Changing components?

I'm working up a 77 grain .223 load using the Nosler guide, and Modern Reloading 2nd edition. I'm changing my cases and primers they list and starting at the bottom of the published loads, I'll be using LC 5.56 brass and CCI 41 primers. I know LC brass has a little less capacity, and the load from the Nosler book is a 5.56 load, not a .223. My question is, should I decrease the starting load by 5%?
 
Re: Changing components?

I have measured the capacity of my LC brass but the Nosler book used Nosler 5.56 brass for the 77 grain load, and I've never seen it anywhere so can't compare the two. I'm not very experienced, having just loaded blasting ammo so far, and every book I've read cautions against changing components. Am I making more of this then I need too?
 
Re: Changing components?

Yeah, kinda. A load like that will hardly blow your gun up, since a proof load is (what?) 140% of max? So, even if you get a flatten primer, which is a remote possibility, it's not something to get overly excited about. And, if that were the case, quit shooting and reevaluate. BB
 
Re: Changing components?

I'm not fully following.

Are you asking if you should lower the starting load by another 5%?

Or are you saying you have a load but want to change components?

I don't think there are any switch in components that would require you to drop the starting charge by 5%. The starting charge that any reloading book lists should easily be safe no matter what brand components you are using.
 
Re: Changing components?

RotARy15, yes I was asking if I should drop it down because I was using different components then what they listed, but you answered my question. I can get hung up on details sometimes, and just want to be on the safe side. Thanks for your replies.
