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

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
-
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!!! :yike:
-
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?
-
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.
-
My guess is to hot. I have seen marks like that when playing on the upper end of loads.
-
The primers don't look that bad to me--the edges are still rounded. Does that ejector mark occur with all brass, or just Lapua brass? That's a pretty big case. I'm told Lapua brass is softer than others, but I don't know from personal experience. Never used Lapua brass....
-
Look at the peened mark in the base from ejector pin. :yike:
I know of 2 788 Remington in 222 both shot the same load one needed a 2x2 block to open the bolt and the other just fell open. Just the differance in the chamber.
-
When I first got into the short mags and started playing with them I had a 270wsm that was a 700, that sob would not the brass with the ejector pin on almost every load. Alway drove me nuts. Most were not to hot, but some has some zest :chuckle:
I would say back it off and look at your COAL as well.

It looks like the ejector isn't flushing with the bolt face, and the brass is pushing into the ejector channel. maybe the ejector is too short? I think I'd send the gun back to the manufacturer with a fired case so they can see what's happening. If the loads were really hot, the primers would be flattened right into the primer pocket, and be hat-shaped when they are pushed out by the decapping pin. :twocents:
-
you may want to try 51.5 of rl19 , fiffty thou off the lands with 140 vlds.
-
has anyone ever tried retumbo?
-
Sorry not a cal I rebuild!
-
Another thing you might check is the thickness of the case necks. The neck has to expand a tiny bit in the chamber on firing to release the bullet. If the neck is a tight fit in the chamber, it may take more pressure to release the bullet. You may need to neck-turn a scosh off your case necks.

:yeah:
I agree. The other thing you might try is another primer. I have had alot of problems with consistency with those damn CCI primers. I have had the best luck with Federal and Winchester. :twocents:

Just because it's under max listed load does not mean it's not to high for your gun. Looks like ejector scuff and flattened out primers. I would try a different powder if you where not happy with lower loads. Also maybe a different primer.
