AR-15 5.56 Primers... CCI # 41

[ExtremeX]

I'm looking to make my first primer purchase.

I understand these primers are for firearms with floating firing pin to help prevent slam fires.

Does anyone else make primers that fit this criteria? I dont mind buying a few different brands and trying them out...

Also, does anyone make "match grade" primers for floating firing pins?

I use 450s because of the harder cup. But most CCI primers have hard cups anyway. Just adjust your first loads as necessary. I try to stay away from the softer WSP.

Here is a primer cross reference chart to help with is A the same as B questions.

I'd recommend just staying with the CCI #41, adjust your loads, powder and bullet type but keep the primers consistent till you find the one that works the best w/ your rifle.....

You don't really need the CCI #41 which is a few buck more per sleeve than the CCI 450 or CCI 400 (depending which powder you choose). I've used both CCI 450 and 400 for years and are quite happy with them. But if you happen to see CCI #41 on sale then by all means go for it.

Properly seated primers in properly maintained firearm will not slamfire no matter how hard or soft the primers are. I've always worried about proper primer seating depth and never worried about which SRPs I'm using.

Yeah, but wouldn't it suck to have a slam fire at the range and then find out the guy 3 lanes down from you is ATF?

The make the #41's for a reason. Slam fires may only occur infrequently, but they can and do happen. I guess it's all a matter of whether you're willing to deal with the consequences of it when it does occur.

There's nothing illegal about a slamfire. It is unsafe fot the gun,the shooter and even the guy three lanes down but, malfunctions are not illegal unless you keep shooting. I've got zero problem shooting near LEOs and experiencing a malfunction. There will be zero legal consequences if this ever happens.

Do you think Federal, Remington and Winchester use CCI primers for their .223/5.56 loads?

[Ken Woodford]

I will admit I am not the most knowledgeable reloader but I am also not the dumbest. But it is my opinion that unless you are shooting competition you won't know the difference.

For example I was buying primer just the other day. The guy tried to sell me BR-4 from CCI. He said people on the net are getting 30 to 50 FPS more using those. Really 30 to 50 FPS is going to make a difference? Not according to any ballistic table I have ever used.

And CSACANNONEER is right...shooting next to a LEO and have a malfuntion is not a crime. Nor would a leo probably do anything about it.

I don't know about that. I know some Federal agents who would offer their help and expertise in trouble shooting any problem.

I picked up the CCI #41 primers to get the ball rolling on the reloading process. Its the only small rifle primer I could find locally and Im just happy I didnt have to deal with any shipping or hazmat fees since its the only item I bought.

Worked out to 3.5 cents per primer... not the best deal but it could have been worse.

Thanks everyone for the help and links. I did learn something from this thread.
