I have decided to start reloading for my 300 WSM Browning Stainless Steel Stalker. Price of factory ammo is getting a little stiff.

I have a question about crimping the bullet. I have read that if your going to use a bullet for hunting, it should be crimped, rather than just seated into the neck of the case. Now most bullets that I have been looking at do not have a groove in them, and in order to crimp them they must have this "groove". Or so it is written.....

When I look at the various factory loads (Winchester Power points, Federal Fusion, Remington Coreloks, etc) I don't see a "crimp" per say, it just looks like the bullet is simply pressed into the case.

Do I really need to worry about crimping the bullet into the case if I'm planning to hunt with it? If I have to, how in the world to I crimp bullets that have no groove manufactured in them for crimping?

Kindest Regards,

Highly disagree. I do not crimp any of my rifle ammo. Even when I shot 300RUM. I have tried it with mixed results.

Oops, I do crimp my 45-70. You will find most if not 90% do not crimp rifle ammo. Keep it to pistol's and straighwalled rifle calibers.

Unless you are in the habit of dropping your ammo on the ground a lot, or are shooting 400+ gr bullets out of the dangerous game rifle, crimping isn'tnecessary in a bolt action.

If you feel the need to crimp your loads use the Lee Factory Crimp Die. It will work with any bullet "groove" or not.

Many reloaders use the Lee Factory Crimp and claim increased accuracy. Give one a try, they only cost $8. Here is some interesting reading on the LFCD.

The only time I crimp is for lever guns with a tubular magazine, otherwise no crimp. It's up to you though.

I was thinking the same thing when reading through this post. In a tube fed levergun you are pushing one bullet into the other to "force" it into the tube. I have had 30/30 reloads without a crimp push the bullet into the case further thus increasing the pressure of the give round. Not only that, but accuracy is diminished from round to round as a result. So yes, for levergun ammo, I would advise crimping but for magazine ammo I wouldnt think that it is neccessary.

THe SPeer #13 manual has a pretty good section on what to crimp or not. Give it a read if you get the chance. I dont crimp and of my rifle rounds either.

Crimping is not necessary in most rifles, but is advisable in a few as discussed above. If the bullet does not have a cannelure or crimping groove then the best advice is to use a taper crimp instead of a roll crimp. Just simply buy a taper crimp die. However be careful. Crimping can adversly affect chamber pressure. Work up to a crimp the same way you work up to a max. load. Tom.

the only rifle cartridges I crimp are my straight walled calibers and anything that I plan to use in a tube magazine rifle and semi autos.

I think a better way to state that would be "work up a load based on crimp pressure"
