I have used a ton of them with no problems whatsoever. However there are some that say they have trouble with them in cold weather. I guess it's not cold enough down here in South Georgia for it to be a problem. Jackie B.
I shoot them, exclusively - and have for a few years now. I have NEVER experienced any types of problems, either in fit or consistency of ignition. Living in PA, I shoot in all "four seasons" - temperatures ranging from teens to nineties.
I would not hesitate to recommend Fiocchi primers to anyone........
I have used over 30,000. No problems with alliant powders. I shot yesterday in 11 degrees and no problems. I will never buy Win or Rem primers again to their prices get more in line. Fiocchi primers are 1/3 the cost and work just as well. I even use the in the .410. Mike
Some shooters blame the primer, it's not the primer in cold weather nor the powder, it's the wad, fiocchi and cheddites are fine even in subzero weather, not so with the wads, problems? look to the wads! incinerate em!
Bought about 7,000 of these and used approx. 1,000 with Red Dot & Green Dot powders, wads were Versalite or Figure 8 Remington. No problems thus far. People have told me that Fiocchi primers a slightly larger and once you have seated one in your case then don't switch back, say to a Winchester primer. I've shot these in temps less than 10 degrees last 2 weeks with no problems. Does anyone know whether these primers are larger in diameter? My next trip to the basement, I'll mic a few to find out whether it's true or not. So far I would recommend use of Fiocchi's. Darrell
I've had off sounding loads in colder weather using the Fiocchi 616 in certain loads. The worst appeared to be with Red Dot or Promo powder. Several different wads were tried, including the Originals and quality clones. The problem was there with all. Changing the primer cured the problem, so I doubt it was a wad issue. The only real wad issue I had was with the Dusters a few years back. The over powder cups were fracturing, due to some poor quality plastic they were using. Recovered wads from the off sounding loads with Fiocchi primers looked normal without any breakage.
Note, there were no misfires and the variations over a chronograph showed lower velocities for the off sounding loads. They were still fast enough to reach out and break a target, but the sound was not right. I generally use Winchester or Federal primers in the cold. The Rios have worked well also, but data is limited and they seem to raise pressures dramatically in some loads if you look at the available data.
