[QUOTE="Fiftydriver, post: 1932082, member: 10"] As far as why you never see braggin groups from my personal rifles, never shoot groups. Some may find this hard to believe but its true. Only time i will EVER punch paper is if there is a problem with a rifle. So my personal rifle set up procedure goes as follows: at my shop, i will do load development by selecting the bullet i want to use, seat to within 10 thou of the lands, start at a safe starting load and shoot over the chrono, one shot for each load. increasing one grain at a time with most of my wildcats. Keep increasing and recording velocities until i see the first hint of an ejector ring on the case head or feel a slight increase in effort needed to lift the bolt on a fired case. then i will reduce that load by one full grain and consider that the max working load for that rifle. none of these shots are shot on paper, into a dirt stop. Then i will load up a batch of 20 or so test rounds at this level. I will take them up and test at a minimum of 800 yards to confirm load meets my accuracy standard. Once that is done, and usually its the first round i test. Not because i am that good, but instead because i have tested HUNDREDS of rifles chambered for my wildcats, so pretty well know what they like and dont like. so, once the load proves its up to accuracy standards, i will zero the rifle to be dead on at 800 yards. i will then run the numbers in my ballistic program which will produce a drop chart. I set the drop chart up for the zero range i want. Normally for my rifles i will zero them at 250 to 300 yards. so now, i have a drop chart, and a rifle i know is zeroed at 800 yards. Look up the drop chart and see what the dial up for 800 yards. For example say its 10 moa from zero to 800 yards. I would then take 10 moa out of the vertical adjustment. Set the scopes zero stop and set the turret to zero. then i will let the barrel cool completely and then take shots of opportunity at a minimum of 4 different ranges. For example, take a shot a 450, 600, 800 and 1000 yards for my lighter Stalker rifles. For my Raptor LRSS and XHS rifles it may be 600, 900, 1200 and 1500 yards to start. will take a single shot at each range from a cold bore just as i would in a hunting situation. Find a target of opportunity, range it, look up the drop, set up the rifle for the shot, take the shot and record the impact location for each shot. i will then study the recorded data. Many times, its dead on, other times i will need to tweak the drop chart and will do so until the drops match up perfectly with the actual point of impacts. once the drops match up over the entire range the rifle will be used at. I then finalize everything and from that point on, i will practice by doing practical field shooting just as was done to confirm drop chart. however, i may shoot 2 or three quick shots from time to time at a single range, if i hit on first shot, may be done at that range. never will i shoot at 100 yards, never will i shoot at paper and rarely will i shoot on steel. now realize these are hunting rifles, i do not need to know what the fifth or tenth shot will do as far as group size is concerned. not to mention, you put 10 round strings through most of my wildcats, you will get a new barrel installed at least annually. doing load development and drop chart testing the way i do, i can have a hunting rifle ready to take to the field generally in less then 40 rounds max. At times as little as 20 rounds from start to finish. once thats done, firing 10 rounds in practical field shooting verifying drop charts, will be much more valuable then firing 100 rounds on paper.
