.270 Gibbs

  1. Q#1. I want to know where to get some dies for a .270Gibbs based on the .270Win case length if you can?
  2. Q#2. I want to know how you are fire forming the brass expanding it up to say .30 cal or 7mm and then running it thrugh a full length .270 gibbs die?

    Nape.270,

    The dies for the .270 Gibbs can be ordered from RCBS, Redding, or Hornady, but they are strictly a custom offering, meaning that they are not stocked and have to be made on a order only basis.

    I know that the die makers are behind due to the increased demand that they are experiencing right now (12-16 weeks). I would contact Lonnie Hummel at Hornady, his E-mail is custom@hornady.com or call him at 1-800-338-3220 ext. 208

    They will need 3 fired cases or a chamber reamer print to make the dies. They use EDM machineing and make the dies to fit the chamber of your rifle. If you haven't built the rifle yet, Pacific tool and gauge can send you a reamer print if they have it on file that Hornady can use to make the dies while the rifle is being made.

    I'm not sure about RCBS or Redding but they may have the die reamers already on hand.

    You are right about having to size up the brass to fire form a Gibbs. The Gibbs has a sharp shoulder an shorter neck than a "Ackley Improved" case with the shoulder being pushed forward. The resizing of the neck (running it through the Gibbs die), after having been "necked up" creates a false shoulder that the case can head space off of. You then Load this case seating the bullet into the lands. Using a mild Powder charge (a couple of grains off of max of a .270 Win load) you fire form to fit the chamber. You may have to do this twice if the cases don't fully blow out, but that's not usually the case. It's a similar method to forming the JDJ cases.

    Hope this help

    Re: .270 Gibbs

    Thanks for the help.

    I was wondering what kinda of velocity the 130gr and 150gr bullets are going out at. I read in the P.O. Ackley Volume II that the 130gr go 3400fps and the 150gr's are 3200fps not sure what length barrel. mine will probaly finish at 28 inche's.

    Nape,

    Looking at the Ackley Improved numbers there is a substantial increase in velocity and case capacity increase. The Gibbs version has even more case capacity increase. While I don't have the exact numbers, Quick Load can esitmate what the velocity increase would be.

    Alot would depend on sutable powder choices. H4831SC, IMR7828SC, H1000, RL22, and H4350 are all good powders to start with. H4831 and RL-22 are excellent in the parent case, so they would be a good place to start. Highest velocitys should be with RL-22.

    I think a 28" bbl would serve this round nicely to get a high rate of burn with a slower powder.

    Cool,

    I don't have that book, I was looking as data that I've been able to round up on the Ackley version. Still those are very excellent velocitys for the Gibbs version. 3400fps for a 130g bullet is smoking! and 3200fps for a 150g bullet is excellent. I'm interested to see what you can squeeze out of the Gibbs. It should be quite a shooter.

    Ps. Reloader's nest has some data for the .270 Gibbs, here is the link:

    Just saw your post..

    Don't know if you found dies, if not call Sid Goodling in Stoverstown, Pa. he has them sitting on the shelf. He has all the Gibbs reamers too.
