buffers, 0&1

[philevans]

using handloads in the 55-69gr range with 25.0gr, CFE or Varget or RE15.
S&W buffer is 3oz and ejecting at 1pm(maybe its over gased).
installed H buffer which is 4oz - still ejecting at 1pm.
What now?
a H3?
should i worry till i get 3pm ejections or just leave it alone.

Where is it ejecting bulk ammo? What does the reloaded brass look like? Any high pressure signs? 25gr Varget isn't max load for 55gr bullet I know but need to check this out. I wouldn't worry if no high pressure signs unless it stops throwing 'em out. You could go with a heavier buffer/spring or a heavier BCG but as long as it's ejecting, why bother?

Everything I've read seems to be 50-50 on worrying about ejection pattern. As long as everything is working, I would not worry about it. Now, I did add an H2 to my M&P OR. Not because of ejection but to help reduce beating up the rifle. I tested it with about 800 rounds and have had no issues. Oh and BTW, IIRC they are over gassed. Got to remember that they are designed to shoot all manner of .223 and 5.56 and still be reliable.

The general rule is to use the heaviest buffer will fully cycle the action, using the ammo that you shoot the most.

I have an H2 buffer in both of my AR's. I keep a spare carbine buffer with them both just in case. I know that a carbine buffer works all the time. It may be a little harsh, but it works.

Examine the brass pile after shooting and see if it's really 1 o'clock. I bet it's more like 2 o'clock or 2:30, which is perfect. Make sure your loads aren't too hot for your rifle. Using those powders in the small 223 case you can get too hot really quick, in less than a grain.
