Quickload question

[kycamtrakker]

i have it and i loaded 47gr of RL25 with a 115 DTAC and my gun has 26" 7.5twist brux barrel and its 243win. Quickload said i should get 3005 fps and my chrono only said 2770.... is there something wrong or could my chrono be off that much???

SIR: QL is an interactive program----so garbage in garbage out, no magic...Suggest you vary the weighting factor [normally at .5] then continue to run your other parameters until you get a QL computer MV close to the one that you observed using your CHRONO.....This will customize your use of the QL programming to your specfiic rifle and load...[all else being equal]. See the QL tutorial in 6mmbr historical blog...I have been using QL for a long time and if you take the time to make certain parameter inputs you might be surprised how good it gets....BE WELL....Good luck and keep the faith....V/r mk
