WILL you answer questions on youtube? 2 voicemails and 2 emails still not returned? question-- my bullet was in the app library, a 142 smk. when i chose it, it says doppler for bc, yet in your earlier video, yours stayed on g7. question 2 -- i used a labradar for chrono, so if i true the profile, i should pick bc? even if it says doppler? and even if the bc is obviously a custom drag model in the library? the solution seems to be off at 1100 yds, 2.5 ish moa high.
If it helps, here is my experience with the Revic App. If the app has a doppler profile it will default to that, if not it will use the g7. I would say use what ever works best for your rifle. IE try both. Typically the doppler will be more accurate, but it is still an assumed model from lab tests of that bullet make/model. You can still adjust it to fit your rifle/barrel. I adjust the "BC" using the doppler profiles all the time. It just changes it as a percentage of the assumed drag model (more or less drag). Again, that has been my experience, take it for what its worth.
@@ExtremeTargets thank you. would you mind a couple more questions? i notice in the ballistics part of the app, i have to actually "turn on" spindrift, earth and jump. do you know if these things are calculated by the ballistics in the scope? question 2- have you used the powder factor and powder temp functions on the bullet profile? with the ammo i am using, i have noticed a swing in the average mv at 78 deg (mv=3103) to 92 degree (mv=3125). i get all weather info from my kestrel elite, the temp was the only that changed from those 2 different sessions, one was morning and one was early afternoon
@@kevinlowe7552 I believe the "earth" effect setting are just for the "in app" calculations. I think the scope/devices will always include those factors as long as you provide the wind vector (as that is a required input for some of the calculation). On the powder factor, I've never personally used it as most of my loads are minimal or I get the mv for the conditions I'm shooting in. But it does seem your current load has about 1.57 fps/degree change (fairly significant), so it would probably be worth setting it. Set the temp that matches the MV you entered, then put 1.57 in the powder factor (22 mv delta / 14 deg range) and see how it goes.
So based on your opinion about first focal plane scopes, why bother manufacturing them with elevation and windage turrets that give 50+ MOA adjustment? All you would need is 10 MOA maximum to establish a zero then use your hash marked reticle to aim off.
I see you have a SiG Sierra 6 scope there. Good high tech scope that uses Bluetooth from a laser rangefinder and a KESTREL 5200 Elite weather meter. I'm getting the new BURRIS Eliminator 6 that will do all of that but the wind, plus it has ED glass. The Eliminator 6 references your weather conditions THE DAY OF SETTING THE ZERO. ALL HOLD FOLLOWING SOLUTIONS ARE BASED OFF THE ZERO DAY CONDITIONS. Hence "ZERO ANGLE". Finally, for me the HORNADY 4DOF ballistic engine is THE most exact one yet devised and gives me the MOST CONSISANT firing solutions. It is that consistency that convinced me of the superiority of 4DOF over mathematically built ballistic engines.
With a standard zero as soon as any environmental changes from when you zeroed the rifle is no longer "zeroed" according to the ballistic calculator. A zero angle finds a fixed angle between the scope and bore than never changes. A zero angled rifle is the same in Alaska as it is in Utah. If you have a 100 yrd zeroed rifle in Utah it will be a vastly different zero in Alaska.
Why not just do what Strelok does, and have all the environmental factors for when it was zeroed? Won't that do the same thing or am I missing something?
Vector wind would be measured typically with an anemometer (wind meter like a Kestrel type device), or estimated if you're capable. A vector wind simply consists of a direction and a wind speed.
Excellent question! Only the elevation turret reads out in the HUD. We have found that in most use cases, our customers/shooters are choosing to hold for wind instead of dial.
Honestly some of the most interesting products for range shooters & hunters, but I can’t imagine I would ever be able to afford the products. I mean the amount of effort put in to create a series of products that add a significant benefit when combined is impressive, but each individual product holds its own alone too. No denying that these are a functional step forward compared to the current standard of ballistic tools, and easy to imagine that the future base of hunting, shooting sports, and all the equipment in between is being introduced by the solutions REVIC included in their products. It’s just unfortunate that the products are pretty out of reach for the target demographic that would benefit most from having. I hope their future progress continues as I’m excited for what’s next, but also over time the price may drop out of purely a dream for the average hunter like myself.
It automatically calculates for altitude and any other atmospheric conditions such as temp, barometric pressure, etc... and It is available in Mils or MOA with a selection of different reticles. The PMR428 is a first focal plane scope. Learn more here: www.revicoptics.com/product/pmr-smart-scope-rifle/
