Just don't compress it. You might have to check seating depth of those 500gr bullets.

As mentioned, the only rule with Trailboss is don't compress it.

Measure your seating depth , mark that on your case.

Fill case to that mark.

Weigh that powder

There is your max load.

No compression. Understood.

I was going to measure by weight and go from there. Interesting that it's volumetric.

I'll make up some dummy rounds and play with seating...

Oh my, what am I getting my self into...

(308 case as reference)

In case there are zombie dinasaurs hiding behind a wall across the street lol.

Now to work out Trail Boss load for this bundle of goodness...

Few lessons came from this.

- this is a lot of lead. A lot.
- pouring this much lead heats up the mold too fast, so casting is slow.
- I suspect I may have a bit of zinc in there, will check hardness in couple of hours. Should be fine.
- I think I may have outgrown the furnace - bottom pour is the way to go and will need to upgrade.

So are you shooting it out of a lever action or a single shot ? I seem to remember it was a single shot ? If so,you can seat the bullets out a bit further to squeeze in some extra powder

Getting about 13.4 BHN. Guessing it may (or may not) harden a little more over a week. Acceptable hardness.

Got my doubts the hardness will change with time.

Yes, me too, OB. I've actually did a bit of backyard experiment with this. Made a few bullets using lead and WW. And measured them daily for few days. No change.

I actually have it somewhere, will post at some stage.

Either way, 13.something is acceptable, I am going to throw a lot of it... Just not very fast LOL

I know this goes some way back Pete....but would like to know how you got on with you 570gr load here. No probs with stabilisation? Did it group ok? Did you slay a buff with it?

It didn't stabilize well. Gave up on it. The buffalo hunts fell through thanks to useless mates who couldn't organise a f*** in a brothel

Well that sux!!
I’m shooting commercial hard cast 500gr RNFP’s (Spartan Projectiles) with great results over 33.5gr of 2207. Turns up 1380fps out of 16” barrel.
I’ve got an old H&R Model 155 (cost me a slab!) that I went full retard on for smacking plates out to 400yds.....20 minute pic rail, 2-10x44 MOA reticle Bushnell, muzzle brake, spray canned it ‘coyote tan’ as a protest against the tactards....I really built it to give my ‘tactical target shooter’ mates the s**ts.
I swear it’s more fun ringing steel with it at 300 than at a km with a ‘real rifle’!
The bloody thing shoots 1 1/2” 100m groups too.

Hope your 45-70 days aren’t over bloke!

Regs,
Tank.
Keep calm......and hold centre of mass.
