[QUOTE="Eaglet, post: 880589, member: 3756"] ColdBore 1.0 comes in 3 editions, which is a platform wide offering that neither AB or Horus can match, since it’s available for the PC, PDA and Windows Phone platforms. In terms of features, nothing comes close to what the software offers, neither AB nor any other package on the market, as can be verified jus by checking the respective vendor’s websites. And for pure ELR work, the predictive accuracy of our CB1 Ballistics Engine is unmatched too. For anyone interested, please check this link.

A long thread was posted in Sniper’s Hide by Lowlight regarding this test. Sight-In Conditions Baro Pressure = 24.76 Temp = 23ºF Humidity = 53% Alt = 4639 Feet Field Conditions Baro Pressure = 30.30 Temp = 15ºF Humidity = 46% Alt = 4639 Feet Ballistics Parameters MV = 3118 fps BC – G1 = 0.890 (DTM data) BC – G7 = 0.433 (calculated, not published data) DC = 0.500 (ColdBore 1.0) Click Setting = 0.102 MRAD (ColdBore 1.0) BW = 352 gr ZR = 100 yards SH = 2.0 Inches WD = 150º WV= 6.0 Mph Lat = 40ºN (aprox) Az = 001º Litz’s program does not use BARO, so the STAT pressure was set at 25.55, yielding an Air Density of 0.07133 lb/ft³ which is the exactly the same as for using a BARO pressure. Ballistics Predictions as yielded by 4 different programs CB1 = 40.7 MRAD Litz – G1 = 37.3 MRAD Litz – G7 = 39.7 MRAD JBM – G1 = 37.1 MRAD JBM – G7 = 39.5 MRAD FFS = 39.6 MRAD From the DTA HTI test the following value is considered the TRUE adjustment to hit the target. Elevation Adjustment Required at 3080 yards (2816 meters): 40.8 MILS So at that range 1.0 MRAD =>> 3.08 yards = 2.816 meters = 110.88 inches = 9.23 feet Now, the LINEAR ERROR for the different predictions are as follows : CB1 = 40.8 - 40.7 = 0.1 MRAD =>> 0.28 meters = [COLOR="blue"]11.08 inches[/COLOR] = 28.1 cm Litz - G1 = 40.8 - 37.3 = 3.5 MRAD =>> 9.86 meters = [COLOR="blue"]388.03 inches[/COLOR] = 985.6 cm Litz - G7 = 40.8 - 39.7 = 1.1 MRAD =>> 3.10 meters = [COLOR="blue"]121.95 inches [/COLOR]= 309.8 cm JBM - G1 = 40.8 - 37.1 = 3.7 MRAD =>> 10.42 meters = [COLOR="blue"]410.24 inches[/COLOR] = 1042.0 cm JBM - G7 = 40.8 - 39.5 = 1.3 MRAD =>> 3.66 meters = [COLOR="blue"]144.1inches [/COLOR]= 366.0 cm FFS = 40.8 - 39.6 = 1.2 MRAD =>> 3.38 meters = [COLOR="blue"]133.08 inches[/COLOR] = 338.0 cm NOW MOST OF YOU WOULD KNOW WHY, NOT BEING AFFILIATED IN ANY WAY TO Patagonia Ballistics, I use COLDBORE 1.0 [/QUOTE]
