All has to do with money I guess. Could sell primal and put extra on components but it would be more hassle I agree. For those who bought the primal early they probably could sell it for a profit right now.
Just saying those who bought a primal for 5-600 can sell it for $650 and buy a Hornady for $250 and put the rest on components.
Yeah, I'm pretty sure you are missing the point about repeatable primer crush with adjustable hard stop like CPS and a few others.
I'll say it again....yeah, its bench mounted, its square, it has a lever, and it seats primers.....THAT is the similarity.
lol . . . "crush" is a word that simply doesn't explain what one is trying to explain. It really is a poor word to use as some people will hear that and have a very exaggerated mental image of what that is.
The forum has a search function, ya know. Right there in the upper right corner.
"more accurate"??? Hmmm??? Are you confusing accuracy with precision?
Have you measured anvil legs/cups recently?
Call CCI, they will tell you .002 crush is recommended. It ensures the anvil is set against the primer compound for consistent ignition. It does improve SDs.
Revolver shooters in USPSA want to crush their primers.
Yes, sir...and another added benefit is that when you pre-sensitize the primer, it will ignite before the firing pin stops traveling (and disturbs the rifle 0.009")
If that's the case, then CCI has designed THEIR primers to be seated .002" below flush. But if that's the case, why don't they tell you that .002" below flush is recommended?
That's why the anvil protrudes out of the cup. This "per-sensitizing" (as you call it) is built into the primer at the factory.Yes, sir...and another added benefit is that when you pre-sensitize the primer, it will ignite before the firing pin stops traveling (and disturbs the rifle 0.009")
I like to prime my primers for all the reasons mentioned in this thread.
You do not understand what we are talking about. .002 below case head is not crush. Folks have provided video links on the subject, which you obviously have not looked at. Most brass manufacturers are anywhere from .003 to .005 below case head to accomplish a .002 crush. You have to measure the primer pocket and primer and do the math.
Not claiming to be an expert but I do know a little bit about primers. I would have no problem buying one of the adjustable primer seaters (cost not being an issue) if there was proof that they worked. But I haven't seen any such proof. And yes, I have shot 0s and1s.
You sound sure about even the manufacturing and design of primers, so I'll back out, as I am not worthy...and won't even bring up the 0.009" group the guy who "crushed" what would later become called the BR-4 primer.
Most benchrest guys crush my feel...hand primers...to the point where they feel the legs crush, then a little more...sorry you disagree with this approach, sir. I suspect you don't shoot 0s and 1s, though, given your disregard for ignition. Good luck with that.
That’s not what is referred to when talking about primer crush as has been explained to you in at least 5 posts above.
WTF… can you actually read. .002 of “crush” does NOT fucking mean .002” below flush.
Right. And here I was going to send him one of these to test, but he clearly has it all worked out—I mean, if you can shoot 0s using the firing pin to seat primers, God bless him. He clearly doesn't need any addition refinements.
Dang, learn something new everyday. Thanks!lol . . . "crush" is a word that simply doesn't explain what one is trying to explain. It really is a poor word to use as some people will hear that and have a very exaggerated mental image of what that is.
It's a little easier to understand if one says something like ".003 crush" or "006 crush" as it at least gives some idea of what one is trying to do. It really has to do with pushing the anvil into the cup and making its interaction with the primer compound more consistent when the firing pin strikes the primer. It's not about "crushing" the primer's cup itself, it's about the anvil.
And yes, primer manufacturers do recommend a "crush" when seating primers. Though I don't think they recommend how far as it'll depend on the various primer size (but I feel like I have heard they suggest .003"???).
And yes, benchrest shooters do "crush" their primers. . . AND, they're very particular about the strength of their firing pin spring and how consistent it stays for striking the primer.
I like to do .003 to .004" of "crush" when seating and have to do a little calculating how to get that by measuring the primer pockets depths and the height of the primers. That way when I measure how far below flush the primer is, I get a good idea how much "crush" I'm getting.
Precision shooting is ALL about consistency for everything involved.
Easy folks.
...and the variance between the primers in each respective box is just as prevalent.OK . . . so here some numbers that shows what kind of variations there can be:
CCI LRP cup height: .118"
Fed 210 cup height .117"
My CCI 200 primer height: .127"
My Fed 210 primer height: .129"
My Lapua LRP pocket depth: .130"
My ADG LRP pocket depth: .125"
My Peterson LRP pocket depth: .129"
My Starline LRP pocket depth: .121"
Go figure!
), but here's what SAAMI suggests is max seating depth below the case head.
Once you start loading on a 750 or 1100, you will never mess with that slow shit again. I couldnt imagine hand priming cases........
