Did I just buy myself a paper patch mold? If so, guess I'll be here learning from you folks! If any of you know anything about the mold, let me know!

Looks like a conventional design with gas check shank.
What is the diameter? Assuming it's for 30 cal ( .308 ) it should be smaller, like .304 0r .301. It is not standard practice to have a gas check on a paper patch mold, but if you plan to go fast, why not. Cast a few and let us know.
Yep that’s looks like one of the originals.
Lyman cut them slightly different than what they wanted.
You have done well.
Looks like the Lyman 301620 200 gr. for paper patching.
That mould should cast a .301" bullet to be paper patched for 0.308" groove diameter.
They used to make two moulds to NRA specs for paper patching... 301618 and 301620. Both had gas check shanks for some reason, possibly an old .309" or .310" cherry foreground? Regardless gas checks aren't required when paper patching.
The Lyman Cast Bullet Handbook has the history of Harrison's load development and load data for .30-06, .300 Win and I think .308 Win.
Yes, you have done well!
Longbow
Neat! You got a rare one there. Just need a good 300 H&H model 70 bull gun to shoot them out of!
A Krag with a good barrel should suffice. I found an original that's .299x.308. I'm not going to make Camp Perry this year, this may be a part of future plotting. I've got a lot of slow burning powders that work good with conventional heavy bullets in the Krag.
Seek out the more recent, 10 years or less , threads for the NOE version of the 301618 with or without check step available in.301 or .303 dia and 172 or 212 gr versions .
They were worked up for the NRA for 1000 yd competition with 300 WMs as I understood it .
The GC step was to facilitate tailless wrapping . It allowed more variables to be removed like paper weight variation and base damage from paper impressions from a twisted or folded tail .
I had moderate successes with IMR 4350 in 308 but didn't chase it past "yep that'll work" . The 06's I had at the time were un cooperative at best 1 had a 1-8.5" twist , another was just plain too tight for anything cast . The last one ......we didn't get along at all , and I tried everything. I have a few loaded for a 4th rifle I just haven't gotten to it yet .
It will indeed!Quote:

No top punch needed. They don't get lubed.Quote:

I've been comparing it to a NOE spitzer I have seated out to the rifling of my Krag. That spitzer is over magazine length once out there. Looks to me like this paper patch bullet will be a perfect fit at a length that'll work through the magazine.
