[QUOTE="MajorSpittle, post: 696256, member: 53101"] I will be trouble shooting 4 things next time at range to narrow down what the issue is. I will start by shooting the same way that grouped well last time to verify I have a known good method, then take away each variable and see when the group falls apart. I will take away ONLY the listed methodology for each group, all else will be the same as the reference method. #1 Referrence group, From sled standing behind bench, each round hand loaded to chamber, 150gr fusion, barrel cleaned before each shot, 5 minutes between rounds and 15 minutes between groups. #2 Take away hand loading rounds and use Magazine #3 Take away cleaning barrel before each shot #4 Take away letting barrel cool, will take about 90sec between rounds due to cleaning between shots. will continue on firing after group #3 without pause other then to clean barrel. This way first round will be from warm barrel. #5 Shooting from sitting at bench off of sand bags. I don't want to change how I clean the barrel between rounds yet, but if I find that cleaning the barrel is what is allowing the tighter groups then I will definately get some good cleaning agent and try break in process if I can't get Tikka to take the rifle back and fix the issue. Best case senerio is that just one thing is causing a huge impact on group size. Worse case is that I find 2 or 3 things are causing modest variance that when combined create a large variance in group size. ie Chambering from Magazine, barrel temp, and dirty barrel combined cause a 1" jump in group size.
