Mike: I probably shouldn't respond to this, as I am surely not an expert. However, I am bored this afternoon; so I will give my $.02 worth. (It may not be worth that much). I reload and always load on the "low end" of the spectrum. Therefore I feel any primer will ignite my powder and the shot will be propelled to the target and break it. (Hopefully). However, it's when one "pushes the envelope" and produces a load that is on the high end of the reloading charts; that you need to be aware. So, if you load a very light 1 oz load as I do. Not to worry!! You can use most any primer. Cheddite, Fiocchi, whatever. The basic principal is that the primer ignites the powder. So, if you stick to the light loads as I do your OK. That being said, please consult the guidelines for the powder you are using. i.e., if using Red Dot consult the Alliant website, Clays, consult the Hogden website, etc. etc. Doing this along with weighing your powder drops on a scale will give you piece of mind. By the way, I use Fiocchi primers and am well satisfied. Ed
I have had some weak sounding loads with Red Dot and Fiocchi 616 primers but my Handicap loads with Green Dot seem OK. Cheddite primers did nasty things to the end of firing pins on my Browning Citori but that was over 5 years ago. I believe Cheddites are a tad hotter than Fiocchi primers. When my current 5k of Fiocchi's are used up I'm gonna buy something else maybe Cheddites again. I never had problems with Winchester primers in 45 years of reloading.
Just my personal preference, but two weeks ago, in the middle of a single-digit cold snap, I shot 100 26gm Cheddite reloads and 100 Nobel Sport reloads (in an auto). I noticed an unusually high number of poppers I don't get in warmer weather. That experience convinced me to save the off-brands for summer.
What was your load? Powder,wad & hull. Just interested because it was a topic of discussion today. Not much was said about the Nobel other then a good friend of mine ordered 5000 of them & asked me what I thought. I told him I guess you are in for a learning experience.....
Don't shot an "Auto" .....but I've never had anything CLOSE to a plopper with Fio's/Win's/Rem209's. I've shot in below zero many times too.I've shoot a few 25/25's with Unique and Fio's @ -0 . Perhaps powder is the issue?
According to Hodgen's web site reloading tables, the Fiocchi 616 primers are closer to the Federal primers and the Cheddite primers are close to the Winchester primers. the loads listed for Fiocchi primers just about duplicate the Federal loads and the Cheddite loads just about duplicate the Winchester loads.
I load STS hulls with 17.1 of Clays and a WJII wad (26gm of 7.5's). It's my favorite light caps and 5-stand recipe. I've been shooting an 1100 Comp for about 3 seasons. I've never had this trouble before, but it's never been this cold, either. The 1100 Comp has been an excellent gun.
This is the first year I've loaded off-brand primers in any quantity. I've been loading WW for 12 years, before now. I noticed that the Cheddite's seemed much dirtier, and the Nobel's crono'd slower, but not enough to concern me.
Like I said, it's just personal preference, but I'm sticking with the WW for the winter. I'll burn up the 4K of Cheddite's and Nobel's I have left when the weather gets better.
Once I use the Fiocchi primer then I won't switch to another brand as it is to my understanding that these primers are a few thousandths larger. I will, however, measure these to check for myself. Darrell
A lot of reloaders have experienced cold weather issues with the Fiocchi 616 and some have experienced some firing pin issues with the Cheddite. In any event, use reliable loading data for either. There are some wide discrepancies between powders and powder company data, especially for the Fiocchi 616. Neither primer is oversized and are within reasonable standard 209 size tolerances. The contours of the primers may differ from some standard primers, but the diameters are close.
Quack Shot is 100% correct.. I would suggest contacting Kevin at Downrange.. He has tested ALL primers and has much to say about what is good.. and what is not.. Flincher is actually right about the choice of wads in cold weather.. but if the primers are not doing there part.. NO wad will perform correctly..Again.. a call to Kevin would be useful.. and Fiocchi are NOT cold weather primers.. I love them in summer..but under 40 degrees there performance is marginal at best...
