All rounds shot from bipod with rear bag by average shooter who is still learning (me) so there are a couple I know I pulled and have excluded those from results

Prep
130 Sierra tgk
H4350
Cases full sized - shoulder bumped 3 thou
All bullets seated at the same depth +/- 1 thou
25 thou off the lands

Previous round of testing was from 41.6-44 in 0.3 gr increments showing good results from 42.4 up

loads tested
42.4 gr best group
42.6 gr reasonably tight but a bit laddered
42.8 gr shit show of a group
43.0 gr
43.2 gr tight bolt lift

My thoughts are stick with 42.4 then start on seating depth - What do you all think?

My thoughts are to load up a box or two of ammo and go hunting. Save any further load development until winter and early spring. Your 42.4 grain load is close to max in the Nosler data and over max for a Nosler projectile in the Hodgdon data. Your Sierra projectiles are a little softer but not that much. Get that chronograph sorted before you next test session. Your groups are great considering your equipment. It ant broke so don't try to fix it,
