Seating deeper usually increases pressure.
Sounds like he's getting pressure signs at starting loads. In any case seating deeper generally increases pressures. That's my stance and I'm sticking to it.I talked to Steve he thinks seating deeper to because I’m getting pressure signs at starting loads but getting bigger charges velocities
Maybe post some pictures of your pressure signs. Do you have any case lube remaining on your cases, that can cause flattened primers. Do you have ejector marks on your cases? What's your velocities?I’m going to double check the chamber. But a run a latter test yesterday and didn’t see pressure till 41.8/42.
Well it does sound like pressure signs. I'll stick to my opinion that seating deeper will generally increase pressures. So you could decrease the charge and seat deeper. Or you could try a different powder. But another possibility is your throat. You could have carbon build up or some roughness. If you could get some JB or Iosso and polish/ clean the throat a bit that might help.Velocity was about 2715 at 41, I wiped the cases down pretty good with a rag. There is ejector marks.
I haven't run Hammers, but my little Savage M10 308 Winchester 22" has always ran on the hot side with loadings.Velocity was about 2715 at 41, I wiped the cases down pretty good with a rag. There is ejector marks.
