AR buffer weight vs. long distance precision/accuracy

[RSKYBSNS]

I'm curious to know if anyone has any experience when it comes to different weigh buffers and how they may affect your LONG RANGE accuracy and precision.
I've been running a 14.5 in some fairly long distance matches these past couple years and just recently acquired my suppressor.
I learned today, apperantly I've been running a Carbine H buffer (3 steel) in it while unsupressed for a long while. I thought it was an H1 with 1 tungsten 2 steel (buffer isn't marked). That buffer was in front of a regular Aero precision spring. I noticed my brass was getting kicked out at 1 o'clock pretty far away after running suppressed. So I decided best to make a change.
I just installed a Super 42 spring, with a buffer that has 2 tungsten 1 steel (H2). The spring itself is has a decent amount more resistance compared to the regular Aero spring, as expected. Adding the H2 it kicks my brass at 3 o'clock only a few feet away, which I believe is more favorable.

Now, since that's the back story... I'm curious to know if I should expect my current dope to change at range of 700yds and in. I'd have tested this two days ago, but when I noticed where my brass was landing I figured things were moving a little too fast.

I cannot see how different weight buffers possibly could have any effect on the bullet …

How an AR-15 works:

I would think not …

Initial though was wondering if an increased resistance due to springs/weights would have any direct effect on chamber pressures becaus of the bolt unlocking later or slower, possibly affecting velocity thus poi. Understanding that yes, the bullet should be long gone out the barrel before the bolt even thinks about unlocking it was still one of those things that I'm sure someone somewhere has tested long before I ever thought of it being a thing.

I play with suppressors and buffer weight tuning a good bit and I can't report having any poi changes from moving weights around.

I can report malfunctions and reliability changes, so if your blood pressure raises over malfunctions and lack of reliability like mine does, definitely expect a point of impact changes caused by the shooter lol.

Understandable🤣 as long as they dont happen on the clock then I'll be in a much better place🤣
In your experience, does adding more weight (slowing down the carrier) tend to have more or less reliability issues. Like lack or cleaning, dust dirt and junk in the way of the carrier? Does it have a harder time blowing through that then coming back home?
