Reduced loads for LC brass?

[M700Love]

Do I need to reduce load size for thicker LC brass over what I would for PPU? This is for 5.56 LC brass if it matters.
I have searched on here and google. Some say yes some say no.

Now you know that anyone offering good advice will say to start low and work your way up looking for pressure signs

I had to for 7.62 (about 1 grain), have no experience with 5.56.....

I reload mixed 223/5.56 brass (including lots of LC) and use the same load across the board. If that answers your question. All my friends do the same. YMMV

I load LC for my AR-15 and most will say that, for example, 4046 is usually good at about 25gr well for me I had to go lower to 24gr to not get pressure signs. But like stated here and everyone else that is smart will tell you start 10% lower and come up just so bad shit don't happen...........

Weigh them. 556 LC should weigh in the neighborhood of pmc and remington, 762 LC is about like Federal or PMC.

If you change a component work up again.

Check the water capacity of 5 rounds each, fired cases, and return and report.

Do not assume there is a difference. Measure. Quantify. There is no subsitute.

Try the following link on Accurate Shooter. You will see that LC Brass (recent)actually has more case capacity.

308 LC brass has less capacity than commercial.

223 LC brass has more capacity than commercial.

The internet will never finish stating that.
