Is there a book or a website that compares primers? I haven't been loading that long and am wanting to know what different brands can be swapped to do about the same job. It seems the the run on primers and powder are on!!!
 
Yes there is, yes you will be sad to know that Smokless is correct.

There is no spoon.

Basic type primer compounds(rem, fed) are less stable, than standard type compounds(win, cci) Otherwise the output and duration is SSSSOOOOOOOOO close between them all, it is no different. The only "kinda" difference is to what speed/rate they build to that total output.

CCI BR4 - match primer with a thicker .025" cup.
Federal 205 - Mil-Spec cup thickness according to Federal - okay for 5.56mm. .0225" cup thickness.
Federal 205M - same as the 205 but the match version.
Magtech PR-SR - .025" cup thickness (not much feedback yet on this new primer as to AR15 suitability but with the same cup thickness as the Rem 7 1/2 it looks good so far)
Remington 6 ½ - thin .020" cup, intended for older, lower pressure rounds Remington says do not use for the .223 Rem or other similar pressure rounds. Good for .22 Hornet, .30 Carbine.
Remington 7 ½ BR - A match or "bench rest" primer. Lyman & Nosler classify this primer as a Standard. Remington says the compound is the same as the 6 1/2 but with a thicker .025" cup.
RWS 4033
Winchester WSR - some piercing issues noted when changed from silver to brass cup. Cup thickness is a bit thinner at .021". Most say they are good to go for the AR15 despite that, probably because of the hardness of the cup. Some feel they are less resistant to higher pressures.
Wolf Small Rifle SR - soft, sensitive copper cup, not recommended for AR15/military rifle use or high pressure rounds.

Small Rifle Magnum

CCI 450 - same thicker .025" cup as the BR4 and #41.
CCI #41 - commercial version of the fully-qualified DOD primer for use in U.S. military ammo. With this primer there is more 'distance' between the tip of the anvil and the bottom of the cup than with other CCI SR primers. .025" thick cup. Same primer mix as CCI 450.
Remington 7 ½ BR - A match or "bench rest" primer. Hornady, Handloads.com, and Chuck Hawks classify this primer as a Magnum, differing from other sources that classify it as a Standard. .025" cup thickness.
Wolf Small Rifle Magnum SRM - hard, less sensitive brass cup intended for AR15/military rifle and high pressure rounds.
Wolf Small Rifle 223 SR223 - "This is the newest primer available in the Wolf line. It is ever so slightly hotter than the small rifle magnum primer and it comes with a brass colored thick cup. This primer can be used in place of the SRM primer or used when a different powder is used that is hard to ignite."

Large Rifle Standard

CCI 200 - mild in brisance. Hard enough for use in semi-automatics.
CCI BR2 - same as the 200 but the match version. Hard enough for use in semi-automatics.
Federal 210 - medium brisance between CCI/Remington & Winchester. Do not use in semi-automatics.
Federal 210M - match version of the above primer. Do not use in semi-automatics.
Magtech PR-LR
Remington 9 ½ - mild in brisance.
RWS 5341
Winchester WLR - the hottest standard primer. Hard enough for use in semi-automatics.
Wolf Large Rifle LR - all brass - Used by noted match shooter David Tubbs who says: "Be sure they are seated into the case - if not they can be hard to ignite. Russian primers use a different sinoxide compound (closer to the European type), which, in my testing, consistently delivers better extreme spreads over Federal..." Hard enough for use in semi-automatics.

Large Rifle Magnum

CCI 250
CCI #34 - commercial version of the fully-qualified DOD primer for use in U.S. military ammo.
Federal 215 - original magnum primer

NOTE 1: According to Speer/CCI Technical Services - Both the CCI 550 Small Pistol Magnum and CCI 400 Small Rifle primers are identical in size. Both primers use the same cup metal and share the same cup thickness. Both primers use the same primer compound formula and same amount of primer compound. They can be used interchangeably.

There are still plenty of Mag primers, both small and large. Just use them and of course start low and work up. If you already have an assortment of different primers, just use them up one brand and type at a time. You really won't find much difference on target at the ranges we hunt. Heck, Mag primers are all I use in my .223. Both AR and Bolt guns.

I use CCI 200 in my 300saum loads, even though the books call for a mag primer. Never had any problems, so I will continue to use them.

The thing that [beeep] me off about that info put-up, that someone thinks there is a difference in primer cup hardness; for the sake of "mil-spec, or semi-auto" use.....
The way that they make primers less sensitive, or "mil-spec" has nothing to do with hardness of the cup, it's the anvil height!

Whats really sad is there are people like you that always have something smart to say about others questions making them not want to ask questions and trying things that they shouldn't.
