founds these loads for a 200 gr LRN for the alliant powders. looks like a reasonable starting point with the remaining 1.62cc's of case volume we have left after seating the cast bullet with gas check.


OAL    BBL     Primer     Powder     Grains    Muz Vel    PSI
1.575 5.6     Fed. 200    Red Dot     4.6        990        33,600
1.575 5.6     Fed. 200    Green Dot 5.0        1,015      34,000
1.575 5.6     Fed. 200    Bullseye    5.3        1,085      33,900
1.575 5.6     Fed. 200    Herco        6.1        1,105      33,900
1.575 5.6     Fed. 200    Unique       6.0       1,105      33,900  
1.575 5.6     Fed. 200    Blue Dot    8.2        1,225     33,900
1.575 5.6     Fed. 200    2400         10.0       1,245     32,800

i was figuring the opposite and the bullet would like slow extruded or ball powders, oh well, been wrong before

You need to watch Alliant's velocity figures.  This 125 gr JSP load:
1.570     5.6     Fed. 200     Blue Dot     14.5     1,795     34,000
actually clocked at less than 1500 fps out of a 6" Security Six.

Jeff, I ve had terrific luck with this load ... 6 grains of Bullseye pistol powder, 140 grain jacketed hollow point and winchester magnum small pistol primer.  I killed a buck ith it this past huntin season, at 67 yards( one shot kill) Hope that helps








I paractice gun control,  I hit what im shootin at

Sorry Jeff, misread the topic.  Hres my cast bullet( gas checked bullet) 158 gr semi wad cutter, 5.3 grains bullseye.  Also very accurate out of my S&W 28 and my Tracker 357.











I practice gu control, I hit what im shootin at!

the handles arrived and i casted up some of the bullets today. make sure you smoke the mold with wooden matches. using 90% wheel weights and 10% 50/50 (or thereabouts) 100 (+-) of them dropped out at between 178 and 184 grains. a few voids or dross ? not bad anyway, it's +- 1.6% weight distribution. i'm using marvelux to flux the melt if that matters.

if i have time tomorrow, i'll size them, and load some up and see what it does at 50 yards.

SG, when I used to cast a lot, I just used a paraffin or beeswax candle to flux, light the candle, drip wax in the pot and light the smoke on fire....drip a bit of wax in a spoon and gently stir a bit, skim the dross.....worked much better than Marvelux or anything else I ever tried.

[ScatterGunner]

beeswax or paraffin is better for fluxing, i agree. i have 2 small plastic cans of marvelux. at my last house, i used to cast bullets in the garage and ended up using marvelux to reduce the smoke and smells that my wife didn't like.

my all time favorite for fluxing is beeswax, i have a bunch of sticks packed away since we just moved, but i did find the marvelux in the same box as the molds, furnace, and other casting stuff so i used it this time. now i can cast outside on the deck, which i did today and i'll start using beewax again.

Scatter Gunner, If you are using a bottom pour pot, cover the melt with kittly litter, this will solve the need to flux. Marlevux is hydroscopic....it attracts water, so when you crank up your pot next time, be sure to lay all the spoons, dippers, etc that contacted the Marlelux on the pot so that the attracted moisture is driven off. DON'T stick thouse things unheatd into the melt....BIG NASTIES from that.

Melt down your alloy outside on a turkey fryer, flux all you want, used motor oil will do just fine, probably better than anything else you could use, lots of available carbon. After making ingots that will melt in your casting pot, just drop 'em in as required (I keep mine topped up) run your pot at teh lowest possible temp for good casting and it will minimize the oxidation that occurs, and that oxidation layer becomes the barrier that prevents further oxidation. Some use a laye of fine charcoal granules instead of the kitty litter, works well too.

A couple of exellent threads on this subject can be found doing a search for flux or fluxing at www.castboolits.gunloads.com
