Isn´t the large pistol primer too soft for the big cartriges? I am aware there is no concern with your single shots, but would you still use LPP´s on a horizontal magazine like a 45-70 lever action?

@carlos45703030

Its what the Magtech 24 ga.case was made for and its specific do to the depth of the primer pocket. If you were using regular 45-70 brass you'd have to use rifle primer since thats what was needed due to the depth of the primer pocket.

Great video Darren, I especially enjoyed the casting bit, as that's something I haven't quite mastered yet.  I struggle to get good mould fill-out and clean bullets. I've figured out the 'clean bullets' issue now I think, it appears my pot gets too hot, it's a Lee 4-20lb or something like that, I have it set to 2 or 3/10 and I'm sure it's too hot, I get nice 'clean' lead with a mirror surface when it's warming up, but then it goes purple/blue and I'm constantly skimming dross off...

[ginsboy2003]

@P1LGY I was having problems with proper fill out, but I got the mold and lead a little warmer and started using a ladle and I get better results. The faster I got the lead in there the better the results are. You actually need to learn your equipment so to speak. The heat setting my pot is on now is too hot for my little 30-30 bullet mold. At this setting they come out frosted instead of shiny like my MH bullets. I rarely skim the dross of when using clean lead ingots.

@P1LGY with magtech brass you need to FL resize becaue its balloon head if your using soild head then you can neck size with my jamison cases ive goten about 10 shots with neck sizing and annealing every 3 or 4 shots

Great video bro

[ginsboy2003]

@P1LGY I think you'll get a lot more than 3 firings from the cases.  I think annealing is the key so your doing exactly what you need to be.

[P1LGY]

@ginsboy2003 I read some people were getting 3 firings, and since for me it's 52 pence/shot (assuming 3 firings of brass) and the brass makes up 33p of that, so I was keen to make the brass last. I'm still on my first box, they've had 3 firings, and they're looking good still. I'm annealing in between every shot at the moment, because the FL sizing die seems to do a lot of work on my brass...

[P1LGY]

@ginsboy2003 I might try a ladle then, I've been using the bottom pour, but it isn't that slow, I have it set right up to max, so it drips a bit, but it does that when it's turned down too haha The other problem that has now appeared is the sprue plate bolt, it keeps coming undone, rather annoying, I think the lube was burning off, I have some high temp stuff to try, what do you use, if any?

[ginsboy2003]

@P1LGY No, I weighed them after I cast them, after casting I had 35lbs of bullets haha. I haven't shot them that much, but I've got 3 firings on the brass I have. After 3-4 firings with magtech cases you should anneal the necks again.

[P1LGY]

..the 'dross' too weighs a lot, I'm sure most of it is lead. On my next casting session, I'm planning to sit a small bundle of steel wire (from wire armoured cable) in the lead to dissipate the heat, I'm hoping I can just add or remove wires until it sits at about the right temp, we'll see! I'm currently shooting them as cast which is about .469". How many reloads do you get from your brass by the way?
