snow white Posted January 13, 2016 Report Share Posted January 13, 2016 Hi I am reloading 17 hornet the primers on some of the cases at not sitting right they are sticking proud about 3/4 mm.tried reamering the hole but it would take to much brass out I think to be safe.tried different primers still the same.besides throwing the cases away help would be very grateful.

Redgum Posted January 13, 2016 Report Share Posted January 13, 2016 I reload .22 hornet wit no problem, can't see why the primer pockets would not be deep enough, not sure what priming tool your using but are you sure that's not the problem and they are not just being pushed in far enough.

rem708 Posted January 13, 2016 Report Share Posted January 13, 2016 have you measured the depth of the primer pocket. I've never heard of this and find it rather odd as they have obviously had primers in before. Are you actually seating them fully? What make brass?

snow white Posted January 13, 2016 Author Report Share Posted January 13, 2016 (edited) Hi I load 223 never had trouble with them.the primer pocket is not deep enough on some of cases the depth is 3.20 on the bad one's its 2.40.I brought these as once fired their are 34 of them don't really want to throw the away but it looks like will have to.tried hand loader and the one on the press when I put the pocket reamer in you can see where the brass as rubbed on it will try to get photo to put on.

Redgum Posted January 13, 2016 Report Share Posted January 13, 2016 If they will not seat the primers and the pockets are not deep enough chuck em, doupt if they are once fired, and if they are they must have been hellish hot, is the writing on the case bottom still readable. If it is still real clear then it must be a case irregularity and factory primer seating whacked em in until they fitted. But still, chuck em.

shooterman49 Posted January 13, 2016 Report Share Posted January 13, 2016 i have had the same problem with trying to reload my 17 hornet cases. I was using once fired hornady cases and experienced the same as you with some primers not being seated properly. talking to my local gunshop he suggested using match primers as they should be more consistant. have purchased some and have not got round to trying them yet. will let you know how I get on. regards pete.

snow white Posted January 13, 2016 Author Report Share Posted January 13, 2016 Shooterman49.thanks for that thought it was me doing something wrong.where did you get the primers from if you don't mind me asking don't really want to throw all that brass away as you know they are like rocking horse **** to find.thanks Tony Quote Link to comment Share on other sites More sharing options...
Dougy Posted January 13, 2016 Report Share Posted January 13, 2016 Can't see br primers being any different depth wise. As mentioned measure the depth of the primer pocket. What are the primers like that came out ? How much pressure are you using to seat them? They can take a bit of pushing as long as it's square and even.

Albert 888 Posted January 13, 2016 Report Share Posted January 13, 2016 What brass are you using. I had loads of bother seating primers into once fired in my rifle hornady brass (308). It was shearing crescent shapes of the primer. They all shot,but I binned it after I fired it. Quote Link to comment Share on other sites More sharing options...
Redgum Posted January 13, 2016 Report Share Posted January 13, 2016 Why would they be "hellishly hot"? As in an over pressure issue from a hot load, just an idea. I have never had a primer depth issue in larger calibres and have only just started reloading Hornet( as in just into my second hundred). The Hornet is quite a fragile case and would over pressure possibly cause lower case compression or flow. Quote Link to comment Share on other sites More sharing options...

I am trying to understand your thinking.Why would a shallow primer pocket cause "over pressure"? What is over pressure? Pressure on top of something, is there under pressure (like me at work) and where is middle pressure? Is it in the middle or off centre a touch?

Pressure is trying to explain something to numpties on here Not why would a shallow primer cause over pressure, but possibly a case loaded with too much or two fast a burning powder, you still with me to this point underdog, may cause a dangerous amounts of pressure for this case. Now you may not have come across flatten primers or base of cases get compressed enough to flatten out the writing but on a weak case like a hornets would it be possible to flatten the base. Then when a new primer of correct size is inserted it stands proud as primer pocket has lost depth. Don't get too stressed about it mate, it was just an idea of how a primer pocket could possibly end up to shallow.

Redgum Posted January 14, 2016 Report Share Posted January 14, 2016 I have a case in front of me now and I think it would be possible to compress the case enough to show a primer sticking out 3/4 of a mm, you probably would have to use something faster burning than lilgun as the case capacity would make it difficult to get enough powder in to cause that much pressure. There is only one way to find out, track down the guy that sold the ' once fired cases' tie him to a chair and attached his gonads to a 24volt battery 007 style, the truth may possibly reveal itself. ( bet they were ppu cases) Quote Link to comment Share on other sites More sharing options...

Oh right, for some reason I thought you had bought the cases as once fired, are they new cases or once fired in your rifle. what make are they Edited January 14, 2016 by Redgum Quote Link to comment Share on other sites More sharing options...

Got ya, hmm the only excessive pressures I experienced in Hornet was while messin' with blue dot.It and also experienced in other cartridges, would blow the primer pocket, making it impossible to hold a fresh primer. I never experienced the pocket becoming shallow. Quote Link to comment Share on other sites More sharing options...

Me neither, does sound a bit strange and without knowing the full facts its impossible to solve a mystery like this, were the cases damaged after first firing, if so then snow white would have not managed to seat the primers correctly the first time he reloaded the cases, or did he, or was it one of the seven dwarfs. Like yourself I have had loose primer pockets, flattened primers etc, the usual signs of pressure that are listed in reloading manuals. Best get some new cases, if they won't seat then they won't seat. Quote Link to comment Share on other sites More sharing options...
activeviii Posted January 14, 2016 Report Share Posted January 14, 2016 Hornady cases for you. Hate them will not use them. To thin and to random. 6.5 creedmoor cases are either hornady of very expensive noslar. I make my own from better quality companies. Getting back to your issue. Ream the pocket down to the correct depth or you could switch to pistol primers as they are shallower. What primers are you using. Hornady cases for you. Hate them will not use them.

mick miller Posted January 15, 2016 Report Share Posted January 15, 2016 Try the fiocchi primers Fister recommended or look online for alternative (of you Google 17 hornet primer) there are a few mentioned. My plan is to get Fiocchi primers but I've yet to find a source for these and Fiocchi's own website makes no mention of them. Quote Link to comment Share on other sites More sharing options...
snow white Posted January 15, 2016 Author Report Share Posted January 15, 2016 Just to keep you all up dated my mate come over with a box of empty brass that he shot of I resized some and the primers fitted perfectly. They were factory rounds so these where first time shot will make a couple up try Sunday on the range. Quote Link to comment Share on other sites More sharing options...
mick miller Posted January 15, 2016 Report Share Posted January 15, 2016 Good luck and thank you Chris for the pointer for Kranks. I'm lucky enough to have a pretty good reloading store nearby, but they don't stock everything. Quote Link to comment Share on other sites More sharing options...
