alloy's

[white eagle]

I did a test today with alloy's
specifically water quenched w/w and air cooled
I used a 300 gr Accurate Molds p/b with a charge
of 17.0 gr of alliant 2400and fed. 150 caps..... distance of 50 yds.
I found in my particular gun ( S.S Ruger Bisley 45 colt 5.5"barrel)
that accuracy was better with the air cooled boolits
now this was the first test and in my gun
your testing and circumstances may be different
I just found it interesting :holysheep

Sometimes a softer alloy grips the rifling better, rather than being shredded by it, which can happen with too hard an alloy.

I have usually found AC WWt to be equal or better than WD WWt.

Plus 1, and I'd add, as long as the A/C wheel weights are at least Saeco 7(Bhn 11). When ww alloy starts getting a larger percentage of stick on weights, the hardness goes down and accuracy and leading follow. At least that's been my experience.

Don't stop now. That is a mild load of slow powder. Not like a full blown load of 296 or a fast powder that punches the boolit.
I find water dropped covers a wider range of loads.

The following are quotes from the book, The ABC's of Reloading.


"Hard alloys are a poor choice for making hunting bullets since they will either drill straight through or shatter rather than expand evenly."


"Hard boolits are a good choice for long range target use or metallic silhouette shooting where velocity and flat trajectory are important and there is no need for expansion."

so what are you saying
damned if you do and damned if you don't

What I'm getting at is there is some talk about hard boolits being a new thing, but that is not true. As you can see, from a published source, hard boolits are widely used. It depends on the application. Maybe the air cooled thing is the new thing. Just the opposite of what it's proponents claim.

Water dropped has always shot tighter for me from all of my revolvers, just plain WW metal for the most part. That is a bad alloy for hunting if the gun is too fast like my 45-70 at 1632 fps, it will drill a hole and I feel the slower loads I use in the .45 Colt should have a bit of expansion too.
WD has been no problem at around 1350 fps with any decent meplat.
None of my guns will shoot a 50-50 alloy even if oven hardened unless it has a gas check.
Air cooled from my .44 will scatter shots even with a GC but I found if I anneal the checks, accuracy improved.
Any air cooled WW, PB will scatter shots and shortens hunting distance. Recovered boolits show wide skid marks on the base band, just water dropping will correct that.
My next trial with the 45-70 will be 75% WW and 25% pure, water dropped with a GC. If accuracy is not good enough to 100 yards I will make a two part boolit.

:razz:
so true but for that particular set up if did good

That's where I'm at. I need to retest the HP with bh 19. If it can't shoot tight at 100 yds, then for me it's making a soft nose like you suggested.
