DUD Remington 7.5 small rifle bench rest primers

[skeeljc]

Nothing wrong with the primers you got primer pocket issues. Are you seating them according to feel or depth? You can see the misfired ones are deeper than the fired one

The thread started to derail here.

You cant kill primers soaked under water or oil for months

Thread completely derailed here.

Sorry about that, I missed it. Post corrected

I sometimes have to grind down the bottoms of my RCBS FLS dies down to get them reach my shoulders at all. Also, I don't think I've ever had new brass in any caliber that was not slightly shorter than the HS dimension I considered optimal. As noted, it takes a firing or three before they are stretched out to where they are too long.

Why would you not relieve the shell holder instead? $80 die vs $4 shell holder.

The primer indentations in the photo appear to be plenty deep enough. It can be hard to tell with a grainy photo, but they do appear to be fine. That made all the headspace/which rifle/which die/primer seating, etc. questions snipe hunts for Nic to go on. He certainly does need to learn about all that, but it was not his problem. He did not do a bunch of things wrong, as he was accused of, he did one thing wrong -- failing to completely dry out his wet brass before priming and loading.

Because I often use the shell holder with multiple dies, it is easier to grind down the die, and because grinding it down does not impair the die's use in the future -- it merely makes the die be how RCBS should have made it. HTH

I had to relieve a shell holder for my Mighty Armory die to work, and I still use that same shell holder with ALL my other dies as well. The bottom of the case head is the only thing that touches my shell holder, for any operation.

@Tokay444 , sometimes correcting the die which admittedly is more effort, makes it so that it doesn’t become a mistake if you pick out that die and use it with any other shell holder.
The extra effort is to prevent a mistake. Your point is a good one in that if you don’t have several shell holders always laying around and there is no opportunity for this mistake, it makes sense to tackle the problem with the shell holder.
After a lifetime of accumulation, I probably have a dozen for the 30-06 size case head, which covers many calibers. As a result, I have had to dispose of some and rework others in order to get them all to spec.

 

[Tokay444]

I never subscribed to the die needing to touch the shell holder for any reason.

 

[KY_Windage]

It literally takes me less than a minute to grind a die down. I don't see how grinding down the shell holder could be less effort. The die is a lot easier to hold than the SH is.

@Tokay444 the tooling philosophy taken should consider it as a method for bypassing stiffness issues with many presses. If a process is stable without it, then no worries. But, if a process is perturbed to the point where the low stiffness of a press load chain means that if you don’t bottom the die you get a poor result, then why not bottom the die.
I always teach to learn both ways and more importantly learn why and when to use each philosophy, then step back and let folks do what they like.

Thanks.
I haven't encountered such a scenario yet, but perhaps in the future I will.

Time wasn't even a factor in my decision, and both chuck up just as easily.

LOL, there is no "chucking" in my grinding.

If the primers had gone off as normal, then NONE of the bullets would still be in the cases. Understanding this can save your eyes or teeth!

Yes...that is the point I was making to the person that posted that...he would not have had to pull his bullets to find out what his problem was and would have to have driven the bullet out of the barrel.

Grinding a die down removes the radius at the entrance.

Redding makes shell holders that push the case further into the die. The set includes six shell holders: 0, +.002", +.004", +.006", +.008", and +.010".

Yes, but since the case is tapered it does not care whether there is radius there or not, as best I can tell. But it is easy enough to hit it with a Dremel and create a taper, if you want.

I love the RCBS dies, and do not want to switch anything out.

I know you got it, and my post was not directed at you, other than to reinforce your point. I should have made that clear.

 

[Tokay444]

If the results are the same, I'll always choose to modify a $4 shell holder over an $80+ die.

False.
