What the ^&*&^*&^*&^*&^*&^ Does 'Slugging the Bore Mean'?

[WaddWatsonEllis]

I am so new at this I squeek ...

So if I say 'Send me a PM to let me know how it works out', I mean it.

I think I have an old Pedersoli Cap N ball .50 cal that uses .490 balls  .... I might try it too!

Old method,put your ball between two pieces of steel and roll back and forth with top piece while pressing down elongating your ball and reducing the diameter a little.Quarter by one and a half or two inch flat stock,scraps 6 or 8 in long works pretty good.Remember the bore your forcing into is aprox. .450 the groove depth is .458.

.490 - .450 = .040            45/70
.451 - .421 = .030            .44 Spec / Mag

Really only dealing with .010 more ball with the .490 in the 45/70. 

Really do like the rolling between plates suggestion and may well use that for .30 Cal bore.  Using a .32 ball did not leave much of an area to mic.

Might start using egg sinkers in those.
