this is a long range site and as far as i know "crimping" does not fit anywhere in that picture.
if pistols or ar's maybe ask there.

2 similar posts---some people swear by lee fcd, some don't-its an long time debate, as with any "to crimp or not to crimp" debate---it's a preference thing that will probably never be answered except by the guy doing the actual reloading

not sure about ar10man, but I have--- in some cartridges it seems to help, some it doesn't-- also can be different for each bullet in same rifle--I have seen small changes for the good, and small changes for the worse--but never seen a drastic change- yet
I usually develop with out a crimp, then when I get my load refined I will sometimes do a crimp/vs no crimp test to see if I can improve any more

the real problem is NO SPECIFICS listed...
so you cannot answer the question with specifics.

are we all shooting bench rest guns in competitions?
this is a classic "to crimp or not to crimp" thread--they usually end up in pi__ing matches with people repeating things they have heard on the internet with no real proof
like I said, some times it helps, some times it doesn't the best thing to do is try it for your self to see if it works
if the OP wants to see a real test-- here is a report that someone did for them selves
http://www.accuratereloading.com/crimping.html
does it prove it will work in every gun? no
does it prove it will work for you? no
does it prove it worked for him? -- depends on how you extrapolate the data
does it hurt to try it to see if it helps for you? probably not
isn't finding that "perfect load" all about trial and error? finding about what improves the grouping and what doesn't? isn't that the core of hand-loading?
as you can see by this article, not every one does the same thing when reloading for matches https://precisionrifleblog.com/2015/12/31/reloading-tips-from-top-precision-rifle-shooters/ and this one https://precisionrifleblog.com/2015/12/27/best-bullets-brass-primers-powder/ (I know, not bench rest, but it is PRS) -- find a guy that shoots as a profession and ask him all his secrets, see if he will tell you

The point is we are both striving for the same goal. That is ultimate accuracy. You're on a long range hunting forum. If you're not after ultimate accuracy you have zero business shooting game long range period. If we can't agree on that we have nothing left to say to each other. Almost everything we use in long range hunting has roots in some form of competition shooting. Back to the point that is really a fact crimping is not conducive to ultimate accuracy. I can lead a horse to water but can't make it drink. Good luck.

I've tried a Lee crimp die for my .338-06 with consistent results concerning SD/ES. I've also had consistent results concerning SD/ES NOT using the crimp die. Made no difference, so I decided to not include the use of the crimp die in the reloading regimen for that cartridge.
Rephrased question to be more specific. I am not interested in hear say o on knowledge gained from first hand testing. The second aspect of questions is about tuning loads. My extreme spreads are touching on 20 I would like to cut that in half Most of my shooting is at1000 to 1200 yards
