For 2-3/4 hulls ? I've got a good supply of both Federal Plastic cases w/paper base wad and Remington hulls to work with along with a Lee .600 RB mold.

Ok, since nobody chimed in, I tried using 2 600's loaded in both Rem RP12's and Winchester WAA12R wads in front of 31.5 grains of Blue Dot.(Fed cases with paper base wads) I don't have a chronograph but judging from the muzzle report compared to my Buckshot loads (33 gr blue dot, 12S4 wads 9 pellets 00 buck) they could be a lot hotter. Spread was about 2-3 inches at 25 yards. I also tried single .690 RB's in Remington cases (high brass) with 24 grs Unique seated on a WAA12 wad with the petals removed and these seemed about right, similar to the 00 buck loads in the Fed cases in report. Don't think I'd try em any warmer though. The folded crmps aren't the prettiest you've ever seen, but they work.

I haven't tried any yet, but have read that Roll crimping the ball, just above the centerline is a good way to go for crimps. ;) I'm planning to do some brass magtec shell ball loads pretty soon. Just need a couple more items. 8)

baddad - I'm thinking your 'Hearing Test' assessment of your loads is about right. Your 2-Ball/Blue Dot is very mild, the .690"/Unique load should be pretty snappy, around 1,300+ FPS I'd guess.

If you're going to play with loads, a chronograph adds to the fun.:) They're inexpensive, unless you happen to shoot one (like I have).

UHH,,,,,,,,,,,,,,,,,,,I've had two chronographs in the past. One was mine, one was a borrowed one. :D I still have mine and I'll give you two guesses as to why it no longer works. ;) I've thought about investing in another, but the only thing stopping me is history repeating itself. :mad: I wonder how much I can add to the Blue dot 2 ball recipe without going too far ?

I don't want to claim how high you can go without getting into trouble. Using the Federal hull (rolled paper basewad, but not the Gold Medal), RP12 wad and a W209 primer, I would go up to 37 grains of Blue Dot. Those two .600" balls total a bit less than 1 1/2 ounces.

I do not have my .60 RB mould yet so can not compare weights.
But are .60 RBs that much less than the .69 RBs, my .69 RBs weigh 1.1 OZ each.

Two balls I cast average about 630 grains or 315 each. I don't recall offhand what the 690's were.

Thanks for the input:D

A .690" from pure lead will weigh 493 grains, a .600" will weigh 324 grains.

To calculate weight in grains (again, from pure lead):

Cube thr radius, multiply by 12,012.52.

Alloys will generally weigh less.

Stay away from soft lead.

Soft lead in multi ball loads will expand against each other causing increased sidewall pressure. Use at least WW alloy to avoid this problem.

That's basically what I did, weigh the balls then select a wad and powder charge for the weight. I believe I settled on a 1-3/8 oz load for the powder charge.

Combined the balls I'm casting weigh in at about 620 grains. In any case the poweder charge ended up being a little weak and could stand to go up a couple grains.
