I got a Lyman 320366 mold along with some others, kinda a pointy bullet, what I was wondering is could a guy size something that drops around 323 ish down to maybe .316 for use in something around a .314 bore?
I am trying to find a use for this mold as it’s to small for my 8mm K98
I don't know. That is a lot of sizing to do without totally wiping off the lube grooves.

I fear you would end up smearing the grease grooves out of existence or certainly distorting them to the point of uselessness. What you are talking about here is more like swaging than sizing. It could prove unsuccessful to the point of frustrating.IMHO, you would have better luck swapping that mould off (if you can’t use it in another gun) and finding a mould closer to your desired diameter.

PS that mould should prove to be very useful in a 32-40 or other 32 rifle cartridge, especially an older one with a slightly oversized bore.

Normally 3 to 4 thousandth is as far as you can go down and 4 is pushing it.
Fill the lube grooves first, that should prevent collapsing, then size in at least 2 steps.Originally Posted by RyanJames170
From experience I can assure you that won't work. When you size down that far it will wipe out the lube groves.
What would be the thoughts about dropping down to .318 to .319?
That should work OK. It looks like this was originally for 8mm rounds, but the 32 family should also be within reach.

I kinda figured being it’s 320 sizing on the mold that it was ment for shooting 8x57 that had the .318 bullets not the .323 as I’ve found most 8x57s that are chambered for the .323 bullets to be over .323 hence there is Lee mold out there that drops something like .327 ish that was specifically made for 8mm mauser in k98’s and the alike.
What are you wanting to shoot it in? You will have to order a custom sizing die for a 318 or 319. I don't think there are any common dies in those sizes.
a clapped out mosin that i have another thread about. as its to small for the only 8x57 i have.
Im working on an 7.7 Japanese that would shoot it as cast .
The American 32s are .321 nominal .

I think .318 or .319 will be to big for your mosin, most Russian mosins have .314 bore.

Maybe this is a sign. A couple years back I picked up an old Lyman mold as a door prize which I thought was a 7mm mold. Shortly after, I realized it was a mold for a 270. I didn't have a 270. Three weeks later I was gifted an old Sears 270 (actually a Win Mod 70 made for Sears). You never know what might happen.
The Mosin I have has a pretty bad bore that dose measure out to .318 in the groves and .303/.305 on the lands.
If you have a 314 H&I die you can hone it out with very fine wet and dry sand paper using an appropriate size wood dowel. You will have to go at it kind of slow and check it with a fresh boolit until you get to the size you want.
With the rifle getting a bullet mold to fit is the easy part with that rifle, getting a bullet to fit into the neck aria of the chamber with enough clearance to shoot is a whole other problem. As the neck aria in the chamber is barely fitting a .318 bullet, with no room for the case neck to expand.
Post some images of the Boolit or of the Mould Cavity?
Far as I recall, "320" ( or .321 ) were meant for the Smith & Wesson New Model 3 ".32 - 44" Target Revolver, or, for the Smith & Wesson
".320 Revolving Rifle", or, for the ".32 Ideal" Cartridge, and were not expected to be sized down.
.32 Winchester Special though was/is .321...
No idea who or what else ever used a .320 / .321 Bullet diameter as such.

The mold listed here Is the one I have and what the bullet looks like
Wow, that is a pointy bullet.
I have never tried to cast and size one with anywhere near that ogive shape.
