Difference in primers?
What is the difference in primers? I mean one type. Small rifle primers. I cant find a recipe that includes CCI #400 for .223 rem. Are these suitable or interchange able with say Remington 7 1/2?A you tube post by DeAndre McInnis "Erwin Rommel was a smart mother f@cker."

if you are near max loads it may be wise to back off 10% and work loads up again.

No I am starting with the suggested start then I am going to work my way up if needed. I will be shooting these loads in a Match AR 15. I was conserned that the CCI 400s may not be heavy enough for this rifle?A you tube post by DeAndre McInnis "Erwin Rommel was a smart mother f@cker."

The only time I would be concerned about switching from one "small rifle primer" to another is if I had an established max load because a different primer may make it over max. If your just starting to work your load up and your data calls for a standard primer you can use any standard or BR primer. I recently picked up some Rem. 6 1/2's. When primers were in low supply the only thing I could get was the 7 1/2 BR. I tried one of my "bulk bullet" loads with the 6 1/2's to save the BR's for varmint use. So far I have not noticed any difference. I can still hit golf balls at 200 yards with my VTR-15.

Thanks Motor that was my big consern that the CCI 400 arnt BR or Mil spec. As I will be using them to roll up some loads for an AR15 Match rifle. I had bought my Lymann manual when I picked up the primers. I didnt notice that they were loading with Remington 7 1/2 primers until I got into some reading.A you tube post by DeAndre McInnis "Erwin Rommel was a smart mother f@cker."

My friend uses the CCI 400 for ALL his AR loads.
If it wasn't for the "primer shortage" I would be using the CCI 400 in my AR but now since I have worked all of my loads up with the Rem. 7 1/2 I've stayed with Rem. but I'm substituting in the 6 1/2 for my "fun" shooting loads. Like I said though I haven't noticed any difference in performance/accuracy yet.
I just picked up 200 CCI 450's in a package deal so I'll be looking to load them into some "fun" shooting ammo. The old rule of thumb is: A magnum primer is equal to 1 grain of powder increase. So I'll most likely look for a load that has room to move upwards and reduce it 1 grain. I have at least one load that uses H-335. It may be a good candidate for the 450 primer.

Those regular CCI 400 will be just fine in a AR I used them exclussively in mine when I shot highpower.If you find yourself in a fair fight, your tactics suck!
