Where are you at in barrel life?
Action screws, bedding, scope bases and screws: all good here?
How are you sizing brass? Did something happen to your dies?
Muzzle crown? Suppressor? No damage or built up carbon?

Screws are the next thing I’ll check and will probably happen tomorrow. Everything was loctited and torqued. Dies are Hornady bushing dies. Suppressor has been a scythe until it blows.

Oh shit, it’s probably just the powder switch then. Don’t fight it. The barrel will tell you what it likes. If you want small groups, shoot the H4350. If you want speed, shoot the N560.

If you want to keep working towards both goals combined, try another powder. N555 gave me 50-100fps over H4350 and still shot really well.

This - mine really likes N555

N555 at 42.2gr did well for me from my 18in barrel with 88s. Lower node is 3035 avg mv over 10 rds. Ironically it's the exact charge I run in my 25cm prs rig with 135s at 2870mv.
