So, I did a search for and skimmed and scanned threads with “buffer” in the title* but, still have some questions as I apparently now have yet another upper (also w mid-length system) that appears to possibly be over-gassed and I remember it being suggested to try a heavier buffer.
I should start by affirming: Headspace in the upper in question checks out okay …
The lower is a new PSA and I am ASSuming the buffer in it is milspec so I guess my first question is
Q-1: What is the weight of a “milspec” buffer?
Q-2: Is that milspec designated by an “H,” an “H-1” or an “H-2” ?
Q-3: what is a good source for reliable buffers of different weights?
Q-4: is this a safe (“good”) bet, to start with, in an attempt to see if the brass gouging goes away? https://www.midwayusa.com/product/1018146330?pid=711733
A bit of my confusion stems from fact that, in this index, the term “heavy” is applied to not only H3 but also H2 and iirc even H1 buffers:

Thanks in advance, the upper in question is proving quite accurate w factory 62 and 64 grain rounds so, I am hoping a tad heavier buffer will resolve the brass gouging (weird as I’ve gone 4 decades now with no uppers ever gouging the base of cases and now I’ve had two different uppers do it in as many months.
