RIO PRIMERS

[Andy]

Thank you everyone for the tips. Mike, you're late to the soup kitchen you don't get the soupy. But then again, I've seen your reloading "room". I do not feel sorry for you : )

BWAHAHAHA!! Let’s say I’m not looking for primers!!

I use Win 209 and Cheddite 209's, have 3000 of each right now. I do use them interchangably. I look at my loads from Hogdon's and Alliant's reloading sites which most of the time will list loads with each of the primers, and there is not any significant difference. a 200psi difference and 25 fps is really not a problem with the low pressure, under 1200 fps loads that I gravitate toward. I have not noticed any problem with seating those 2 primers. I load Gun Clubs in 12 ga, Cheddite/RST 2 1/2" in 16, and AA and GC in 20's'. I dont sub Fed209m or CCIm.

Prior to the current primer shortage one of my shooting buds often commented that Rios are too much trouble to use. I called him earlier and asked why that is ..... in addition to being somewhat oversize and thus hard seating in once-fired American hulls, their leading edge isn't as radiused as other 209 primers and can cause jams (in the seating station) of progressive loaders like MEC 9000's.

Ugh...I'm new to this. I have 5,000 primers for sale cheap : )

Shame on me! The data I posted was from Tom Armbrust, not Tom Roster

The digging around I have done in the past and info from powder manufacturers was as long as you are not substituting a Federal 209/209A or Cheddite 209 for another 209 style primer the difference is minimal and may even be lesser pressures/velocities depending on the original primer called for. The Federal primers are hotter than Win, Rem, CCI, Fiocchi, Nobel, Rio. Since we are loading on the lower end of SAAMI specs there are viable substitutions. Off the record info from manufacturers is yes, you can substitute the lower burn temp primers. On the record info is dictated by lawyers. It is what it is.

Mike are saying that Cheddite are also hotter?

That's what the data said. Remember though that we are loading on the low end of SAAMI specs too. Not as hot as the Federal 209/209A but burn hotter than the other 209 makers.

I don't use Federal or Cheddite so I can't share any results. I know guys who use Cheddites instead of Rem, Win, etc with no issues.
