WNCRob.... I have been using Fiocchi primers for some time now. I can reload a Winchester 209 back into the primer pocket that had a Fiocchi in it and have had absolutely ZERO problems doing so. Load the Fiocchi's and don't give it a second thought. Great primers at a great price.... Dan Thome (Trap2)
I believe that years ago the fio's were slightly larger (say mid to late 80's. That is no longer the case. They are slightly different - the primer body is straight, where the win/rem primers have a slight taper. I think the fios are about 0.005 larger at the flash hole end, and about the same or slightly smaller at the flange end. About all this means is that they are a little harder to seat, especially in Remington hulls - the first time.
Fiocchi's being over-sized is an old urban legend that USED to be true when these primers first came out as a replacement (Fiocchi 615 if I remember correctly) from the original Alcan 220 "Max-Fire" primers which WERE oversized. I'm loading the new, current Fiocchi's (616), and haven't noticed any "stretched" pockets or loose primers when decapping and reloading another brand of primer back into the same hulls. ....Rick
The Fiocchi's I have in my hand measure 2 ~ 3 thousandths more than my Feds and Wolfs. When I use them in GC or any other steel-based hulls, they WILL make other primers fit more loose, and I will get leakage from these. Say what you want, but the micrometer doesn't lie!
Andy44 is right; I found these primers to be approx. .003" larger when measured just under the flair of the primer cup vs say a Winchester primer. Once you start using Fiocchi's then don't switch to another primer. Personally, I have good results with these primers and would recommend the purchase. Darrell
Sorry boys, but the last 3 or 4 responders know what they are talking about! I have measured several from 3 different bricks/lot numbers and they are .0025-.003 " larger in diameter than my Fed 209As. If you do not believe this, just for the fun of it, insert a few into Fed Top Gun hulls and then deprime! I guarantee you will then be able to push Fed 209s in with your thumb and get them out with your fingernail! Sorry if I offended any of the "urban legend" boys! Tom Rhoads
Fiocchis are a uniform dimension from front to back. Other primers taper slightly from front to back.....hence the inside of the shell will be enlarged by a few thousands. Might not be a problem in most guns.
I have miked several hundred primers (100 each), F 616, win 209, Cheddite, and Remington 209. The largest primer miked was a win 209, by 0.004". They all were miked as near to the flange as possible. Bob K
Well, this is good stuff! I wonder if all primers vary somewhat in diameter by as much as 2 or 3 thousandths...that's not much, but it can make a difference I guess. I'll bet that much variation is deemed acceptable by the manufacturers. It would be interesting to find out what their design/manufacturing spec diameter is. Think I'll contact Fiocchi and see what they have to say. Actually, I've heard very good things about the consistency of 616's ignition properties.
Say what you want, but I gave up on the cost savings realized by loading Fiocchi primers. Went back to Winchster's despite the increase in cost. The Fiochhi's DO have ignition problems (but never during a practice round) and DO measure a bit larger. The larger size didn't bother me, but the "CLICK vs. BANG" got very old. I finally gave away the remaining Fiocchi's I had left. Final answer.
I'm just finishing up my third sleeve of Fiocci's. I've never had a misfire or any problem other than my supplier not being able to get them for a while. I use them in old style AA cases with 18gr Red Dot, 1 1/8- 7 1/2 shot and Claybuster AA wads, 1182fps on a chronograph. Summer and winter with no off sounding loads. Try them You will be happy with them.
