Hey P Flado!
Today turned out to be a special reloading day. Ever tried a load and just ended up with a ....OH MY GOD!
WELL IT JUST HAPPENED.
I have been shooting lots of UNIQUE with my 405 grain cast bullets. I know its pretty fast burning and wanted a slower powder
to burn the full 20" of my barrel so....
I broke out my SPEER #14 BOOK and found a "COWBOY LOAD" FOR MY 500 GRAIN spire point cast bullets USING RELODER #7 POWDER.
START WAS 28 GRAINS OF RELODER #7.
I loaded up 5 rounds and jumped on the bench to shoot.
at 25 yards it hit exactly where my 405-12 grain Unique loads hit at about (1100fps)
SO OUT TO 100 YARDS!!!
only 1 bullet left.
shooting at a 1x1" piece of Gorrila tape on white sheet metal. NO HOLE SEEN AT 100 YARDS!!! (GREAT, I HOPE)
RAN DOWN TO LOOK!!! (DEAD CENTER IN THE 1X1" TAPE TARGET!!!!
RECOIL WAS MILD BUT THERE. BLAST WAS MODERATE. BRAKE WOKE UP TO GO TO WORK.
CLEAN BURN FOR SURE. HITTING DEAD CENTER WITH 1RST 100 YARD TRY? VERY VERY HAPPY.
TIME TO WASH, RINSE, REPEAT!!!!
THANKS FOR YOU CHARTS MAN!
MY MODERN books only have HIGH HORSEPOWER Reloder #7 loads which made me alway stray away from #7 !!!!
Who wants 500 grains @ 1600 fps?????

| Accurate/Hodgdon 5744 was recommended to me for my scoped Henry single shot. Is that powder a contender for just range shooting. I haven't loaded anything with it yet |

I do! I need to try to get further from the transonic zone in order to shoot 600 yards!

Just FYI... it's Accurate 5744, Hodgdon just sells it. As was mentioned above anything in that general burn range... AA5744, IMR or H4198, RL7... will work great, even at 100yds, for bullets in the 300-405grn range. Low recoil, fairly low charge weight, good efficiency.
I'm still dubious about the transonic issue. Tell you what I'm going to do, young fella... I know some guys that have forgotten more about heavy cast shooting than I'll ever know. Imma run it past them and see what they think.

I would really appreciate that, Charlie98! And while speaking with them, please also ask them this: To minimize any transonic effects, how fast can you safely get a 500g 45-70 bullet moving if using powder coating AND the right smokeless powder in a 30 inch barrel in a rifle action safe to 30,000 psi? Or, would a lighter weight cast, powdercoated bullet at high velocity (with high enough BHN) potentially be accurate enough in such a rifle to shoot at least 600 yards?

If I find myself using caps, I put new batteries in my hearing aids and switch to lower case. (lol)

Ok. I have no use for
small letters. Font size has no volume at all. If I say 10 grains or
10 GRAINS the velocity with Unique is exactly the same . Only THOUGHTS of loud is in your head.
Carry ON!

Thank youAshleyOverstreet: Your MOA rnage in that scope might not be enough to handle the longer ranges you mentioned you want to try. I am shooting a sharp-ogived 500g bullet cast from the Lee .459 500 3R mold, with a muzzle velocity of about 1350 fps, powder coated, and a ballistic coefficient of about an actually verified 0.43. My Pedersoli Sharps replica has a barrel length of 30", so it is similar to your barrel length.
I am currently sighted in at 150 meters (Canada) = 164 yards. So far, I find I can repetitively shoot 1.5" to 2" five-shot groups which is 0.87 to 1.16 MOA at that 164 yards, with the 3 closest shots in each group making 0.75" to 1" groups (0.44 to 0.58 MOA) within the 5-shot groups. I cannot go higher in muzzle velocity, because I am already at 27.5g of 5744, which is 0.5g under the 28.0g load table limit for a replica type rifle like my Pedersoli (psi at 28g would apparently be 28,000 psi). And from ladder testing, at 28.0g the accuracy was not as good.
The online ballistic calculators say that due to the low muzzle velocity, to go to 600 yards, even starting from the 164 yard sight-in, I will need over 60 MOA of come-up, and for 800 yards like you are apparently contemplating, I would need over 95 MOA of come-up.
I am using a Leatherwood Hi-Lux 6x semi-authentic "Malcolm" full-length telescopic sight with a Hi-Lux CNC-machined micrometer rear mount that enables over 200 MOA of external elevation adjustment. I am using only about 25 MOA of that range right now for 164 yards, so I HAVE the necessary come-up range. But if you have only 14 MOA of come-up available, you'll need to either use a sloped mount or a bullet much lighter than 500g. And of course a lighter bullet will have a poorer ballistic coefficient.

Good information

I load 405 grain bullets cast from a Lee mold with 4198 data from the Trapdoor approved loading section of Lymans 4th edition. Very enjoyable to shoot but still moving along around 1260 FPS from my Trapdoor carbine.
