Should I crimp a jacketed projectile?

The 405 gr Remington bullets are jacketed.

They are:

Probably because it puts less fouling in the bore and can stand higher tempuratures/pressures of lead bullets. Smile

Thanks Dimitri ........... that sure enough looks like em........ Smile

I crimp ahead of the last cannelure. You see the line closer to the top of the bullet? Well that's where the bullet begins to taper and that's where I seat it to and then crimp. Cool

I would think a roll crimp would be better on lead or are you using jacketed bullets. The Lee FCD tends to loosen the grip that the case has naturally if the bullet does not have a cannelure, I would think. Could be wrong. Have been before. Will be again. But not often...

Bushy old mate...I could never in a lifetime imagine you being wrong....mistaken on the odd occasion but not wrong.

I use the Lee FCD on both types of bullets and have noticed no difference. In fact I am going to get one for crimping 30.30 instead of using the roll crimp on my die. This is the blurb that Lee putt out on the FCD:

Guessed that you all knew about the camel's hump...just felt like showing I knew too. Laughing

OUCH !!! But I have lost a bit of weight. Give it another 2 or 3 years and I will be a shadow of my former self. Very Happy

Yup...I've been using a Lee FCD on my .30-30 rounds for a number of years with great satisfaction. It has eliminated two problems...I no longer have to worry about crushed shoulders when seating and crimping (crimping is a seperate step with the FCD) and accurcy has improved...

When I bought my 45-70 some years ago I ordered my Lee reloading dies and the Lee FCD right from Lee Percision's web site. The FCD works excellent and for the price, $12 or $15 they charge for it, it's a steal. I wouldn't crimp any cartridges without one. Smile
