220 Swift Chamber

[Jdaniel343]

I just got some cerrosafe and cast my 220 Swift chamber. (Winchester heavy varmit, H&S stock, piller bedded with bedding block).
In the past this rifle shot 0.50 MOA or better with tuned up brass and handloads.
All dimensions from the cast are approx. 0.002 under sammi chamber specs except for the neck.
The chamber cast measures 0.262, my fired brass measures 0.258 to 0.259. My reloaded case measures 0.253.
Is this ok?
Thanks

Seems like your moving the brass a lot, the fired brass is good but the loaded case seems awful loose to me @ .009 under neck diameter....... Not terribly bad but enough to wear your brass out sooner than needed.....
