[QUOTE="RDM416, post: 123066, member: 3745"] I just got my copy of Xbal in a few days ago and began loading data into it. Although it is closer than other ballistic programs I have used I am having problems getting it to match up with the real world. I am shooting a 338Kahn with 250grn SMKs at 3170fps. Sighted in exactly 3" high at 100 yards. Using a NF NXS scope. I have shot on several occasions at 100 yard increments out to 1000 yards. I have refined my dial up chart to the point I am very confident in it. When I plug in all the data Xbal agrees with my dial ups exactly out to 700 yards. At 800 and 900 Xbal tells me 1 click more than my chart. At 1000 it tells me 3 clicks more than my chart. Am I just being too picky? 3 clicks when you are talking about 70+ clicks is not much, but 3 clicks at 1000 is enough to miss a deer sized criter. I can adjust the BC from .587 listed by Sierra to .610 and I am on at 800 and 900 and 1000 is only 1 click to high. Any words of wisdom from all you that have been using Xbal for a while? [/QUOTE]
