6.5x284 question wierd thing happening? Help!

[wablkandtan]

Cannot figure out why 2 6.5x284 savage lrh are doing this.
My loads are under max. 
51g n-165 help
Lapua brass isnt cheap.

Looks like over pressure to me, but pic is pretty blurry.

Dirt in or obstruction with ejector?  The rest of the round doesn't appear to look peened.

Ive got some rounds that get messed up and some that dont.  I also have 2 of the same guns and both do it.  The gun did have a bad extractor spring and was replaced. 
Still doing it.

have you checked make sure you are not seating to deep it can cause the pressure to change

Or not deep enough--like right on the lands?

I just talked to my gunsmith/reloader guru.  He said that you're most likely running your loads hot even though they aren't up to max. He said if your not splitting cases, having primer problems, or bolt lift issues, you're probably ok . He said to lower your powder and try that.

Looks like an ejector slot marking....Use your chrony to find out where your max load is clapping out in velocity and back it of 2 grains from there.. Just because your getting the marking doesnt mean its to hot

[wablkandtan]

ok ill try that but i wasent getting awsome groups till i hit 51gr.  has anyone else reloaded a different powder for this gun?

Hammered flat primers are not a good sign in my book!!! 

[wablkandtan]

hammered flat primers?  is my load too hot?

hammered flat primers?  is my load too hot?

If that was my gun I would back it off.  Is the bolt hard to lift at all after you shoot?

[Ridgeratt]

Just because the data says it's not max doesn't mean for your gun it isn't! that's why they recommend backing off 10%
Most of my loads I build are always less than max. I get longer case life and better accuracy. I'm sure many will take exception to this but just what I have found. I'm just learning only been reloading for close to 40 years so it's still new to me.
