Lyman 457191: a little help please...

[lathesmith]

Hello, I am needing to make a die for one of our european friends, and I need to know the center to center lube groove measurement of either a Lyman 457191 or a Buffalo Arms 459300. This should be a 2-groove slug, around 300 grains or so. Your help would be greatly appreciated!

Thanks,

lathesmith,

My mold measures closer to .110" from center to center of the 3 lube grooves.
The bullet has 4 driving bands and was to be crimped in front of the forward driving band.

Hi John,
Thanks for your response! I am a little confused, the Lyman 457191 is a 3-groove bullet with NO crimp groove, like so:

But the Buffalo Arms JIM 459300 is a 2-groover, with a crimp groove:

I wonder if the dimensions between these two is similar enough? If the Center to Center measurement of the lube grooves is .090, then the driving band itself is only about .050 or so wide!
I need to do a bit more research, I'll see if I can find a slug similar to this in my collection out in the garage...thanks again for your input.

w30, thanks for the input! I see that it is very likely that the dimensions for this slug have varied somewhat over the years, and that kinda makes it tough to pin it down without an actual slug from the customer's mold! I'll see what he wants to do, it would be good to get it right the first time around...thanks again guys for the input, me and your fellow shooters appreciate it for sure.
