Re: DROP CHART . When EXBAL FAILS ???

One thing I do is always shoot the same bullet weather I'm shooting prairie dogs or whitetail deer. This takes another variable out of the picture with a custom turret.

Here is something which might be worth looking into if you want to save money and want to use different loads for one rifle

Everything I need to know out to 1500 yards.
Dial up's in MOA every 25 yards.
Wind dope in MOA every 100 yards with wind speeds from 5 to 30 mph
NP-R1 retical holdover chart.
All set for my hunting elevation and within Plus or minus ten degrees f of the temp.

I usualy have my Shooter program and Kestral 3500 with me...but not always.

Print those drops.

If you can do it at different elevations conditions and make up multiple cards.

One thing you can count on with technology is that it's only likely to fail you when you need it the most so always have a backup plan.

As stated above if you go with custom turrets you can get them for different bullets, different elevations/conditions.

While we try to narrow the variables and unknowns as much as possible for precision with the high speed calibers we are shooting today combined with the high BC bullets a change in conditions (other than wind) usually isn't going to make or break you out to 1,000yds.

Beyond 600yds, life gets complicated but controllable, beyond 1,000yds, life gets extremely complicated so you want everything as exact as possible.
I do the same thing, JBm balistics has a handy drop card that allows you to have up to 3 sets of variables on 1 range card, printed out their not very big either. Laminate it, fold it up and stick it the pocket of this

Being competent with a given rifle is far more important than impressive ballistics and poor shootability. High velocity misses never put a steak in the freezer.

Re: DROP CHART . When EXBAL FAILS ???

I have used yardage turrets for the past several years now. While I have turrets for the locations and typical conditions, I also have committed to memory click adjustments for relevant temperature and altitude variations in a given location which is1-2 clicks for each 1000 ft or 15 degree change depending on distance. This has worked well and is fast. This past season I used a G7 rangefinder that compensates and gives a yardage correction for any turret program I enter. It works so perfectly and I so fast it almost feels like I'm cheating. For back up I always have my Geovids and traditional equipment and technique. Since my yardage turrets limit out at 1000 yards which is my limit on game, if I want to shoot targets or coyotes at longer ranges, I switch my turret to MOA, or will just use come-ups from the 1000 yard mark on my turret. I like the idea of the turret from G7 Nightforce from Gunwerks that has both yardage and MOA on the same turret. I just mounted one on a 338 I'm working on but haven't had a chance to set it up and use it yet.

Rea: DROP CHART . When EXBAL FAILS ???

I have been using a prototype I developed that makes field range cards a lot easier to read and use still looking for the best way to show it to the public and not get hosed out of my idea
