I have the Saco 60 gr for my mini 14  -- feeds ok,, (RCBS 55gr too)   I think it is ez to pump it up a little to much and lead  up the barrel --  but I"ve had fun when I get the powder charge right..........    I shoot a lot of light loads  and hand cycle each in ...
  I like the 14, but wonder -- a mini 30 would shot cast better...
 
Midsouth's -- Lee -55gr Bator,  is nice too   at $20..
