thought I'd post some interesting findings on primer sizes-another post was talking on tight fitting federals- the difference in the federal 209 to the 209A makes all the matter- I grabbed a box of them off my loading bench tonight and was putting them in the plastic primer holders I made today- decided to try it out on the gun and cycle the bolt-and the primer fit -Snug- more so than I'm used to- then I noticed they had the brass color body compared to the copper color I normally shoot-HMMM? then looked at the box- they were the 209- not the 209A. Out comes the calipers- here's the results...
out of these boxes the Federal 209A was the smallest size- followed by the Winchester,CCI then the Federal 209.....they all fit -the cci and Federal 209 are snug though. So the Savage breech plug may not be as much of a culprit as some have made it out to be- the one with the "A" at the end of the Federal package would probably fit all the Savage MLII's fine...hope this helps -Getonit-
