Rather than bumping this up, I found a cure so far. It seems the ADG brass wasn’t showing me signs like I’m use to seeing in other brass. I re did a ladder test and found a nice node 2 grains less then what I was using with a speed about 90 fps slower ( went from 64.4 gr H1000 and 3030fps to 62.5gr H1000 and 2940fps). I used 2-3-4 times fired brass all re sized and trimmed. My ladder went from 62gr to 64.2 gr, 64 and 64.2 both gave me clicks /heavier bolt. Anything under that ejected perfectly.


Hey there all,

I have a 7 Saum Iv been shooting the past few years, same load, same components, 64.4gr H1000 behind a 168gr VLD and using ADG brass and a standard rifle primer.

I can get 2-3 firings before I notice the heavier bolt, with a heavy click as it hits the end of its up stroke, if that makes sense. I’m not seeing any big pressure signs at all, so I don’t think I’m over pressure. The first couple firings have no heavy lift or click at all.

I’m using a cheap hornady sizing die without the expander and then run my brass through a mandrel.

I’m wondering what the first thing to try and change would be? The sizer die? Or the brass?

I measured at the .200” mark as Iv read in a couple places. I seem to get about .001 or so difference between fired and sized, iv read it’s not enough? This has me wondering if I should first try a new sizing die?

Any input or ideas would be appreciated :)

Put a little dab of gun grease on your primary extraction cam point. It sounds like your primary extraction is working a little harder than it should. Back when I neck sized only, I found that after 3-4 loadings it was harder to work the bolt. After full length resizing this went away for another 3-4 loadings. You could buy a Redding Body die or take a couple thousands if an inch off your shell holder.

I will add a dab to that cam point, it’s a good idea anyway I’d think :). It’s a deviant action, all in all it’s a pretty smooth cycle even for the first 2-3 firings.

Iv read about a body die, but if I can keep it so sizing the body and neck at the same time, it would save a step in the process.

I’m tempted to buy a Forster or Whidden die set, but it’s a lot of money if it won’t help the issue. I have a handful of shell holders around, I may try filing a hair off then re sizing and re measure the base.

Whiddens are fantastic dies, I use them for both my .223 and 308 match rifles🙂

Measure your shell holders, you might find one that is .001"-.002" shorter, not all makes are the same. You can also run a few of your loaded rounds thru your body die to see if this solves the problem.
 
Thanks guys.

I was up at the range today with a few loads I had ready to go with new brass run through a mandrel, plus some once fired brass, sized and reloaded.

The new and second firing was smooth as can be, second firing did seem a tad heavier maybe on the bolt but not really noticeable.

The 4th firing brass, I only fired 2 rounds today because of the tight bolt after. I will have to pull the leftovers from last summer apart. They would have had the proper case prep and same components.

I bump my shoulder back .0025-.003 thou and stay on top of trimming.

The carbon ring, iv read about a bit. I don’t have a bore scope to inspect it, iv read its best not to own a bore scope.. (kidding of course). It might be something I should invest in here.

I’m curious to play with my shell holders here and see if there is any variation. I may experiment with shaving one down a bit.

I appreciate the feedback guys.
 
No expert here but I’ve read and had a little experience with this. It’s supposed to be a pressure warning nearing peak pressure with the new short/ fat/steep shouldered cartridges popular today. Non the less, strange it only happens with the multiple fired brass. I wonder if you reduced the load slightly in those brass if the clicker’s disappear?
 
No need to pull your last years ammo apart. Just run them through your body die and see if they chamber. Remove your firing pin first and you can do this in your loading room with having to wear hearing protection.
 
Mic the web of new brass,once fired,twice fired etc prior to sizing.
The measurements will be all that is required & then F/L size to acquire the web measurements to fit in said chamber.

Instead of bastardizing shell holders, if needed face a few thousandths off the bottom of the size die.

I’m in the lower node I had found at the time I did load development, but my barrel has sped up 30-40 fps on average I think, now that I think about it. I have 2990fps in my notes, but today I’m 3025 as an average. I wonder if dropping back to below 3000 would change anything.

Iv never removed the firing pin on one of these deviances, if it were an old model 70 it would be no issue lol. It’s only dozen or so rounds.

I will check my brass out :)

Bastardizing a $12 shell holder is cheaper than trying to facing off and maybe screwing up a $100 die, but that's just me.
