yards in 25 yard incruments. Wind dope to 1500 yards from 5 mph to 30 mph. Hold over yardages. Plus I have the Shooter App.
