This was surprising when done.

My tune kit for the HW97K came today, was able to put it in and run a couple hundred pellets through. Zeroed it at 30 yards. Velocity was 819 ft/ps with JSB 10.34.

Ran the info through a ballistics program for a range card. Will verify tomorrow. This was a new program to me so also ran my PCP used for FT to compare to the old program. When both were printed out they are almost identical. Both have the same scope a Hawke Airmax 4-16 old one. Really surprised me in a pleasant way.

That's great if things work out that way, but I would expect some differences will pop up under real world testing. Scope height and BC are the biggest factors when making a range card. With springers, I have to shoot a bunch from zeroed yardage down to 10 yards to figure out what the software thinks the scope height is versus what it is measured to be.
I have 2 springers and a PCP all shooting the same pellets at the same velocity. Using the same scope (and the same rings) on all 3 guns, I get 3 slightly different range dopes due to differences in the perceived scope height. Each gun has different receiver heights, or droop, or something.

IMO and personal practice ... NOT accurate enough !!

If D.O.P.E. states a 1.7 mill hold, using a 1.5 is not good enough :oops:
As for any hold point that is in 10ths needs to be held and shot to that fractional POA ;)

Those of us who have had years in the game playing at the State or National champion level ... WE LIVE & DIE on utilizing accurate dope data .. and those wishing to see just how well you can shoot on an FT course are best served being as exact in POA as one can muster.

Shown is a D.O.P.E. card made up via Chairgun. It is IMPORTANT to use a very small PBR / ZERO range. * If you have your PBR at .3 so will be the entire data +/- be .15 at all distances & will give you possible splits ........ I use .100" ZR which is +/- .050" AND ONLY ONE Zero range, NOT two !!

Make note that the hold over data is to the 100th .. it can be rounded to the nearest 10th ( All one can hold anyways ) as in a .73 being .7 or a .78 being shot at .8 etc ...

Understand garbage Kinda close data in, results in garbage kinda close at target results .. You Can Do better ;)

It's been a while since I shot hold over, but Motorhead's level of precision is difficult for me to attain with my current "hunter" scopes. What I used to do for anything further than 25 yards is calculate to the nearest half of a mil, and mark an H or L to tell me to hold high or low. So -1.3 mil would be -1 H. -1.4 mil would be 1.5 L. Anything 25 yards or closer, I would try for .25 mil data, since that is the limit of 1/2 kill zones and it's easier to get that level of precision under 25 yards.

Not trying to take away your relaxation, but I feel that hitting targets is more fun than missing targets. And I've got a ton of experience missing targets to base this on.

Do take notice that inside my zero distance ( 25y ) the holdover to @ 20y only changes a little, but 19y to 10y you better be paying attention and holding correctly to avoid 12 & 6 o'clock splits.
Also take note from @35y on out EACH YARD further picks up about a 1/10 mil in required hold over. Here again rounding out to the nearest 1/2 mil hold point is not going to cut it or support much confidence when targets are not falling ;)

All I can do is share the degree of precision D.O.P.E. data I've been utilizing & applying for years now hoping others can see the value in having it.
For those who take this FT game very seriously, The next use of precision data / dope is when your just not sure or able to get a good parrilax focus and distance figured out ? Here you now can determine if the target is closer or farther than you are ranging and if or not does any distance correction In/Out with there known hold point of the alternate distance still fit inside the KZ ?
MASSIVE !!!!! piece of data is now at your disposal, should you choose to use it (y)

All this and other Ranging / POA tricks has served me very well in Local, State & National FT shooting events.

Motorhead how do transfer your written dope to your visual reticle field? Isn’t there a smiggin of guess work? I start with StrelokPro then verify each shot at every yard from 10 to 55 yards - zero range not so much.

The printed out D.O.P.E. values are held "In the Moment" and use no superimposed hold / reticle picture.
Range it, think about if parallax snapped in or not ?, Size up the wind situation .... Resolve a POA and just shoot it.

STEADY is key and the biggest struggle ANY FT shooter has too get a handle on pending class & aids afforded :cautious:
