I had to give up on these 300 gr cast
« on: June 27, 2009, 02:04:01 PM »
nevermind the 243 brass I picked up at the range, yes I'm a brass hound... ;D

anyway I had these .429 300gr cast that I bought in bulk for a good price because it was
an open package at gander mountain one time.


anyway I was pulling my hair out, bullets shooting all over the place...what was
weird was, there never was a keyhole.  well, I thought that the blue wax (lube) was
sticking to the sabot and screwing things up, so I boiled the bullets and got all the lube
off.
well they still wouldn't shoot worth crap, I kept blaming other stuff
today I gave up because the 240's (on the left) completely spanked the 300's





so maybe I can shoot them out of one of my .44 mags (vaquero or carbine), but I don't know
if I can use them now without the blue wax (lube) on them

anyway I have no idea why they didn't work out, I tried all kinds of different powder charges

 ???

but I don't care. its 240's for me now

The p=roblem I see is with the length of the sabot, causing an inbalance so the bullet can drop out of the sabot rather than have the petals open and separate.  I bet if you looked at the sabots, they barely opened or did so only on two petals.  At least when I used longer, heavier bullets, that was the problem I had.

I totally agree with Bubba. Those old short green MMP's were the first sabot I ever shot, over 20 years ago out of my first inline, the MK-85. They were designed for the shorter 240 gr pistol bullets.

John, if you want to shoot those 300's, get some green Harvester Crush Rib Sabots. They have longer petals with less of a gap between the petals, and they shoot real good out of my NEF with other bullets. I never did like hard cast much out of mine, but I had some 240 gr left over from my .44 reloading days that shot ok, but not what I would call really good. I wouldn't shoot a deer with a hard cast anyways, just paper occasionally.

man I am getting good if busta agrees since he is the nef guru.  However, I have to disagree with the cast bullets.  I exclusively shoot a 250 grain .429 round nose bullet I mold with a lee mold. They are very accurate and deadly on deer.  I also shoot them out of the crush rib sabot.  But I also weigh everyone of them on my digital scale and put them through a 429 sizer, so they are very uniform.  I have shot deer out to 100 yards out of my sidekick with deadly results.  But the main reason I shoot them is cost.  It is much cheaper.  I use 85 grains of loose triple 7 fffg and either my 25 acp breech plug or the new metrics unlimited plug with awesome results either way.

Bubba,

Are those "HARD" cast bullets? Are you casting them in pure or near pure lead. Cast lead bullets are very effective and shoot very well within their limits, it is the "hard cast" bullets that I don't care to use for hunting.

I have also never attempted to take a deer with a "hard cast" bullet either, but that doesn't mean they don't work. I have taken several with pure or near pure soft lead however, and they work very well with light to moderate charges.

I use about a 2/3 mixture of pure lead and wheel weights which are harder. They expand well and drop deer well.  I guess to say they are hard cast would be stretching it.  I just try to stretch my lead a bit and the wheel weights are free.

OK, got ya. The hardcast bullets I have are VERY hard, too hard IMO. They were cast for target bullets in the .44 mag.
