Hello,
I finally slugged my Lancaster 303 oval bore and it mics at 0.300/0.317 on both left and right.
Which bullet diameter would you guys use?
I assume that a soft 311 bullet would upset just fine in the bore, but...
Curl, what's the story on your 280?
BTW, the bores appear to be mint. However, it would be hard to see wear on that type of rifling.
Thanks for the help...
