RE: Worse groups ever
 

No, what did the .015 patches look like before the buffer, it sounds like the original groups were poor because of thin patching and changing to .018 straighten things up...

RE: Worse groups ever
 

I couldnt find any of the .015 patches when i was just shooting those alone. My range is in thick oak brush littered with god only knows how many years worth of leaves and dead branches on the ground.

I too believe the .015's were to thin, but added the buffer patch really helped out a lot.
