How many of you actually use a factory crimp die? I don't but some have warned that shooting a semi-auto may push the bullet in enough to cause unsafe pressures.

Not 100% sure, but don't think the crimp die will change the pressure unless your crimp is also reseating the bullet.

I believe he is concerned about bullet set-back during firing which will raise pressure.

I use the LFCD on every round that I load. If you are talking about semi-auto pistol, I have learned that you only want to set the die to push the flair back in and not to actually crimp. The neck tension should be enough to hold bullet in place without any set-back.

For semi-auto rifle, you want to apply about a medium crimp to avoid possible set-back issues in those rounds.

Do ranges allow you to use Chronographs? I been thinking of getting one but would be kind of useless if not allowed. Thanks!

Outdoor ranges typically yes during the cease fire you set it up. Indoor ranges typically no. If you get an expensive lab radar one probably it would work anywhere.

Glad I subscribed to this thread. The learning never ends.

Okay, cool. I was thinking of something like this one.

I use all 5 stations on my Lee .
I crimp mainly semi auto pistol , but also do the 30 M 1 carbine and 270 W .
I set my crimp so there is no flare on case . By that I mean I run my finger over where shell meets cartridge . A slight step down from case .
On the rifle cases - kind of a like a dent .
Do the check with factory ammo and see what it feels like .
Crimping is like salt - everyone like a different amount .

I actually HAVE the crimp die. The problem is that I am using a single stage Lee Handpress (if you have a bench mounted single stage press it doesn't actua;y change nature of the problem). I actually have two of those Handpresses. I have the resizing die on one, the seating die on another. I generally don't unscrew the dies unless I am changing calibers. I am actually thinking about buying additional presses so I can have one press for every die I own; they are dirt cheap.

My concern is two fold... one being that during chambering it is not uncommon for the nose to slam against the ramp on the wat into the chamber. The crimp prevents the bullet from being pushed in during the chambering event. Another thing (albeit less of a concern with practice pistol ammo than with precision rifle ammo) is that neck tension very slightly increases resistance to the bullet moving forward during the initial phase of igniting the cartridge. More resistance = more chamber pressure. More importantly, consistent resistance = consistent initial chamber pressure and hence lower velocity spreads.

This is one of the reasons I use all 5 stations . Not a big believer in 2 or 3 die set ups .
Same with priming on a press - deprime , clean [ kind of inspect ] reprime and finger test depth .
Seating , OAL and crimping all at once - no thank you .

Looking good!

Thanks!

For those interested. Sportsman Warehouse recently opened up in Fairfield. They have quite a bit of reloading gear including reloaded, wet/dry tumblers and dies. Not the best prices but at least no shipping or hazmat fees. For me its across the highway.

Whoooo hooo!!!

Anyone know where in the greater Bay Area to go buy reloading components? Other than that Sportsman Warehouse post up there.
