These are thicker and resist firing pin punctures and slam-fire ignitions.
You may be able to get by with(6 1/2's) bolt action rifles and moderate hand loads, but I wouldn't do it.

The 17 rem, 204 ruger, 222, 223 all need the thickest/toughest primer because of the very high pressures involved in small rifles. Theses same rifles in semiauto/AR-15 configs are even at greater risk of Slam-Fires caused by the floating firing pin. The proper primers were specially designed by Rem are the 7 1/2's.

How the heck do you figure that?, the 7 1/2 is a bench rest primer which means that the quality control and consistency is tighter for more consistant ignition. It has nothing to do with the cup metal being thicker or being able to handle higher pressure loads. Whoever told you that was just trying to sucker you into buying the more expensive primers. Every single loading manual says nothing about having to use BR primers for semi auto's.

Well of course Remington will push for you to use the more expensive primer, they make more money. Nosler, Lyman, Speer, Winchester, Hornady and Barnes make absolutely no reference to the need to use match grade primers in semi's. the white box CCI primers specifically #34 and #41 are made to military spec. Wow the things that uninformed people will fall for. I guess the 30 plus years that people have been using standard primers everyone was all wrong, as well as the biggest names in the industry.

The 6 1/2 has a softer cup and a lower brisance. It is very useful in small capcity cases of lower pressure like the 22H, 25-20, 32-20, etc. As mentioned it is not for use in the smaller higher pressure cartridges of the .222+ family. The 7 1/2 primer was developed especially for these smaller higher pressure cartridges. It has a stronger cup and more brisance conducive to the use of ball powders. The WSR primer is pretty much the same as is the Federal 205.
There are small rifle magnum primers such as CCI 450s.

I'm such a dupe that, I'll side with Larry, and on the side of safety.

Some makes may also utilize a thinner cup to guarantee reliability, although this is not always the case. The Remington 7 1/2 Benchrest primer, for example, uses a fairly thick cup. Sensitivity can become an issue here and may increase the risk of a slam-fire.
So, You go ahead and ignore the warnings of the Primer manufacturer, Bullet manufacturers and Powder manufactures. Shoot-em up, have fun. Just make sure you tell all your fellow shooters at the range to stand clear of you and your rifle.
