[QUOTE="jerrschmitt, post: 266156, member: 16076"] And that's where we agree 100%. In my view the computer programs are great for predicting what a bullet will do at a given range, at a given temp, altitude and wind. Like you, most of my loads were worked up many years ago and still do just fine. The one change I have made was to use VMAX bullets in my different Varmint rifles. The change in BC required new dope sheets. I plugged the new numbers into my computer and took the results to my local 600 yard range. The firing results did not match the computer model so I adjusted the BC and MV input until they did. My favorite Dog town is 2000 feet higher in elevation than my home range and usually 50 degrees warmer. When the new dope sheets were adjusted and applied to that dog town I was in the ballpark. I still had to figure the range, dope the wind, work the mirage and pull the trigger. [/QUOTE]
