If you read deeper in those Ideal handbooks, there's an interesting thing about the hardness of bullets they recommend for rifles using black powder. That goes something along the lines of if the bullet is under groove diameter they recommend a soft alloy such as 16-1, if the bullet is groove diameter or slightly over they recommend 10-1...
And in one of them they say 15-1 to be the best for general use..

Hey Mike, if that is your secret you whip my hinder with I will start using them :D I have a couple 5 gallon buckets full and several 10# & 2# ingots of the old stuff :)

Hi Kurt! It's all I've ever used since I started playing this game, but they're getting harder to get around here I'm glad I've still got a good supply!

I have a pretty good supply. Mixing it this way I could stretch my supply out for a very long time.

With 40+ years in the automotive business I've managed to salt away a 5 gallon bucket or two of lead alloy WW. :D

The trick is to not fill the buckets to the top.
But if it happens, you then need strapping young employees to lift them into your truck.
5 gallon plastic buckets of lead are heavy and the wire handles always break off when you lift a full one.

Nowadays all WW are zinc and more commonly steel, even the stickon ones.
We haven't been able to buy lead alloy WW in years.
I understand from a couple of customers who own roofing businesses, that roof flashing is also turning to Zinc based materials.

Personally I buy all my casting alloys in whatever mix suits me for the application.
I'd rather cast and shoot than indulge in any type of personal Alchemy.

Ha,
I just scored another FULL bucket of WW from the local garage as I was getting some tires mounted for the lawn tractor. Close to 100#
Of course, it will have to be sorted to get rid of the stick ons(lead and lead impregnated rubber), steel and the Zinc ones
Last bucket from them, it was probably 80 pounds good lead alloy COWW , and the rest the other stuff. the lead stick ons will be accumulated
and then melted and fluxed and cast into muffins for (pretty much) pure lead for making up 19+1 lead-tin alloy for my 25-20 for breech seating.
The zinc and steel ones eventually get sold along with aluminum cans and other stuff to the recycle outfit nearby
The "true" lead alloy ww will go into my 9+1 COWW/Lino alloy for BPCR and most other rifle and pistol uses.

Bruce,
I am currently only breech seating the NOE Mos tapered 117 grain bullet in the 25-20 wcf Hoch for Schuetzen matches.
But a few years ago, I was breech seating 480 gr PP bullets in my 40-72 for BPCR. I just inserted the bullets into the chamber
and then slid in a cartridge loaded to the top/ 0.060 ldpe wad at the case mouth

Yesterday I had a chance to test out the antimony alloy. I am very pleased with the way it preformed on target. I used the 14:1 first and then the 16:1:4. 15 rounds of each were fired and I had slightly better groups on the ram silhouette at 500 meters. The antimony Bullets did hit slightly higher but not as much as I was expecting. I do have some interesting velocity numbers though. Since I am able to measure the speed of the bullet at the muzzle and again 100 yards down range I am able to calculate the BC. Based on the numbers that I plugged into the JBM ballistics calculator the 14:1 had a BC of .45 while the 16 pounds of lead 1 pound of tin and 4 pounds of wheel weights had a BC of .5. I think this is a sight that the antimony is controlling the nose set back. According to this same calculator the harder alloy should shoot about 8 MOA flatter at 1000 but who knows if that’s true. We will find out though. I feel safe in mixing up a large batch of alloy although I think I will add just a touch more antimony and run this alloy in the 2021 season.

Well, I guess the secret is out! Thanks, Ian! Now I'll have to find a new advantage!

good post ian.
while the improvement in b.c. reduces drop, there is an even better gain had by this.
for drop, you can adjust the sight to suit.
where more b.c. shines is in reducing wind deflection.
at 1000 yds this can help scores.
0.1 in crease in b.c. is very significant, but 0.05 is noticeable.
your jbm programme will show this, as will the target.
stability will also be helped a little, as the harder nose having reduced drag will allow the centre of pressure to be a little back towards the centre of mass.
this assuming the bullet is not too long for the twist.
