Yes, I would say you are right at the threshold where leading could begin to be a problem, but if it works then there's nothing to fix. I got off to a poor start with the new Chiappa '92 in 44-40 by using Hornady's cowboy 200 grain cast. They spec them at .427 (right on the box), but in reality they measure .425. So, ya, after loading 20 ahead of some reduced charges of Unique there were no groups, some missing the paper, and others keyholing. What a mess when I looked down the barrel. You can't always rely on the manufacturer's specs. I've got a bunch coming from the Bullet Barn in .429, since the rifle slugs out at .427. I may even try some H-110 at some point too then. Anyway, an interesting branch of the hobby. BTW, I can't find a 44-40 jacketed bullet anywhere in Canada.
That looks real good Ted. Do you do your own casting?
Anyone use an old style Coleman stove for casting?
Tagged for interest.
I used one of the naptha type stoves for melting scrap lead and wheel weights and it worked fine. It's not the easiest heat source to use for casting because it's hard to regulate the temperature. The gas pressure keeps bleeding off and you need to pump up the fuel pressure. It's hard to regulate evenly but it can be done. Propane is easier. The quality of your bullets depends on how well you can regulate the temperature.
I strongly disagree
Not sure which part you are disagreeing to , but in my experience temperature is very important in making a weight consistent bullet. I have used the old coleman the lpg coleman and electric pots . They all have problems keeping the temp. consistent as the lead level goes down. My solution is to use large pots , and a thermometer . I try to keep the temp. within 5 degrees F. As the lead level goes down , I add a few sprue's to keep the temp consistent. I am dipping for BPCR bullets 500+ gr. bullet , and am looking for + or - one tenth of a grain.
For cowboy action bullets , I bottom pour . And if it sort of looks like a bullet I shoot it LOL.

Why would the temperature be critical?
Once you get a good fill and no wrinkles, the same mould cavity will produce the same weight and shape bullets regardless of the temperature.
In my experience the only thing that influences the bullet weight is dirt between the mould halves and breaking the sprue too early or too late.
Please explain why you think a hotter alloy results in a different outcome?

Yes, I could see that being a very useful application and much easier to manipulate in a tent.I have a nice Lyman mold that casts a 265 gr Keith bullet for the big Colt.
Loaded to over 1200 fps using H110 and magnum primers in my heavy Sauer single action, it was a very comforting sidekick while guiding forty years ago.
