I breezed through the group buys and didnt see anything current. I am looking for a group buy mold for use in these old classics. Anyone know of anything I didnt see?

The only group buy I know is the Mihec 311410 which is available in 0.311" and 0.316"

It is a lightweight though at 130 grs.

You might also look at Accurate Molds as Tom has several suitable designs and his moulds and service are top notch:

There is also the good old lee 312-185 mold. I have some boolits cast if you need to try some. Give me a PM if you want to buy a few to try.

Not for nothing but I'd slug each before buying anything. The Enfields can be all over the map on groove diameter. I have no idea on the Jap rifle barrels other than they're supposed to be .303's.

Just wouldn't want you to buy a .314 mold when you need a .316. :-)

The 7.7mm jap I understand is actually a 31 cal. bore and grove size can be all over the board too

the 7.7's used metford rifling not square cut rifling and can be pretty hard to measure.
kind of the 5-R of it's time but based on the LEE-metford rifling type.

I have three 7.7's, they're all .313-.3135/.302.
Not saying all 7.7's are that consistent. I size them all .314.
My 6.5 japs vary quite a bit more but are still decent shooters with the right loads. (jacketed)

I use the Lee .311 185 in an SMLE No.1 and two Argentine Mausers sized to .314. Shoots well. I size it to .311 and it also shoots well in my Win. 94 and my Marlin 336 30-30s.

Pretty versatile.

I find NOE's 316299 to be a good first choice boolit for these calibres as are any of the Fat Loverins.

For Metford type rifled barrels I usually just size to fit the throat, it works well on all my Long Lees.

Cast bullet engineering in Australia specialise in these molds. I use the tumble lube version in .315.
