I just bought three G&P midcaps for my VFC Scar-L (http://www.evike.com/products/30263/) and I just tried ~30 BBs in each to see if they were feeding well and no problem whatsoever. Now, I didn't put any silicone oil and I did not fully loaded and empty out them to "break them in". If they feed well, should I do something anyway or this "breaking in" phenomenon is just a myth? Thanks.
