Casting for 30-30 and 36.06?
 
Anyone done any with casing and powder coating for these rounds and devolved base loads?

I was looking at the Lee 2-Cavity C309-150-F gas checked bullet mold. They also have a 160 and a 170 but my buddy and I were talking and 150 grains has killed everything we have every shot.

I was wondering abut the hardness of the lead and powder coating with the higher pressures. I tried reading on other sites and many are doing it, but not going into a deep dive on explaining it.

I have the round nose version of that. I did not have much luck but that was ONLY because I really did not know what I was doing (if I even do now) back then.
I have had good luck with the 312-160 in almost anything I have tried it in around 30 cal.
https://leeprecision.com/mold-dc-tl312-160-2r.html

It worked well in my 308 rifle, Mosin, 300blackout, and Argentine Mauser.
I powder coated it then sized it appropriate to the rifle.
I have always used a gas check with it though.

I'll look at my notes but I target around 1600fps with it using medium burn rate powders Blue dot for Mosin, H110 for 300BO for example. Blue Dot for Mosin gives risk of double charge and I have implemented 2 check methods for making sure that does not happen.

Now, I cared about accuracy and reliability of cycling and not expansion though.

BTW this mold I used would NOT work for 30-30, just 30-06 with that pointed tip

I thought 308 was sized to 309 and isn't 312 a bit big?

I know pointy bullets in a tube magazine is no good. I have no problem if it can't use the same mold and 30.06 used pointed bullet and round nose for 30-30

It sizes down to 309 and I have not had any problems with it.
Look up that and the 155gr one and there is LOTS of people talking about it.
I got turned onto it here by John when starting Powder coating.
I've seen posts online of people size to .311 before going to .309 but I don't do that and get good plinking accuracy (about 2MOA) John told me to push on the gas check PRIOR to powder coating. That works for me but I do have to look for the few where it comes off when swishing them around. If you care about accuracy, also check that the GC is on fully by looking at the gap between the GC and the lower lube ring gap. If I cared more about accuracy and consistancy in a lever or bolt, I may have preferred to go xlox/alox lube but I do bulk plinking steel with them.

For hunting loads, stay around 2200 FPS using 4198 powder. In a sporter barrel, that is about 32 grains. For the 30-30, the best hunting powder is IMR3031. You can get about 2000FPS or so with 28-29 grains.

I can tell you that they will give you cloverleafs at 100 yards from the bench in my guns. One thing about 30-30's. If you have a Winchester 94, you need to slug the bore as they run big.

My 30-30 is a Marlin 336A

When using PC'd bullets is it recommend to keep the velocity down around 2,000 fps? I have seem people shooting 223 PC and doing 2500 or better.

I have been using the Hodgdon reloading center for information like this but they don't list cast PC bullets for rifle rounds. Closet thing is round nose lead bullets for the 45 colt. I charted all the data for 30-30 and IMR3031. When I look up 30.06 they don't even suggest 4198 as a solution. 3031 is running at 2670 - 2880 FPS

Are you getting that info on the 4198 and 30.06 from a reloading book, software program or just long acquired knowledge? Also, half to a quarter of all rounds I load will be a hunting round. I only shoot to be comfortable to kill with it.

What if I start with wheel weights? Does that make it less than a 3%? ;)

The Lyman CAST BULLET Reloading Manual has those powders listed. But much of what I have learned is from being a member of the Cast Bullet Association and the Fairfax Rod and Gun Club long long ago.

Thanks, I ordered the manual.

It will broaden your horizons for sure. ;)
