Quick Load problems

[edw]

I have just started playing with my QL program. I first tried my Creedmoor loads and I found QL pretty damn accurate to my bench results using Lab Radar for speed. I only had to tweek my burn rate (ba) less that 1%. When I plugged in all my parameters for my my 6mm Dasher things didnt align at all. In order to get QL to agree with actual data I would have to tweek the ba at least 7%. Its been written that ba should not be altered more than +or- 5%. I wonder if QL does not understand Sierra's new 110smk? I'm out of ideas.

Have been using QL for quite a few years and have always been able to get it to match my data. Some with very little work, some with a substantial amount of effort. I know you have probably already done this but recheck all your inputs. Barrel length, cartridge oal, bullet oal, your actual case H2o capacity. If you're still off adjust your Weighting Factor, you can also adjust your bullet weight slightly. I have some very cool lots of powder as well as some very hot lots of powder and in some cases the Ba has to be adjusted substantially but I don't believe I have ever adjusted more than about 3 or 4% in most cases it less than 2%. Remember it's very important to match the temp. to the day you shot the loads. That's all I can think of off the top of my head, if you continue to have trouble, you could PM me all of your data and I could run it and see if I have the same trouble that you're having. Good luck and let us know how you make out.
