Load Book vs Ogive

Load development, shooting diary and target analysis for precision shooters. Quickly add your rifles and bullets, then start setting up your loads. Add a new shooting session while at the range, retrieve the weather at your location or via your Bluetooth weather meter. Select your load and record your velocities for a charge test, or group sizes for a seating depth test. Close your session, enter your shot count, and graph or export your results for analysis. Load Development • Link bullets and accessories to multiple rifles • Auto-complete many fields including bullet, powder, case, primers • Store important rifle, bullet and load information • Powder Charge tests - record velocities per charge • Seating Depth tests - record group sizes per depth • Load Confirmation tests - verify consistency • Generate load strings automatically • Visualise through interactive charts • Tick off rounds as you load or seat each one • Progress testing through to approved to update your bullet • Flag loads as favourites, hot, reliable... • Automatic sweet-spot detection with explanation • Calculates your ES & SD and shows a precision flag • Export full details and graph as a PDF report • Connect your chronograph to capture velocities as you shoot: - FX True Ballistic - Athlon Rangecraft Shooting Diary • Quickly add a new shooting session from your location • Retrieve the weather or connect to your weather meter - Kestrel - WeatherFlow - Skywatch - plus many environmental sensing compliant devices • Live wind speed graph with 10 second average • Add notes from your shooting results • Add target photos to your shooting session • Tracks the loads you tested • Keep track of your rifle's shot count Target Analysis • Photograph your target or select existing photos • Add bullet hole markers, fine tune with popup magnifier • Group size calculation - MOA and MRAD • Saves results to your shooting diary and gallery • Zoom in, crop and share results with analysis overlay New Additions • Gun Safe - track all accessories and assign them to your rifles • Extra Information - Record you rifle's full setup for reference • Chronograph - Auto-selects first entry ready for velocities • Added SD bell curve chart to bullet details • Added Rifle, Bullet and Accessory popup views with Edit button Modern, easy to use interface.

Ogive is a ballistic calculator for long-range shooters, hunters and precision rifle competitors. It computes elevation and windage corrections for any rifle, cartridge and atmospheric condition, then trues them against the impacts you actually measured. WHO IS IT FOR? Long-range and ELR shooters working from 100 yards to beyond two miles. Hunters who need a field holdover corrected for altitude, temperature and shot angle. Competitors building dope cards and truing ballistic data against observed impacts. WHAT DOES IT CALCULATE? Ogive solves the point-mass equation using G1, G7 and custom drag models. It accounts for temperature, pressure, humidity and density altitude; Coriolis and Eotvos effects; spin drift and aerodynamic jump; powder-temperature velocity sensitivity; shot-angle cosine correction; and multi-segment wind with variable speeds and directions. Solutions are given in MOA, MRAD, inches, centimetres or scope clicks. HOW ACCURATE IS IT? The solver is checked against independently published trajectories rather than against itself. At 1000 yards it agrees with Hornady's own calculator to within 0.26 inch, and with Exbal to within 0.4 inch. WHAT IS IN THE DATABASE? 2,505 bullets and 1,943 factory loads, each read from the manufacturer's own published data with the source page and the date recorded against the row. 230 reticle models from Vortex, Nightforce, Leupold, Schmidt & Bender and others. 1,066 scope profiles with click-value calibration. WHAT FIELD TOOLS ARE INCLUDED? An interactive reticle view with computed holdovers at each hash mark. BC and muzzle velocity truing from observed impacts. Moving target lead. Maximum point-blank range. Full trajectory tables with custom range intervals. An Apple Watch companion, a Home Screen widget and Siri shortcuts. DOES IT WORK WITHOUT A SIGNAL? Yes. Every calculation runs on the device. There is no account to create and no network required to solve.
