Slugging a Rifle Barrel Video

[Texantothecore]

Thanks for posting this video. I had thought it was an hours long effort and have delayed because of that. I will be doing my rifle this week, whenever I get an extra 30 seconds of so available.

Boy what an eye opening video.

Thanks for the video. Enlightening to me as a new cast boolit maker. I will raid my fishing tackle tomorrow and look for a egg sinker close to my my 444 and 45-70 bores and/or maybe a black power ball I have.

I have a OLD SMLE with a barrel that I'm sure can't be slugged, as I push a .319 ball thru it I hit 3 inch to 6 inch spots that the ball sort of fell thru to the next little bit of rifleing that was left, .319 ball came out at .317, so the rifle sits till I can ever find a new barrel or afford it, rifle dated
1903.

I am new to casting and have some basic questions I will be needing more clarification on. The one in mind right now is about the final size of the cast bullet. When you slug a barrel and measure the slug are you looking for the largest measurement which would be the largest inside diameter of the barrel? I keep getting confused between groves and lands. Are the grooves the largest diameter and the lands the smaller or do I have it backwards?


Any way when you find the diameter from the slug do you still want the finished cast bullet diameter to still be .001" larger?

You have the grooves and lands right and the boolit should be a minimum of .001 over .002 may be better.


Keep in mind " Fit is King and hardness matters when it matters ".

Thank you for clearing that up for me. I did not slug my .357 but do use a .358 sizer.

Try first if no leading no need to slug your barrel But if you get leading then you will need to slug the barrel of a semi auto and cylinder of a revolver.
