I used the previous program for several years with fantastic results on first shot in the black results many times at 600-1000yds. I will continue to use this exclusively as it is as Laurie pointed out “spot on” with berger bullets.

The previous comment should have said 500-900 yard come-up. As an excuse, I’ll say the Holland #3 cat stood on the keyboard – she likes to help. Yes really, this is not a “I did my homework Miss, but the dog ate it” excuse.

This is one REALLY useful facility. I already have Bryan’s Applied Ballistics “Point Mass Ballistic Solver V2.0″ software but the ability to tap into the Berger Bullets’ database is very useful. I ran it today with a 0.308″ 155.5gn Berger BT Fullbore load over IMR-8208 XBR that I used in a 900 yard F-Class match and the 500-800 yard come-ups were absolutely spot-on.

Before anybody says anything, the adjuster values on my Sightron SIII 8-32X56 LRMOA scope were chscked for accuracy, so we’re talking real elevation changes.

The one thing lacking in the online software is the rifling twist drift factor which the PM Ballistics Solver had calculated as 0.6-MOA at this distance for the 155.5 in a 1-12-inch twist rate/. After allowing for this, the actual average ‘corrected wind allowance’ was very close too for the Berger program’s calculated wind drift for the conditions experienced – zero degrees C (not much spring here in the UK on the second last day of March!), a range c. 900 ft ASL, headwind from 11 o’clock running at 5-15 mph taken as a 10 mph average.

As well as manufacturing superb bullets, yet again we have to congratulate Berger on its supporting services.
