bigfoot, thanks for the reply, i have just recently bought a cz-550 in 458 wm.
i am trying to find a bullet between 450-500gn. cast fngc.
i have looked at ballisticast, they have a few that might work. i have been too busy to try out marshalls 450gners. if any luck at all, i will get to try them out sometime this weekend. i was hoping to find a 450gn gc mold that would give about 2200-2300 fps.
what kind of bullets, mold and lube do you find to work. i am just starting with this caliber, any help would be greatly appreciated.
I use an alloy of wheel weights and lead from an industrial source ( similar to WW ). Add enought tin for good fillout and drop into water from the mould. They come out hard, they can't be scratched with a thumb nail.
Any of the above bullets shoot well, the 405 gr the best. After reading about high velocity pistol bullets I use a soft moly lube. I realize that there is discussion about what is better, this seems to work for me.
They are sized to .459, good crimp, the proper dose of 4895.
I use 4895 because it is available for a reasonable price and works in 458 WM, 444 Marlin, and 45-70.
I do get some leading but I believe it has more to do with the high volume of rounds I tend to shoot. The barrels get a little warm, especially in the summer heat. It does scrub out easily with ED'S RED and JB.
The 458 should reach over 2100fps with the 405 - 440 bullets easily.
hello bigfoot, thanks for the reply, i tried to order the lyman master casting kit from midway. but they are sold out. and won't be available till about august 20? oh well.
i have asked about the lee sizer kits, most people say it is good for the pistol calibers, but not much of anything for the rifles. hopefully soon i will be able to get this show on the road.
i so far have 5, 5 gallon buckets of ww, just waiting to be cleaned. i figured ww dropped into a bucket of water should be good for my use.
hunting and shooting anything this side of the big ponds.
bigfoot, the more posts i read, the more it seems people who use/have used lee sizer equipment, they like it. i think i will order one soon.
midway also has a chronograph on sale for about $76.00. this will help as well.
actually this is what i am waiting for. it should be in on the 5th.
on the quenched ww's, if there is not good mold fill out, i will try a little chilled magnum shot mixed in. i have read that 1/2 cup #4 chilled mag shot should be about right for 20lb of ww.
ok all, i understand how to lap out an aluminum mold, but is a cast iron mold the same, just more time consuming?
this is the saeco magnum 465 gn, fngc double cavity.
if i can open this mold out to .462" then size down to .4605-.461, then i will be in business.
