Lord Geordie Posted April 13, 2013 Report Share Posted April 13, 2013 The normal cause of hexagonal cartridge ends is that the first crimp is too deep ,crimping the area where the rim will be folded along with a too deep center and not enough taper crimp if you adjust correctly you can get a factory finish try Hull Soverings or Pro 1 cases Deershooter I know it's the pre cutting too deep, I meant your finished crimp can be hexagonal. I touched on this on another post to a member having trouble. I explained the benefit of not bringing down the pre crimp all the way. I also mentioned the 1 euro cent being the perfect size for more final crimp depth! Some people have trouble with reloaded hulls cycling in auto's and I am sure thats perhaps the sole reason many use the spinner! Quote Link to comment Share on other sites More sharing options...
Lord Geordie Posted April 13, 2013 Report Share Posted April 13, 2013 I understand why they use the RTO too, but my point is its not necessary if you have your machine set up properly, and if your cases are in good enough condition and you have the wad column correct. And if you do use a lee load all the addition of a small washer will do a job of forming a good crimp for nothing. And at 40 quid or 30 quid for a brass GAEP you are half way to buying a second hand Mec that you can adjust to get decent crimps and tapers with no RTO needed. If you need a RTO for your loading fine, but using one to tidy crimps up is ridiculous and potentially dangerous i think using one could raise pressures considerably far more than adding a washer to a lee ever could. You leave my Wad column out of it All of my loads are set with the correct wad height even the few that needed that little adjustment with a bit of packing. My crimps tend to be spot on! It is more the people who end up with 20p symdrome on their reloaded hulls that resort to the spinner. I have seen people trying to load carts that have bulged and some where they tried using a 36g wad and 28g of shot and the crimp is just a big hole in the end The funniest was a chap who hadn't resized the brass and the cart's wouldn't go in the chamber He ran a batch of 200 Quote Link to comment Share on other sites More sharing options...
deershooter Posted April 13, 2013 Report Share Posted April 13, 2013 I do use 36 gram wads in 28gram loads !!!! The B&P Z 21 is normally used in 36 gram 70mm cases however I use a Z 21 in a 67 mmm case with 28 grams of shot Deershoter Quote Link to comment Share on other sites More sharing options...
Lord Geordie Posted April 13, 2013 Report Share Posted April 13, 2013 (edited) I do use 36 gram wads in 28gram loads !!!! The B&P Z 21 is normally used in 36 gram 70mm cases however I use a Z 21 in a 67 mmm case with 28 grams of shot Deershoter yeah but the Loadall is set up for.70mm hulls What I was trying to point out is some people just use ANY component and think it will make a useable cartridge. I find one of the 24g wad better than some of the wads i have for 28g in the 70mm cases. It.brings the stack height slightly further up where the 28g ones were a tad short leading to a concave crimp.

That's what I've been using anyway. Quote Link to comment Share on other sites More sharing options...
