Maybe it's the heat of your bbl effecting your 3 shots, or antisapation or a change in position slightly ,But your first two are very consistent ,which is Great shooting ,hold &follow through . Your shooting down hill verses flat which I'd think would be easiest ,and uphill equals down hill ,but your Still very consistent 2 out of three so that is very possible Mute point . Those factory ttsx are ausome your BBL is grooving on them , that weight mite be King !, There's quite a powder charge difference wit H1000 between the 168 LRX & the 162 Eld-x advantage goes to speed with Eld-x , Great combo with 160 accb n imr 4831, great shooting and yur Rifle likes it !!! . Rl/22 didn't do to bad , one bullet. Little out , still good shooting , maybe h1000 is to slow wit the LRX 168 , mite try imr or rl behind it . Your the Boss but some bbls like different weight bullets pruffs in your pixs, Your still way ahead of the Learning curve , Congrats & Thks for sharing with US !!!.
