Would someone please post the primer heat rankings again? It used to be in one of the spreadsheets which I have since lost or misfiled. I have a mixed collection of primers, hulls, powder, and wads, and wish to avoid ill advised loads or fruitless testing.

TIA

I copied this from a 2010 spreadsheet.

Primers from Mild to Hot with Equivalency
1. CCI 109, CCI 209
2. Rem 209 Premier STS, Rem 209P, Rem 97
3. Win 209, Ched 209
4. Fiocchi 616
5. CCI 209M
6. Fed 209A

Primers
"Recently we had a thread on our forum discussing primers and acceptable substitutions. Below is some information that I have accumulated from various sources."
CCI 109 and CCI 209 are ballistically identical and can be interchanged. Alliant Powders Reloaders Guide 2004.
(I have confirmed this over the telephone with CCI staff several years ago.)
CCI 209M (magnum) is hotter and cannot be substituted for CCI 209 and 109. Alliant Powders Reloaders Guide 2004.
Rem 209 is hotter and cannot be substituted for Rem 97 or Rem 209P primer. Alliant Powders Reloaders Guide 2004.
Rem 209P is interchangeable with Rem 97 primer. Alliant Powders Reloaders Guide 2004.
Federal 209A is hotter and cannot be substituted for Federal 209. Alliant Powders Reloaders Guide 2004.
Rem Premier STS primers can be substituted for Rem 209P primers. www.remington.com/ammo/reloading/shotshell.htm
Cheddite 209 can be substituted for Win 209. Posts on various forums.

The chart looks good with the exception of the Fiocchi 616. Very optimistic placement for a primer that doesn't always perform well with large doses of slow burning double based powders, especially when the temp drops into the 20's.

The best primer chart I have ever seen, is the one with only US made primers. The reason is because Euro primers are generally used to ignite single based powders and don't really handle double based powders that well. Very tough to rank primers that don't handle double based powders well, because they weren't designed to ignite them.
The exception seem to be Cheddite primers.

I bought some RIO primers that are supposed to be the hottest euro primer. They do fine with 700-X, but I think they will fall down when it comes to Blue Dot, Longshot, Steel and a few others.

I will try it with a buffered lead load using Steel powder that I recently had tested and see what happens over the chronograph.

Thanks Mark, I have a good supply of Rio primers which work very well with 800X, and I look forward to hearing what you find. I hope they work well with Red Dot but I will withhold judgment until I find out more.

Thanks

Brewster11,

800-X, despite it's large grain size, is very easy to light off. I am sure that the RIO primer does well with it.

Red Dot shouldn't be an issue with RIO's unless it is a light load with low chamber pressures.

I am going to cold soak some ammo for 24 hours and try, 700-X, Green Dot and Steel powders.......but give me a month or two, still a bit nippy to be out chronographing loads in ND!! There is also a 4' snow drift between me and my patterning board area.

Cheddite does not always act like the win and fall to the cooler side. For 12 gauge using titewad the pressures for the cheddite primered loads have the most pressure of all primers. Just an FYI

^^^^^THIS^^^^^

I've been working up some 2.5" 1oz loads with longshot and RIO primers and they are performing very well.

UncleDanFan,

Nice to hear.....more options.

Nothing definitive here, just a experience with one 16 ga load
Herters hull
1oz lead
sg16 wad
18.00 GD
This load is 35 fps faster over my chrono with the cx2000 cheddite primer than with a W209. No idea on pressures

difference according to Cheddite themselves between their cx1000 and cx2000
