22 boolits

[ian45662]

For those of you who shoot wheel weights out of your ar15s do you water drop or heat treat your boolits?

[runfiverun]

since you aren't gonna be going too fast, water dropping should do fine.
however getting those little 22 boolits hot enough for water dropping to help is most impossible.
i use a combination of harder alloy [4% tin and 6% antimony], hauling butt while casting, and water dropping.
or just using straight lino-type.
if i were gonna use ww's i'd add 1% tin, and then heat treat after weight culling.

I cast my ar boolits in a 75/25 WW/Lino mix, after weight sorting I GC and size then oven heat treat at 425 deg. for one hour then ice water quench,then apply FWFL
You can do your WW boolits the same, won't be quite as hard as my mix but should work just fine.

I wq mine, I also cast fast and use FWFL with Carnuba.

Bator mold 18gr of H4895 cycles the action, bore is spotless and shiny.

Want mine hard, at least 22Bh and preferably up closer to 30 for brittleness (guess that is a word) if I am going to shoot varm. I want them to break up on impact, and that seems to do it for me. If just paper, around 22 or so is fine, and I normally want someplace in the 2000-2300 fps. I water drop everything and I normally check, size, and lube the same day that I cast. I shoot Hornet, K-hornet, 222,223, and 22-250, and am in general satisfied with the accuracy and results.

Just curious, alloy ?

[reloader28]

I have never tried water quenching but I have thought about it. I oven heat treat cause I know I'll get a nice consistant hardness.

Alloy: Normally about half to 2/3 a pot of range scrap, about a quarter pot of lino, about half a cup of Mag shot, a little tin, and a little babbit to fill to the top. Nothing scientific, not weighed, and usually get w/water dropped, in excess of 22bh. If I want harder I increase babbit, and shot, and reduce qty of range scrap.
