[QUOTE="NorCalAOSHunter, post: 2938129, member: 119142"] Finally got to Grouping today. I tested 2 loads that I had found "nodes" on in a ladder test: - 168 LRX, 68.1g H1000 COAL 3.20 - 160 CX, 71.1g H1000 COAL 3.29 I shot 3 shot groups. Let barrel cool to touch in between each group. Same setup for rest etc. I shot in this order: [LIST=1] [*]3 Factory 160 CX - Chrono with MagnetoSpeed to see what they were at, AND to heat up the barrel so my hand loads could be as "similar conditions" as possible - Note the Factory 160 CX: 2869, 2853, 2845 ... so essentially 2855 out of my rifle [*]3 Hand load 160 CX: Shot 1 & 2 were .099 MOA, 3rd shot turned it into a 1.265 MOA group [*]3 HL 168 LRX: 1.785 MOA [*]3 Factory CX: Shot 1 & 2 .290 MOA, 3rd took it to 1.091 MOA [*]3 HL CX: Shot 1 & 2 .216 MOA, 3rd took it to .622 MOA (I am noticing a trend here, not sure of ammo/rifle or shooter getting lazy on #3) [*]3 HL LRX: 1.722 MOA (confirms first group) [*]3 HL CX: At this point, I knew the CX was the load for this rifle until I can get some diff powder to try with the LRX, because I WANTED the LRX to win. Slapped the MS Chrono back on and: 3010, 2974, 3011 ... Avg ~3000 [/LIST] So at this point, since I want to bear hunt with it, I am going to stick with the 160CX. I will load up another 100 and do some more shooting and chrono to get better data, and to see if the 1,2, then 3 issue is a shooter or rifle issue. Primary Load: 160 CX @ 71.1g H1000 and COAL 3.29, ~3000 fps out of a 20" Carbon Six barrel. Now to Zero with that load, as you can see my impact and POA were consistently off.[ATTACH type="full"]507355[/ATTACH] [/QUOTE]
