Looking for assistance with load development for both Hunting and Target Ruger Precision 6.5 Creedmoor - 24"Barrel - 1: 8 twist - AimSport Silencer Lapua Brass - small Primer Pocket What Primer / Powder / Bullets?
 
For the 6.5 CM in the 140-143 weight bullets H4350 has been the "go to" powder. I have a 6.5 that shoots both the Hornady 143 gr ELD-X and the Beger 140 gr Elite Hunter into 1/4 MOA in front of H4350
 
H4350 and ~140gn bullet. Nosler AccuBond or Hornady ELD-X, but honestly if you're less than 300 yards the Partition is a great bullet also. I also use Lapua SRP brass - Fed 205M for extruded or a CCI 450 for ball powder.

Factory chamber, so I'd start at book COL or max mag length, wouldn't even waste time finding the lands.
 
Went with what was on the old hornady box. Lapua lrp fed 210m 41.4gr h4350 143eldx or 147eldm. Both shot good at 200. 1/4in for 143 1/3in 147. All the match bullets shoot well. Picked the 143eldx for hunting. My buddies tikka was liking 41.7-41.8gr of h4350
 
The old recipe from Hornady that they printed on the boxes were
41.5Gr H4350, 2.810 COAL and using FED210 primers.
Just used this recipe today and here's the results. The flyer was me but it's 5 rounds. Work up to that load as you may find something at a different load. 100yds.
