Crimping Die for 340 Weatherby Mag

Does any one know who makes the best crimping die for a 340 Weatherby Mag. Also, where can buy one?

Most Seating Dies have a Crimp section built into them. What kind of Dies do you have that does not include the Crimp?

Forester dies, I did talk to Lee today and they said that they would build me a custom crimp die for it.

Are you sure a crimp is needed? Have you seen bullet "creep" in your handloads?

Lee built a Factory Crimp Die for my .340 for about $25 plus shipping as I recall. I sent a dummy and it took them a couple weeks.

Does it matter the COAL of the bullet. Do I need to measure the rifle to get the correct length to the rifleing.

My personal opinion I think I do want a crimp, reason being if I am on a dangerous game hunt I want to have the confidence that my bullet will always chamber. You never know if that bullet will creep with the recoil of your higher caliber rifle.

I did not realize Forster Dies came without a Crimp feature.

I know for sure RCBS and Redding include a Crimp feature in their Seating Die. Also understand why you are wanting to Crimp - so would I. I'd be less concerned about locating the best possible Seating Depth Length and more concerned about the Bullet moving in a Dangerous Game, up-close, situation too.

Do the Bullets you want to use have a Cannelure? If so, you could get either an RCBS or Redding Seater and be ready to go.

I know a lot of folks speak highly of the Lee Crimp Die, but I've never tried it. Many also mention of having to "modify it, clean up burrs, polish down the spindle, etc." to make it work the way it should from the beginning.

Best of luck to you.

No. In fact, no crimper is based on OAL, it's based on normal case length and Lee knows what that is.

Lee's Factory Crimp Dies are the best on the market, at any price, but it does have a moving part (the collet) and that seems to throw some people off course.
