Do you crimp your 30.06 loads

Just started loading. This is my first batch actually. Do you guys crimp your 30.06 loads with the Lee Die Factory Crimp?

Thanks

Don't crimp.
Don't use Lee dies.

Call BS. I've been using Lee for my 30-06 forever. Even load 130grn varmint loads. Furthermore, many many loads benefit from a crimp. If you run them through a crimp die, they even work in semi auto rifles. You'll never eject a live round and leave the bullet behind still in the bore. No crimp might as in maybe be alright with single loaded rounds. Bench rest guys load single rounds for single shots, but most of us will profit from a crimp.

Nope. I only reload for bolt-action rifles so there's no need for crimping. As for semi-auto, crimping is recommended.

Nope, I agree with Rifleman1776, crimp only if used in a tubular magazine. Further, if a projectile doesn't have a cannelure don't crimp because you may distort the bullet. Sierra took Lee to task a few years ago and subsequently Lee retracted there crimp for accuracy campaign especially if there isn't a cannelure. With that said I do have Lee crimp dies for a couple of rifles, it's important to know when it's O.K. to use a crimp! There can be a case made for heavy recoiling calibers to crimp if a cannelure is present, without a cannelure I would not crimp.. William

I use Lee dies, and I set the seating die to just start to crimp.

Crimp for ammunition for use in semiautomatic rifles--M1 Garand as an example.

Don't crimp for ammo used in bolt action rifles.

Not even there.
(Match 168's and 175s used in M1s & M1As' don't even have crimping grooves)

Crimping is neither required nor even desired for most North American-rated cartidges and normal bullet shank seating depths.
(Note: I do crimp the likes of heavy 375H&H and my 458WinMag, and those bullets do have crimping cannelures)

I don't crimp for either bolt-action or for my M1, but I do use Lee dies (just not the factory crimp die).

bullet crimp: I am the fan of bullet hold, I want all the bullet hold I can get. Neck tension? I can not measure neck tension.



Crimping bottle neck cases, the bottle neck case must be trimmed to the same length when crimping, When crimping bottle neck cases that are not the same length problems are created when the shoulder of the case collapse and or bulges.

Thank you all very much for your replies. I tried as hard as I could to pull out the bullets with my fingers without success. That was good news and I'm leaning towards not using the Lee Factory Crimp Die. Just wanted to validate my thoughts with you seasoned reloaders.

Thanks

PS

It is for a bolt action.

Some of us are more "seasoned" that others.
(But at least we all have strong opinions.)

I have Lee Factory Crimp Dies for all six calibers, the only time I use a crimp is when I can't get a load to shot good, less than MOA. For the most part I don't use them. The best part about handloading, is you get to go shooting and when you find a load that works there is a good deal of satisfaction. Work up two identical loads one without a crimp one with a crimp. You'll probally come to the same conclusion as most everybody else, no crimp necessary on a bolt gun. So if you buy the crimp die and doesn't work out you're only out 12 bucks and you will have the piece of mind knowing it is not necessary in most cases.

I put a 'slight', emphasis on 'slight',,, crimp on all my handloads. It's barely noticable with mics. It doesn't matter to me if the bullet has a cannelure or not. Consistency is the goal & that way they're all the same. M1 Garand, 1903 bolt action, semi-auto AR's, whatever.
I don't shoot match so the only time I load one round is when I'm doing load development & I'll still crimp,,,,'slightly'. My ammo isn't handled with kid gloves. Ammo gets bounced around in the truck, ect. I've never had bullet set-back or extension. Just my opinion but crimping works for me.

Use Lee dies without any issue. Never crimp.

If you have an inertia (hammer type) bullet puller- make up a dummy ctg and see just what it takes to coerce that bullet out of there. The first time I had to use one of those... it was certainly an eye opener. I thought I was going to beat my work bench to death.

I've never crimped a bottleneck rifle ctg.

I dont crimp for bolt action or single shot handloads but I do crimp with a Lee FCD for my .223 handloads. I put a ever so slight crimp. Very light, I guess for piece of mind more than anything else. It also puts even neck tension on my rounds which aids in accuracy IMHO.

I use some Lee Dies they are OK for low volume loading jobs. Back 20 years ago the factory crimp dies were in style for awhile. It did not take shooters long to figure out the Lee Crimp Dies was not an aid to accurate loads. I never crimp for M1s never had a problem.

I don't crimp for any of our bolts or semi's...
IMO, it just adds another variable that can increase pressures, and I don't see the need for it.

With semi's, some crimp because they are concerned about bullet travel in the case either while being chambered, or bounced around in the field.

Haven't noted an issue with the former, and since I'm not deployed military, the ammo/clips don't get abused so no concern for the latter.

Ya know, to crimp, light crimp, or not to crimp it seems to be a matter of opinion. Form you own opinion, do what works best for you/your gun. What else needs to be said?

sometimes Ill put uncrimped rounds in the mag and run them through the action, almost all the time the neck tension will be enough to hold the col when I remeasure them. I'm just saying most of the time it seems like a crimp is not needed. but then again factory ammo is always crimped....tubular mags are a diff matter. I also like to crimp my revolver magnum rounds, just to be safe.
