Cheap .316 mold ?

[hunteatfish]

hello this is my first post here and love the forum. I have a 1891 argentine that I sporterized. it has a j.p sauer and shon half round hafe octagon with full rib think it came of a 88 or a mannlicher. it is marked 8mm only and I have chambered for 8x57 but found out it is a true 8mm slugged the bore. came out .309 bore .315 grove. I have made paper patched 308s loaded up with 3031 and shoots fine just some time in the pp bullets. I'm locking for a cheap mold other then the n.o.e. out there can I take a .312/.314 lee mold and polish it bigger. I'm trying to say cheap here I have no money in the build had the barrel given to me and did all the work. just my time if anyone have any ideas they will be helpful. ps I'm trying to get up pics of it. tanks...troy

You might look around for an old Lyman 311299 from the gray and black box era . I found one on Ebay that cast at .316 on the body but for the use I had in mind I had to add a DD band to the nose .

thanks for the reply jack. ill keep a eye out for one. any other ideas from other people will be helpful. I'm thinking of powder coating any I get that adds a .0001 or some to the size.

Several years ago there were a couple of group buys of Lee 6 cav. molds. "Fat 30" and "Fatter 30", were copies of 311407. IIRC, some of them cast as large as .316 - .317.

Amy chance that you could have a .318" bore on your 8mm? That seems more normal to me.

This is my thought as well.

My Gewehr 88/05 slugged to a size similar to what you're measuring, before I ran a lot of copper remover through it! :D

It's a true 8mm bore like what the 8x51 mauser had I looked up the numbers on the barrel seams to be 1910 year of manufacturer slugged 3 times got 309-315

It's a commercial j.p Sauer and sohn 8mm barrel .315 grove made in suhl Germany

The bore was cleaned many times with sweets and powder solvent. Strange thing is now green or blue coloring came out a old gunsmith who worked for Sauer seed it's because it most likely only shot Nickel Plated bullets. With I can ask him more but past away last month a 101 years old

cupro-nickel.
that stuff is hard on barrels.
the paper patch bullets probably got most of it out.

the lyman number referred to above is the 314299 not the 311299 they were both actual mold numbers but the 311 mold is for 30 cal.7.62 rifles and the 314 is for 31 cal 7.65 rifles.
to find one of the older series of lyman molds that would make 314 or maybe even 315 with luck and lino-type would still set you back 70$ American plus shipping.
and you'd be taking a chance on what it really pours.

a 2 cavity NOE 314 or even their 316 series molds will make a nominal +.002 with regular old 3% antimony alloy.
personally a 2 cavity mold I know will work with just about any scrap alloy I can find is worth 20$ more.
especially versus buying 2$ a lb alloy that may or may not make my mold sorta work in my rifle.

I have Lee-mented a C312-185R to .316" for a mosin nagant. May work for you. They're under $30.

Thanks for the correct numbers and the info

looks like that one will do the trick petroid. any only 21.99 at midway thanks for the help going tomarrow to shoot it more with the pp boolit at 100 yars and work a load up on my 1909 arge in 7x57imp.

Look up Lee-menting to see what has been done to that mold before you buy one.
