bumping up bullets - swaging?

Is there a book or pamphlet or  other help  on the subject of increasing the diameter  of lead bullets by swaging?  I need to  increase the diameter  from .320"-.321"   to .327"  on   some bullets  for  a rifle with a .326" Bore. Is it correct to go for a bullet either at or .001" bigger than   groove diameter ?  This is for a .32 - 40  using BP  in a Rem. RB.  Thanks for  help and opinions.  WB

Contact Corbin Mfg.  I had them make a reloading press type die (7/8-14 thd.) of .226 dia. for bumping up .22 cast bullets.

Thanks for both suggestions.  Just to educate me,  why can  bullets be .002-.003"   under bore size with Black Powder?  What  may be the effect of the under size?   Will some gas go by the bullet , or will it be bumped up  when shot?   WB

Black Powder loads will "Bump" up the bullet right there in the throat as the powder is a true explosive. It all lights up nearly instantly and gives the Bullet aSledge Hammer blow. It is not progressive as is most Smokeless powders.
Now as to your large .326 Bore size. You may have a re- Bored  barrel. Might be  .33 caliber. Not sure about the Bore size for .33 caliber as over the years the Bore and Groove sizes for .33s have been all over the lot. Some Groove sizes 
were .333 which would mean the Bore size could be as small as .328. Many were .338 Groove and I have one that slugs out at .340. So you need to do some ongoing research. Many of these old Barrels were re-bored, it was a common practice in their day. HTH Regards FITZ-G Smiley

To bump up bullets get a piece of steel plate at least 1/4 inch thick for the bullet to drop on and a 4 foot piece of hard copper or plastic tubing that is straight, inside dia just a little larger than your bullet, stand up the tubing straight up and down on the plate, drop the bullet base down through the tube it will bump up and will be ready to run through  your luberesizer. If you hear the bullet rattling down the tube it won't  get enough speed to bump up use a little larger tube.  HTH

I would highly consider having a proper bullet mould made. Beagling, swagging and all other types of money saving short cuts may very well cut you way short on the accuracy potential you might be trying to achieve. An as cast proper fitting bullet just cannot be duplicated no matter how hard one tries if searching for the best in accuracy based on my own experiance. Moulds are really not that exspensive when one takes everything into consideration and a very wise investment and you can easily sell your mould to help make up for the costs if still in good condition. Try to Beagle it and ruin it and it is absoulutly worthless and you right back to having to buy yet another one to try and take its place anyway.

Is there a big demand for used 0.327" dia moulds?

It's my understanding that in the old days they has a thing called a Pound Die, the idea being that you put your cast bullet in it and then pounded it with a hammer or whatever to being the bullet up to the final dimensions. I further believe that this process was with bullets to be used with the paper patch.
In this day and age it may be just easier to have a custom mould made as advised by J Louis. You can never have too many moulds, can you ?.
The one potential advantage I do see with the swaging idea is that you will end up with a perfectly cylindrical projectile, with little chance of it having any voids inside.
You might like to run your question past the good folks at Corbin.
Mike.

LEE makes a mould for a 327-328 RN 200 gr. that may be just what you need.   They are relatively inexpensive, especially compared to a custom mould that MAY work for you, and MAY NOT.

I think you will eventually give up the notion of BP in a 32-40 as a bad job and go to smokeless.  It is true that one can get good results with an undersized bullet with BP, if it is presented correctly in the bbl.  With smokeless, it is a good rule of thumb to use a bullet slightly larger than groove diameter.

If you are going to try to load fixed ammo, probably you will have to go to a smaller bullet, so that the ctg will enter the chamber.   It may be a long, bumpy road that you are embarking on, but you will have a lot of fun and learn a lot of stuff.

When I tried this I found out quickly that much more expansion takes place in the grooves than on the O.D. unless you swage 'em already lubed.   

The "pound die" was used for smooth-sided bullets to be shot  with paper patches out of muzzleloaders.

For some 8mm bores, I suspose.....  I had one of the three 185 grain moulds I bought through a recent group buy cut .325".

Phil,
Did you run into a slightly oversize 8mm "S" size barrel?

I have an old Lyman mould that casts .327 or .328.  Not a heavy bullet.  Maybe 150 grains.  If you would like it, PM me.

I think we have some confusion here - reading the above, it seems to me the the rifle is actually .326 groove diameter, as WB considers .327 to be  ".001 bigger than groove diameter"...
