Hello. About ten years ago I was heavy into casting my own rifle and pistol bullets. Whenever I had a question I always asked my knowledgeable friend that owned a reloading store. A few years ago he passed on and I had other priorities in my life. Now, I'm getting back into casting again because of the surge of retail bullets and the future increases predicted.
He gave me a formula for blending leads for Lyman #2. I seem to have misplaced my mixing data. According to Lyman's Cast Bullet Handbook, the recipe is:
9 lbs wheelweights and 1 lb 50/50 or
4 lbs Lino and 1 lb 50/50 and 5 lbs pure Pb
I seem to recall a formula he gave me for just wheelweights and Lino I think. Was I mistaken? Are there any favorite recipes anyone on the group use?
I would like to cast 30-06 and 308 bullets around 180gr. Does anyone recommend pure Lino for higher velocities? Also, does anyone remember the BHN for #2?
Thanks - Rick

do you have the 3rd edition lyman cast bullet handbook that you referred to?page 57 has a chart giving the percentages of different alloys.page 58 has a chart giving the physical characteristics of the different alloys.i prefer to make my #2 from ww and tin,saving my lino and mono for adding hardness/antimony when needed.ww will need to have tin added to make #2. i only go to 2 to 3 % tin and have good castability in my large calibers.a mixture of 50/50 ww and lino will have about 1.75% tin and 7.5% antimony.it may need to have the tin bumped up 1 or 2 percent to cast a shiney bullet but may cast a good but slightly frosty looking bullet as is.the BHN will be between 15 for #2 and 22 for lino.i would guess 17 to 18 bhn.wheelweights blended to a #2 alloy have a distinct advantage over a virgin #2 alloy or lino. they can be heat treated to 5 BHN harder than lino and are cheaper to boot.refer to page 115 for heat treating.most of the loads in the handbook are with #2 and a 180 gr in the 06 should work well with it.i have recently aquired a A.O.Mashburn 03A3 sporter built in the late 40's in 30/06. i am looking forward to working with the 2 moulds that i have.a lyman #311291 170 gr and #311284 210 gr.

I too save what little lino I have for very specific projects, and cast and shoot mostly with WWs, often with some 95/5 solder added. Never much bothered with heat treating, I don't push my rifles over 2000 FPS, haven't seen the need.
Here's a target I just found while doing some cleaning/straightening up. 200 grain Lee RN at .309, Lyman Black Moly lube, over 18.0 SR-4759. Fired in a stock M-1917 from a rest at 50 yards.

Yes, I have the third edition and have my nose buried in it again. I don't know what I'd do without that book. I looked at Amazon.com just to see if they still had that book available and it looks like they're not. Yes, I did see the chapter about annealing the bullets and I'll see how much harder I can make them.
Thanks for the ideas Weezen, I'll take that to heart. I like those shots Charley posted too. I hope to match that.
Fortunately I ran into a huge pile of Lino at the printers where I get my printing done. My friend there told me they had shut down their Linotype machine because of insurance and EPA reasons, and he showed me his back room where he stored bars of LT for years. Needless to say I "disposed" of it for him in rapid time. I don't think I'll ever run out.

if you have a large supply of lino you are set.lino will make a lighter bullet,as well as a larger dia.refer to page 115.lino will not heat treat,nor is it needed.

The Cast Bullet Association has a spread sheet that calculates what your alloy should do. If free, http://www.castbulletassoc.org/downloads.shtml
Look down the page to alloy calculator.

Your Welcome.
The weather here is so bad today, that the wild game all stayed home, so I can't try out a new bullet.
What ever happened to Global Warming?
