I only use 2208 and reloaded 26 150eldx 150lrab and 175 bergers this other box was one I thought I’d sent back with a friends rifle my bad clutter around the bench is bad for sure

I mean I can't really talk, I have at last count something like 15 different typres of .223 bullets sitting there. The big red stack of 80 ELDMs is pretty hard to mistake though

For 1 grain over max I think something else is amiss, check your scales or powder.

I shoot both at the same COAL (2.8"). Unless you are doing something like a crazy 3"+ COAL I can't see how this happened.

Powders new 2208 bought new buy me custom chamber loaded to 2,935 scales are good against the beams can confirm it was jammed

ELD X to not M

You only should do it once!

I wouldnt have thought that was hot enough to blow primers with 162g. It's only a grain over max, even jammed. Still, I dont know your rifle.

Highly dependent on alot of factors. Assuming book max is going to be the actual max in any rifle is not a good idea. All it takes is a chamber with tighter tolerances than a sloppy factory and some brass with a couple grains less capacity than the brass used for the book data and all of a sudden your grain over max is more like 5 grains over. Short of having proper pressure testing gear, Velocity is always going to be the best indicator of pressure.

Correct 2650fps is what it measured on the chrono which seems pretty damn hot for 2208 in a 16” barrel it is a custom cut chamber to not factory

Grt suggests the pressure was at 81k psi based on velocity

Yeah, regardless of the powder charge the book says is max, for that sort of velocity in a 16” with the 150s its got to be a fair nudge over saami max. Then you accidently stick a 162 in front of it, no wonder the brass looks like that. Could have been alot worse!

Yip it appears my chamber behaves like (for arguments sakes) a tikka chamber
would if it was 3 4 grains over book max cross checking velocity’s at 42 grains the brass looks fine and the bolt lift is fine but the velocity tells a different storey I’ll call it a very efficient chamber uses less powder

Were the granules not different enough to be able to pick them out?
