I was told not to put a crimp when reloading brass cases, and I haven't been doing that.

So now to the actual question.......would it hurt anything if I put just enough crimp to hold the bullets?
It would help if you included what cartridge you are reloading and for what rifle. Personally I crimp all cartridges for the every reason that you mention. I have never had any problems with overpressure. Make sure you crimp on the cannelure as that is its purpose. I use the Lee Factory Crimp die for rifle loads and have found it to be the best out there. On pistol loads I use a roll crimp.

(edit) As to not crimping, your COL will increase and can cause the bullet to contact the rifling when chambered, this is a big no-no on jacketed bullets! (again from the Speer manual).

Best advice is to read what your reloading manual says and stick with it. Any time I get some advice from another reloader I will cross-check it with a manual before trying it myself, sometimes the advice is strictly not recommended in some manuals.

In my Speer #13 manual on page 79, Step Nine is all on crimping. In short, it is optional and they say that it is "not needed for every cartridge or firearm", but that cartridges to be crimped "must have a crimping groove". It also says that crimping is recommended for (in part) "Ammunition for rifles with tubular magazines, semi-automatic rifles, or heavy recoiling rifles with a magazine."

So check your manual!

By the way, there is a whole section on reloading here on FTF and it would be totally appropriate to start a new thread there with any of your reloading questions.

Very good answer. Have had a little lightweight .350 magnum that you damned well BETTER crimp- or the third round would be case, powder, and bullet waving to each other. As they went their separate ways.

Thanks Viking, I'll be sure to head on over to the reloading section and toss up a new thread. I'll put the information I missed (caliber/rifle) in there as well.

Don't know of any places but you can't go wrong with a cheese steak and a beer.
