Re: Which die should I use?

Do you need a lubricant on the body die and if so will the Imperial Sizing wax work?

    Samson & Desert Fox,

    The belt prevents ANY conventional resizing die from reducing the "pressure ring" on ANY belted magnum case. The pressure ring exists on all rifle calibers. However, the pressure ring creates a unique problem for belted calibers causing handloads to stick in the chamber. My website describes this subject in great detail, and it shows yo how to solve the problem. Check it out and, you'll see why the U.S. Secret Service (and 1,900 other shooters) are using our Belted Magnum Collet Resizing Die.

    Just curious. Why is the Forster Seating Dies better than the Redding Competition Seating Die?

    I am ready to buy the Redding Competition Die but I may have to rethink this.

    [/ QUOTE ]I don't think it's the case belt but instead the full-length sizing die's design. These dies have a rather large radius at their belt clearance to body sizing chamber. It's large enough that the body sizing part of the die can't size all the way to the belt. Belts on cases rarely if ever touch any part of the die during full-length sizing and rarely get reduced in diameter.

    But your die is a boon to belted case reloaders. It was in the early 1960's that top 1000-yard highpower shooters learned that new belted cases shot more accurate than any resized ones; neck, partial or full-length sized ones just didn't do as well. Careful measurements and observations proved that belted cartridge chambers made to minimum SAAMI specs had interference between the pressure ring on resized belted cases and the chamber where the belt headspaced. It varied across all cases and accuracy was reduced. Someone figured out that if the fired case body could be resized all the way to the belt eliminating the pressure ring bulge, accuracy would equal what new cases produced.

    A regular full-length sizing die had about 1/4th inch of its bottom cut off as well as its top just below the shoulder. The inside edge of the bottom was radiused just a bit, perhaps only a few thousandths of an inch, so it wouldn't scrape off brass when sizing a fired case until the die's bottom just touched the case belt. Sometimes more of the die bottom would be cut off so case diameter just in front of the belt was the same as a new case. I've used dies like this to size belted cases a second time after running them through a conventional full-length sizing die to set the shoulder back several thousandths first.

    Many folks made their own body sizing dies this way as nobody had one commercially available until yours was put on the market. The process does work very well. Any conventional full-length sizing die can have its ends cut off and used for different cartridges with the same body taper and new case diameter in front of the headspacing belt. The advantage of your die is it's collet adjusts how much the case body gets reduced.

    When you guys talk about "bumping" the shoulder back, what does this mean and how do you do this?
