The most desirable brand of Shot Shell Primers is?

[LUBEDUDE]

For years it was Win, then I found Rem to be more reliable. Now with a lot of winter shooting with light loads, as 35Remington mentitoned, Fed is hotter, So I do Fed for all.

anyone use the Rio primers? I picked up a sleeve because of price and there is very little data that uses them. Anyone who can tell me their equivalent in a common primer?

Thanks in advance.....

Never heard of Rio primers before so looked at their website. They have a little reloading info as you probably know but do not suggest an equivalent or give a comparison to other brands.

Oddly they say that their primers "Designed to work with the majority of existing powders on the market..." but give very few load recipes.

No ideas. Sorry.

I subbed them for Winchester in target loads and have not found any difference.. I did however pick a target load with lower pressure than usual (something in the 8500 psi range) in case they were a bit hotter. I've done this on many occasions without any issues.. when it seems to be an issue is when trying to ignite large amounts of slow burning propellants (Think Alliant Steel or Blue Dot) at lower temperatures is where I've run into "poof" loads.

Which ever your loading data calls for. I have used Winchester 209's for years with no problems in my target loads. More importantly you should follow the loading data to make sure you don't go over the pressure limits and do some damage to your gun or you. I would select a load that works for the type of shooting your doing and the temps that you will be doing it in. In cold weather 40 degrees or less I would select a load that generates at least 9500psi and a Winchester, Federal 209A, or CCI 209M primer as those are the hottest and will help to insure good powder burn. I don't load any targets loads that don't generate at least 9000 psi even for the hot summer leagues which have been well over 100 degrees. Like a diesel engine, heat and pressure are your friend at ensuring a good strong burn of the powder.

The good thing going for Rio is price! However, they are a few thousandths larger in diameter. So you may not be able to go back to WinRemFedCCI without experiencing slippage/fallout, in the same hulls. i.e., they stretch the primer pockets.

This is why I haven't taken advantage of the deep discounts out there.

I used WIN209's exclusively when I shot trap and skeet all the time . Used them in everything from the 10 gauge to the 410 with NO PROBLEMS .

Since I got outta the shotgun games I've been using CCI209 in the short 10 gauge , 12 , 16 and 20 . I also keep CCI209M's , they get used mostly in my muzzle loaders but also sometimes in the short 10 winter dove/squirrel loads .

To be honest I have no issue with using CCI or WIN primers in the same loads . But then none of my shotgun loads are pushing the envelope .
