Favorite cast bullet mould for hunting with 10mm?

I personally see very little value to rock hard bullets. I like them to meet the traditional criteria for hard cast, which is BHN 12-16. That can be achieved with air-cooled WW.

Really hard bullets won't deform elastically and fully seal the bore. This results in jets of plasma escaping around the sides of the bullet. These high pressure/temperature jets will melt little channels in the sides of the bullet, and leave leading.

This is the reason you will hear folks say their gun "won't shoot lead without leading". They don't slug the bore, buy bullets that are not groove diameter + .001" and a little leading. Then they go harder, and get a lot of leading, because the bullet base can't obturate.

If I am going to water drop, I will mix isotope lead 50/50 with pure, and then add a bit of tin to bring it up to 2%. This gives me a bullet that is about 16-18, but is a lot more malleable than straight WW water dropped.

SQL: Agree that hard cast are overrated and can actually cause problems.
Why is your brass shorter than standard? To allow use of more cast bullets? Have a different chamber?

It's not. I apparently can't read calipers. My post was amended. Good catch!

Sure tempted to order that NOE 200-grain PB.

I have a couple that wrk, but they are not what I wnat or really like...

I like a 200 WFN GC. I have bought a couple hundred. and like them allot, they feed well in all my 10's and shoot accurately. wow do they "smack" a target out at 100! Much like when I was a boy and started shooting 45 colts at distance... that "smock" sound returning after the shot as the bullet strikes the target is rewarding.

That NOE bullet looks good but for the GC.

Should have that mold in hand in a day or two.

I have an Accurate Mold that drops a 190 grain FNGC that shoots really well out of my Glock 20SF.

Thats a good looking bullet!

I really want a 200, but 190 will surely do just fine. ${$default_smiley_smiley}$

Randominator, those do look great. What gas checks are you using on them?

Benchrst · February 17 2016 09:47:25 PM MST

That's a good looking bullet ${$default_smiley_smiley}$

Reminds me, haven't cast in months!

I cast up 320 eight pound ingots on Saturday/Monday. Does that count?

BillinOregon · February 18 2016 01:18:34 PM MST

I am currently in a back brace, and 320 8-pound ingots strike me as painful. Man, you must have a heck of a melt furnace!

I ran two dutch ovens on a dual camp chef for about 8 hours both days. Went through a tank and a half of propane. I was tired and smelly at the end of both days.

Can't shoot an ingot, so only partial credit ${$default_smiley_smiley}$

I need to find a wide meplat FN non-GC that drops 180 - 200gr.

NOE probably has something.

I use the 40 caliber checks made by Gator Checks.
