[QUOTE="jdavistx, post: 1632630, member: 89418"] 1/2 MOA difference at 100yards based on environment? Maybe. 1/2 MOA is 1/2" @100. 40deg temp differential. Temperature of your load? Humidity, ? vs drizzle. 2100 ft altitude differential. Indoor (bencherest?) vs outdoor(?). Wind? I'm not saying that's the problem but they all add up. However, to answer your question directly there are some really good programs out there. I happen to be a big fan of Brian Litz - Applied Ballistics. It doesn't come cheap but there are some free ones on the web, although not as good. I use a Kestrel to collect my data. If it's not the gun or you (sorry), take the environmental conditions in both places and run them through a ballistic calculator. That will give you a clue. I live in Texas and elk hunt in Colorado. Sometimes some weird stuff happens and I have to chase it down. Last question: Is this factory ammo or handholds. Sometimes you get strange results from box to box. The biggest opportunity for me is to make sure that I shoot 0.004" off the lands. So I do handloads. Like your choice of weapon I shoot a 7mm Rem mag and use 168gr hunting VLD's from Berger. 2995fps. 0.258 MOA. I wish you well in your search for the solution. JD [/QUOTE]
