Leading????

[Freightman]

I sized a 155g FN boolit to .308 in my sizer and got lots of lead so will sizing it to .311 hurt a 308 rifle and keep it from bieng to small and causing leading?
I just started casting am using WW lead and a little tin mix.

Maybe. Where in the barrel was the leading, what case did you load it in, and what was the charge? Did you slug the barrel yet to see what size to start with, or are you just using what was on hand to see if it worked?
