load help needed on odd case from experienced loaders

[fffffg]

the cast bullet list has refused this post becouse i did not give the case name.. i guess there is no case name and this designation came from c and h, probably thier name to identify it.. ive been told by lelier and beloit to use 30/40 craig info which says 8 grains unique is a light load.. do any of you have any experience with drillings.. sorry to intrude here but im in a crunch,,all adeas appreciated, please state your experience with your suggestions so i can sort out where the suggestions are comming from.. . thanks dave. the original post was similar to this.

i need surely safe starting load for 9.3 x 72r/360 drilling.. this is not a heavey gun like a .366, or suel, this is a thin barreled 7 pound three barreled gun,,

i want to stay within safe limits for a small
diameter breach three barreled gun..
the smithy says the bore is .360, i get .362 at
muzzel but im not a smith and i didnt drive this one
thru.. the owner of c and h says its the caliber
mentioned above and is sending me the dies.. this
weirdo had a steel base and coiled? brass upper part
of the case.. a german idea circa 1926.. the ferosafe
cast shows a .363 diameter groove diameter at one inch
above the case into a very long lead. as i
said the dies comming from c and h, the cases coming
from l and l...
.360 and .365 30/1 bullets coming
from al at whitehorse bullets.. i also have 3/4 inch
teflon tape, (two wraps about .004- .005), and typeing
paper..wax checks, green foam, fillers etc. the
dies have a .363 expander which i oked becouse i can
sand it down smaller if needed.. the bullets are
plain lead base 190 grain comming lubed.. i need a
starting load to blow out some cases and see what will
come within a four foot circle at 100 yards..

the
books show what look like about 8 grains of unique are
pretty safe in alot of lead bullets loads in this
area..

would it be ok to start with the .365 bullet if
i have a .360 bore..?? or should i see what happens
with the .360 with a couple sheets of toilet paper
over the powder to seal it even tho its possible i
have a .362/.363 bore? ... any comments welcome..

I believe I have some book loading data for the 9,3x72R if you'd like to see it. Pretty certain I scanned it and have a file on it that I sent to someone else once upon a time.

I suspect this data would normally be for a bullet diameter of .366" which is the norm for 9,3mm bullets but as long as you know your barrel is less and you use appropriate diameter bullets for your barrel it would seem book data for the round is booik data for the round.

I've never used it but as I say it isn't data someone just came up with out of the blue but data from eiter Rifle or Handloader magazine.

Let me know if you want it and I'll e-mail you the files assuming I can still find them on my computer.

If this is a double rifle your accurate load is the one that regulates the barrels unless you have a sight on each barrel.  That is, the load that lands the bullets from each barrel close together at a specified range.  This will not be anywhere near the max load for the case, by the way.

Just to confuse things, there is a 9.3x72R and a 9.3x72R Sauer. The Sauer has a slight bottle neck. CotW says to use .38-55 data which makes excellent sense.

If you need more cases, email me. I have 98 or 99 new Bertrams I could be bribed out of.

Were I you, I'd load one of those 365s ahead of two grains of Bullseye or any other real fast pistol powder and fire it into a box of soft rags before I went any farther. Measure that slug and you'll know the groove diameter.
