It really is not the rifle but the brass. If you have a loaded round of ammo with the brass you are going to use then measure the neck of a loaded round and subtract 2-3 thousandths and that is the size bushing you need. I measured 3 different types of brass and the following is the size bushing you would need for the respective brands. Winchester .330, WCC NATO .334, Lapua .335 hope this helps.
Ritten, I have tired to get a sack a few times but it was always something. Either they didn't have it on location or I flew to the job ect. In my reading everyone states the corn cob will shine the brass better. Granted cleaning is the important thing. Next time I am running low and drive to work I might try to acqure 50lbs.
Where are you getting tumbling media in large quantities? I have a big sack of walnut husks that'll last me quite a while but I wouldn't mind having some more on hand
The Drilling industry uses pallets of it so if the rig has some on location usually they will give me a sack if I ask nice.
Excellent writeup! I will be using this to help me perform my first set of handloads!
Because the Giraud makes it so easy I trim after every firing. You only HAVE to trim once the brass is longer than the Max allowable length found in your reloading manual.
