Getting the 375 H&H ready

[fiver]

you know they make a fan that mounts right on the front of the magma pot.
it blows straight down, and you can make a plate for the bottom with a small nipple tack welded on it to concentrate the air right where you want it.

The 375 h&h is a rifle i have always wanted but never had. I'd love to have one decked out with flip up sights on a safari type ramp. I've always heard it's a superb cast bullet shooter.
Maybe one day.

Good morning
Why not run two molds at the same time ? We do it all the time when pouring large caliber. Does seem to help with the molds not overheating.
We also shoot 375's. Have a CZ but our favorite is the 1895 repro with a 28 barrel. Got it from CDNN some years back when they were dumping someone's excess stock at under $800 delivered.

hey Mike.

I have tried 2 molds, i see a lot of guy's do it, I can't ever get it to work out for me.
one mold is too hot the other is too cold and I end up chasing my tail around in circles.

 

[Rick]

Not only that but casting to me is a relaxing activity, using two molds at a time make it far more like work and takes a good deal of the fun out of it.

 

[Brad]

Two moulds never worked for me. Seemed I was always feeling raced for time.
I just need to keep a count in my head as I go. Once I got the count right I was shocked at how much better it went.
Only thing I need to do is watch the distance from ladle spout to mould. If it isn't far enough I seemed to get voids, I need a little velocity on the lead as it enters the mould.

 

[fiver]

the longer ones generally like a straight in the hole fast pour.
some of them don't.

 

[Rick]

I've also never used any kind of a count or watched a clock while casting. Just watch the bullets coming out of the mold and any variation in mold temp quickly becomes apparent, adjust as needed.

 

[Missionary]

Using two can be a balancing act for sure. For us it seems to work better if both molds are 2 hole about the same caliber and /or weight. But especially both molds must be the same material.

 

[Brad]

I need to learn to stress quality over quantity.
I got 90 good bullets for the 375 in the last session. Took me maybe 50 to figure out the right cadence.

Faster is not always better.

 

[Rick]

I can say in all honesty that never once have I fired up the pot with the intention of seeing how many how fast. Never! I cast until I have the needed number of bullets that I am happy with.

Probably why I don't have a progressive loader. Never have I loaded ammo with the intent of how many how fast. I load until I have the required number of whatever I am loading at the time and know exactly that they are what I want.

I have several RCBS double cavity moulds, in pairs, just so I could cast pistol bullets faster. It just takes practice, but like Mike mentioned, two steel moulds works great, but for me, one aluminum and one steel is really rough going. Tough to keep a Star fed with a two cavity.

 

[KHornet]

I have run two molds with fairly heavy 30 cal and up and had no problem.
Tried it with 22's and 6MM, and was a no go. It is tough enough with the
little ones to cast fast enough and hot enough.

[Winelover]

Until I started buying moulds, with 3 or more cavities, I always cast with RCBS 2 cavity moulds in tandem. The steel blocks hold heat better than aluminum. Never used a hot plate, either. Most of the time, I would use say a 35 caliber mold and a 44 caliber, makes it easier to sort the bullets, later.

 

[Rally Hess]

I tried that a couple times too Winelover. Cast with the 150 KT and 245 KT at the same time. Funny how much they looked alike, until I got to sizing them. LOL

I’m of the same mindset as Rick. As I cast I have relied on visual inspection to monitor bullet quality. I try to cast at an even pace and look for smoothness and sharp edges. I add my sprues back to the pot as I cast. This seems to help with consistent flow speed from the pot to the mould. I start out at max pot temperature and when I notice a change in sheen of my bullets, I drop the temp back a little. I’ve never noticed frosted bullets showing rounded edges or lack of proper fill-out. For plinking loads I cast faster and end up with quite a few frosted bullets.

On my last casting session for my 9.3x62, I started monitoring my cast temp with an infrared temperature gun. I can check my mould temp and any change my alloy as I add my spues back to my pot. Interested in my end results, but have not had the opportunity to validate my results yet.
