So I'm at the range with 6.5 cm. Shooting 147 gr eld, SP Starline brass, 2.89" OAL 40.5 gr of H4350 and everything is fine. I decide to try the same load with 42.0 gr H4350. I have shot 41.5 gr before with no issues. I shoot and it's loud as $hit! My velocity was 2750. My ears are ringing hours later. I saw no significant pressure signs on the brass. There was a very faint ejector mark, but that's all. I wasn't sure what was going on. But I was worried I had went to far, so I quit the load. I've never heard of excessive noise being a sign of excessive pressure, but it still made me nervous. I suppose it's possible my headphones weren't sealed to my head. I went back and shot another group with 40.5 gr (2670 fps). Thoughts?
 
Shit man, I've loaded to 46gr of IMR4064 in 308 with 175vr nosler CCs with no pressure signs or extra loud problems. Just a moe solid boot on the shoulder.

I'd check to make sure your ear pro was fitting right
