Is anyone lead casting bullets for 300/221 ?

[este]

Hi,

I'm new to reloading and the fireball AR I want to build will be the first rifle I reload for.

I know a guy locally to me that cnc machines bullet molds for lead casting. I read somewhere that since lead has a higher specific gravity then say copper or steel that the required twist rate could change.

Is anyone making their own whisper bullets ? Any advice as far as lube coating them ? I had read somewhere that lead bullets don't need to be coated as the lead is soft enough to slip through.

I'm guessing this isn't so uncommon. But I figured I'd ask.

Also, if I'm going to have him make me a special mold, is there anything to look for as far as shape (esp of the tail area?) ?

Thanks!

este , I just got my mold to start casting for my whisper(check in the whisper reloading forum here), have heard nothing but nay sayers , saying it will mess your can up, it will plug your gas system up, have NOT heard from someone yet that actually experienced this for themselves, no insult meant for all the fair warnings being giving, I do appreciate their input and advice but I'm a little stubborn and will have to prove it to myself, I will be shooting strictly sub sonics and I really dont see where shooting lead that slow will have any of the fore warned leading issues. other than dealing with the lube being left in the can and posiibly gas system ???, I dont see the issue , bullets do not have contact in the can , its not being shot at a blistering speed so molting lead spray should be non existing, will report what I find out, as far as lube goes I would read some more maybe abc reloading, cast bullet performance, to start with. you definetly need to lube cast bullets also check out castboolits.com some guys over their shooting cast whisper bullets with factory molds regular from what I've read, also welcome to the forum

You should get a take apart can if you plan to shoot lead cast
bullets.
Anyone who has a 22 knows how the lead spray inside
of a 22 can buids up and not with blistering speed ammo, with a 30 cal can it will build faster.
You wont be happy after you shoot enough lead cast through
a sealed can and get a baffle strike or worse.
I'd hate to see a grown man cry but If you dont think this wont happen then go ahead.
Check the manufacture of your can and you may find out they say no lead cast bullets.

red dog I appreciate the input , I got a question, I know .22 does not have lube grooves and lube do you think that may have some play into why .22 cans have lead problems ? no protection at all, possible blow by, My thinking is the lube would very much help with any leading issues , as far as a can it would definetely be a "take down" can, weather lead or jacketed, no manufacture, I could not afford that, the tax is enough it will be built in house as soon as my papers come back. but I do understand the concern. I finished up some cast today they weighed in at 219 grns will be slinging some next week and find out how wrong I am, or right , for me anyway

I disagree.

22 leading problems have to do with the sheer number of rounds put through. I can dump a box of 500 22s in an afternoon. I nor would most anyone else be shooting 500 whispers in a row.

Since we are talking about moslty low pressures and slow burn I would expect the chance of molten lead to be small. A cleaning solution of 1 part peroxide and 1 part vinegar will remove buildup from a sealed can.

I will be making my can sealed. Will it gather buildup from lead ? Yes, but with cleaning every 100 or so this won't be an issue. Certainly not to the level of baffle strikes. That's my opinion anyhow. Then again I'm setting my can up for 338 so a 308 should gave a little wiggle room.

I figure in a long day I might blow through 100 rounds but since I prefer long range I doubt it will be that many

I see you went over to Silener talk and asked about the leading in cans
and the answer was from SWR the a maker of cans that
SWR has had several HEMSII's filled up with lead from cast bullets.
What you will find out is the wax on any bullet wont protect your
can in anyway and your can will fill up with 1/2 the rounds as 22lr
because of the size of the exposed rear of the lead to the flame of the fired
round.
The fire behind a 22lr bullet isnt even 1/2 of what you will be puting
behind a subsonic 300 whisper bullet.
But like I said go ahead and find out on your own.
Never mind that some of us have allready been through this.
You think some of us dont shoot 500 rounds in 1 shooting session! LMAO
I shoot 200-300 rounds of my 510 whisper single shot in one sitting and
double that with the 300 Whisper semiauto.
